Klemen BERGANT, Zalika Črepinšek, Lučka KAJFEŽ-BOGATAJ

ABSTRACT

Paper discusses the similarities and differences in predicting the full flowering of apple tree (cv. 'Bobovec'), pear tree (cv. 'Pastorjevka') and domestic plum tree. The study was conducted at University of Ljubljana. Input data were standard weather and phenological observations of Hydrometeorological Institute of Slovenia. First average monthly air temperature and average monthly amount of precipitation from January to April were used as predictors for flowering of fruit trees during the time period 1967-1996 and in second case input data for models were phenological data of autochthonous plants: first leaves unfolded of Betula pendula ROTH, Fagus sylvatica L. and Tilia platyphyllos Scop. Two different approaches were employed for predicting of full flowering of apple tree, pear tree and plum tree: the linear multiple regression and correlation analysis. The date of full flowering for all tree species is strongly correlated with the first leaves unfolding of birch (R2 is from 0.61 to 0.91) and in case of pear tree and apple tree also with first leaves unfolding of beech (R2 is from 0.62 to 0.66). Also strong correlation with combination of average March and April air temperature was found for flowering of apple tree and plum tree, for pear tree the full flowering was correlated with combination of average February and March air temperatures. In case of apple tree 76% of total variance was explained by linear multiple regression model between full flowering and air temperatures, for plum tree 55% and for pear tree even 91%. The multiple regression model for predicting the full flowering on the base of March and April temperatures have great disadvantage, because the predictions can be made in case of apple tree only 2 days ahead and in case of plum tree not even that. On the other hand, the prediction of flowering for pear tree can be made 22 days ahead. The full flowering for apple tree and plum tree in our case were not correlated to average monthly amount of precipitation at all. This could be expected since in Slovenia, water availability in the spring is sufficient for plant needs.

PROGNOZA SPLOŠNEGA CVETENJA PastorjevkE (Pyrus communis L. ), BOBOVCA (MALUS DOMESTICA BORKH) IN DOMAČE ČEŠPLJE (PRUNUS DOMESTICA L.) – PODOBNOSTI IN RAZLIKE

Obravnavane so podobnosti in razlike med napovedovanjem splošnega cvetenja pri hruški (cv. 'pastorjevka), jablani (cv. 'bobovec') in pri domači češplji. Analiza temelji na podatkih fenoloških in meteoroloških opazovanj Hidrometeorološkega zavoda Republike Slovenije. Kot prediktorje splošnega cvetenja pri vseh treh sadnih drevesih smo uporabili povprečne mesečne temperature zraka in količine padavin za prve štiri mesece (januar, februar, marec in april) v letih med 1967 in 1996. Poleg klimatoloških parametrov smo kot prediktorje splošnega cvetenja uporabili tudi podatke o pojavu nekateri zgodnejših fenofaz samoniklih rastlin: pojav prvih listov pri brezi, bukvi in lipi. Za izdelavo modelov napovedovanja splošnega cvetenja domače češplje in bobovca smo uporabili metodi korelacijske analize in linearno multiplo regresijo. Rezultati linearne multiple regresije kažejo, da lahko za napoved splošnega cvetenja vseh treh sadnih rastlin s pridom uporabimo podatke o pojavu prvih listov pri brezi (R2 je od 0.61 do 0.91).

Podatki o pojavu prvih listov pri bukvi so uporabni tudi za napovedovanje splošnega cvetenja hruške in jablane (R2 je od 0,62 do 0.66). Poleg tega obstaja statistično značilna zveza med pojavom splošnega cvetenja tako pri bobovcu kot pri domači češplji s kombinacijo povprečne marčevske in aprilske temperature zraka, pri hruški pa s kombinacijo povprečne februarske in marčevske temperature zraka. V primeru napovedovanja splošnega cvetenja bobovca lahko s takšnim modelom razložimo 76 % variabilnosti podatkov v primeru splošnega cvetenja domače češplje pa 55 %. Napovedovanje splošnega cvetenja bobovca na podlagi povprečne temperature zraka marca in aprila je možno v povprečju le dva dni vnaprej, pri cvetenju domače češplje pa še manj. Povezave pojava splošnega cvetenja bobovca in domače češplje s količino padavin v spomladanskem času niso statistično značilne. To lahko razložimo s tem, da v pomladanskem času količina padavin v zadostuje potrebam rastlin. Analize fenoloških podatkov, ki so predstavljene v članku, kažejo na to, da lahko za napovedovanje pojava fenofaz sadnega drevja uporabimo različne klimatološke podatke ter fenološke podatke samoniklih rastlin.

Dunja BANDELJ, Jernej JAKŠE, Branka JAVORNIK

 

ABSTRACT

RAPD markers were applied to assess molecular polymorphisms within olive cultivars held in a collection orchard and to develop a system of a minimum number of primers for cultivar identification. Random Amplified Polymorphic DNA of fifteen cultivars ('Istrska belica', 'Štorta', 'Buga', 'Črnica', ‘Unknown 2’, 'Leccino', 'Nocelara del belice', 'Frantoio', 'Cipressino', 'Santa Caterina', 'Pendolino', 'Arbequina', 'Maurino', 'Picholine', 'Unknown 1') was analysed, using twelve different arbitrary primers: OPA-1, OPA-4, OPA-8, OPX-2, OPX-3, OPX-4, OPX-8, OPX-11, OPX-12, OPX-13, OPX-14, OPX-19. The results confirmed identity within trees of thirteen cultivars in the collection orchard while mislabeling was found in two cultivars. The high polymorphism detected by RAPD markers was successfully used for the development of an identification key for rapid olive cultivar determination.

IDENTIFIKACIJA KULTIVARJEV OLJK (Olea europaea L.) Z MOLEKULSKIMI MARKERJI

Za vrednotenje molekulskega polimorfizma znotraj kultivarjev oljk, zbranih v kolekcijskem nasadu smo uporabili RAPD markerje in razvili sistem minimalnega števila začetnih oligonukleotidov potrebnih za identifikacijo kultivarjev. Z dvanajstimi različnimi začetnimi oligonukleotidi: OPA-1, OPA-4, OPA-8, OPX-2, OPX-3, OPX-4, OPX-8, OPX-11, OPX-12, OPX-13, OPX-14, OPX-19 smo analizirali naključno namnoženo polimorfno DNK petnajstih kultivarjev ('Istrska belica', 'Štorta', 'Buga', 'Črnica', ‘Neznana 2’, 'Leccino', 'Nocelara del belice', 'Frantoio', 'Cipressino', 'Santa Caterina', 'Pendolino', 'Arbequina', 'Maurino', 'Picholine', 'Neznana 1'). Rezultati so potrdili identičnost med drevesi znotraj trinajstih kultivarjev v kolekcijskem nasadu, pri dveh kultivarjih pa smo odkrili napačno označitev nekaterih dreves. Visok polimorfizem odkrit z naključno namnoženo polimorfno DNK lahko uspešno uporabimo za razvoj ključa za hitro identifikacijo kultivarjev oljk.

Evaluation of clonal variability of cv. Refošk

(Vitis vinifera L.) by ampelographic parameters and microsatellite analysis

Petra KOZJAK, Zora KOROŠEC-KORUZA, Irma TOMAŽIČ, Jernej JAKŠE, Branka JAVORNIK

ABSTRACT

Twenty - one clone candidates or elites from the basic collection in the Kras winegrowing district of cv. Refošk, were studied in order to assess their genetic and morphological variability. Morphological variability was evaluated with 71 phyllometric variables or 30 less environment dependent variables, which were then used in cluster analysis. Both resultant dendrograms combined the majority of elites into closely related groups, except elite 50, which did not group with any of the analyzed elites. Microsatellites were used for the assessment of genetic variability among elites. The allelic profile at 5 microsatellite loci (VVS2, VVS4, VVMD6, VVMD7 and VVMD8) was identical for 20 elites, while elite 50 showed an unique allelic profile at all analyzed loci. Microsatellite analysis was proven to be relatively fast and simple, providing reliable results in comparison with well established ampelography. However, a combination of both methods was found useful in evaluation of variability among elites, especially when clones are phenotypically heterogenous and of unknown genetic origin, as in the case of the cv. Refošk basic collection.

PROUČEVANJE VARIABILNOSTI KLONOV cv. 'Refošk' (Vitis vinifera L.) Z AMPELOGRAFSKIMI PARAMETRI IN MIKROSATELITI

Proučevali smo genetsko in morfološko variabilnost 21 klonskih kandidatov oziroma elit cv. 'Refošk' s Kraškega vinorodnega okoliša. Morfološko variabilnost smo ocenili z metodo združevanja v skupine na podlagi 71 ampelografskih spremenljivk oziroma na podlagi 30 izbranih spremenljivk, za katere smo menili, da so od okolja manj odvisne. V obeh dendrogramih je večina elit združenih v skupine, ki se med seboj ločijo s kratkimi evklidskimi razdaljami, izjema pri tem je elita 50. Genetsko variabilnost smo analizirali z mikrosatelitnimi markerji. Pri 20 elitah je bil alelni profil na 5 proučevanih lokusih (VVS2, VVS4, VVMD6, VVMD7 in VVMD8) enak, za elito 50 pa je značilen svojevrsten alelni profil. Proučevanje genetske variabilnosti z mikrosateliti je v primerjavi z ustaljenimi ampelografskimi metodami dokaj hitro, enostavno in zanesljivo. Kljub temu je kombinacija obeh metod zelo uporabna pri proučevanju variabilnosti med elitami, še posebej v primeru fenotipsko raznolikih elit, pri katerih ni znan genetski izvor.

ABSTRACT

ANALYSIS THE POSSIBILITIES OF MARKETING ORGANIC PRODUCTS IN THE NORTH - EASTERN PART OF SLOVENIA (Celje region)


An opinion poll survey was carried out to analyse the possibilities of marketing organic products in the north – eastern part of Slovenia (Celje region). The survey included 250 randomly selected customers. On the basis of the results from the questionnaire about the customers’ profiles, purchasing motives and information management, an example of a marketing strategy is given. The results of the survey show that the customers are well acquainted with organic farming. In their opinion, fresh, healthy and tasteful food is the strongest motive for them to buy it. More than 50% of the customers, when buying food, require information about the origin of food and the methods of food production, and 88% of them would be willing to purchase food directly from food producers. A majority of the customers would also be prepared to pay higher prices for organic food. This work was supported by the Research Support Scheme of the Open Society Support Foundation, grant No.:108/1998.

Gregor UREK, Simon LAPAJNE

ABSTRACT

In frame of annual sanitary field inspection and in accordance with the existing legal rules, soil samples were taken in 1999 and inspected for the presence of potato and other cyst forming nematodes. A total of 133 fields with the surface of 371 hectares were inspected. Cysts of yellow potato cyst nematode, Globodera rostochiensis (Woll., 1923) Behrens, 1975, were extracted from samples taken in 1.6 hectare field in the area of the village of Libeliče, the region of Koroška, near the Slovene-Austrian border. Based on this find, an additional, more accurate (net sampling) soil sampling was performed on 10 hectares of fields from which 206 soil samples were taken. Potato nematode cysts were discovered in 48 samples taken from 3 neighbouring fields. A total of 1449 cysts of potato nematode were extracted, 1309 in the first field, 139 in the second and one in the third.

POJAV KROMPIRJEVE OGORČICE, GLOBODERA ROSTOCHIENSIS (WOLL., 1923) BEHRENS, 1975 V SLOVENIJI

V sklopu vsakoletnega zdravstvenega pregleda njiv smo v letu 1999 v skladu z obstoječimi zakonskimi predpisi odvzeli vzorce tal in jih pregledali na navzočnost krompirjevih in drugih cistotvornih ogorčic. Skupno smo pregledali 133 njiv v izmeri 371 ha. V vzorcih 1.6 hektarske njive z območja Libelič na Koroškem, blizu slovensko avstrijske meje, smo izločili ciste rumene krompirjeve ogorčice, Globodera rostochiensis (Woll., 1923) Behrens, 1975. Na temelju te najdbe smo v začetku leta 2000 na tej in desetih sosednjih njivah opravili naknadno, natančnejše (mrežno) vzorčenje tal, v sklopu katerega smo obdelali 10 ha njiv, s katerih smo pobrali skupno 206 vzorcev tal. Ciste krompirjeve ogorčice smo odkrili v 48 vzorcih tal odvzetih s treh stikajočih njiv. Izločili smo skupno 1449 cist krompirjeve ogorčice in sicer s prve njive 1309, z druge 139 in s tretje eno. Glavnina cist je bila izločena iz enega, okoli 200 m2 velikega otoka na prvi njivi.

IZVLEČEK

V raziskavi smo ugotavljali kako se ljudje odzivajo na rastline, ki rastejo v njihovem bivalnem okolju, na prostem. Osnovne odgovore na vprašanja, ki smo si jih zastavili, smo dobili z anketiranjem. 70 udeležencev ankete je odgovarjalo na vprašalnik, ki je bil sestavljen v obliki semantičnega diferenciala (SD). S tem merskim inštrumentom smo ugotavljali razlike med doživljanjem različnih drevesnih vrst. Semantični diferencial je sestavljalo 13 sedem stopenjskih lestvic, presojanih drevesnih vrst je bilo 12. Udeleženci so vseh 12 drevesnih vrst doživljali pomembno različno in sicer so razlike nastopile pri vseh lestvicah SD. Na osnovi odgovorov anketirancev so bili izdelani polarizacijski profili za vsako drevesno vrsto posebej. Največje razlike v doživljanju presojanih vrst so nastopile takrat, ko so se zdele rastline udeležencem: umetne, neznane, urejene in neobičajne. Glede na te lastnosti sta se oblikovala dva sklopa rastlin: v prvega spadajo vrste, za katere so te lastnosti tipične (povešajoča sofora, kroglasti javor, rdečelistna bukev – pomladni videz, cigarar in srebrna smreka) in v drugega tiste, za katere te lastnosti niso pomembne (breza, dob, platana, alepski bor, vrba žalujka, laški topol, rdečelistna bukev – jesenski videz).

ABSTRACT

WAYS OF EXPERIENCING DIFFERENT TREE SPECIES

This study examines people's response to the outdoor ornamental plant. Basic research data have been obtained from interviews. A questionnaire in the form of semantic differential was answered by 70 respondents. With these measure instrument we investigated the differences between participants experience of 12 different tree species. Semantic differential was made from 13 7-point scales. Respondents experienced all 12 tree species significantly different on all the 13 polar scales. On the basis of the respondent answers semantic profiles for each tree species were elaborated. The greatest differences between trees were perceived when trees appears artificial, unknown, regular and unusual. Regarding these properties two groups of plants were formed: trees which these properties are typical of belong into one group (Sophora japonica 'Pendula', Acer platanoides 'Globosum', Fagus sylvatica 'Atropunicea' in the spring, Catalpa bignonioides and Picea pungens 'Kosteri') and in the other group trees for which these properties have no importance ( Betula pendula, Platanus x acerifolia, Pinus halepensis, Salix sepulcralis 'Chrysocoma', Populus nigra 'Italica', Fagus sylvatica 'Atropunicea in autumn).

Abstract

This study focused on operational procedure of water allocation across a public irrigation system in Indonesia. The objective is at achieving goals of water distribution in the attempt to gain both equity and efficiency. Methodology of this study is conducted through a series observation on the field that have implemented Pasten, Faktor-K, Faktor Palawija Relative (FPR) and Golongan methods as the step of water allocation procedures. Results of the study showed that these methods were carried out harmonically amongst the irrigated area according to the characteristic of its land and availability of water. There are no overlapping or varying of the methods using in each block. However, it was found some violations of operational rules due to lack of irrigation inspectors, malfunction of measurement structure, miss in assessing areas by crop type and planting date, and many tertiary blocks across more than one village.

An analysis on food consumption of households

classified by income in rural China

Linhai MEI

Abstract

In the paper analyzes influences on food consumption by households classified by income in rural China. The income-food consumption relationships (Engel functions) are estimated and income (demand) elasticities for food consumption are analyzed. The results display that income elasticity for grain has been very different among various income groups; for the most prosperous group, grain goods has become into abnormal goods, but for other groups grain goods are all normal goods. Decline of income elasticities meat by year imply stable meat consumption so that meat has become necessaries. Income elasticities for luxury foods both by year and by across section has been very higher, and their very higher R2 values mean the change in consumption of luxury foods depends strongly on income change. That is, Chinese rural households will continue to expend expenditure share in luxury foods as income increases.

Key words: income (demand) elasticity, income groups, food consumption, rural China.

ANALIZA POTROŠNJE HRANE V GOSPODINJSTVIH, GLEDE NA DOHODKE V RURALNIH OBMOČJIH KITAJSKE

Avtorji so v ruralnih območjih Kitajske raziskali potrošnjo hrane glede na višino dohodka gospodinjstva. Ocenjen je odnos med dohodkom gospodinjstva in potrošnjo hrane (Englove krivulje), analizirana pa je tudi dohodkovna elastičnost potrošnje hrane. Rezultati so pokazali visoko variabilnost dohodkovne elastičnosti potrošnje žit med različnimi dohodkovnimi skupinami gospodinjstev; v najbolj premožnih gospodinjstvih so žita inferiorna dobrina, v vseh drugih pa normalna. Zniževanje dohodkovne elastičnosti v opazovanem obdobju kaže na stabilno potrošnjo mesa, ki ga uvršča med nujno potrebne dobrine. Dohodkovna elastičnost potrošnje luksuznih dobrin je bila visoka tako med leti kot med skupinami. Visoka vrednost R2 kaže, da so spremembe v potrošnji luksuznih dobrin zelo odvisne od spremembe dohodka gospodinjstva. Tako se lahko pričakuje, da bodo gospodinjstva na ruralnih območjih Kitajske z večanjem dohodka gospodinjstva povečevala delež izdatkov za luksuzno hrano.
