Dinamika rasti in rodnosti enoletnih poganjkov oreha sorte \u27Elit\u27
An architectural analysis of a fruiting branch in the Slovenian variety \u27Elit\u27 was conducted during three successive years. The fruit bearing branch was constructed of a three-year-old parent shoot plus all corresponding two-year-old shoots and annual shoots (1Y). The construction of the bearing branch during the time caused a statistically significant increase in the number of annual shoots. The basal diameter and the length of 1Y significantly depended on a year whereas their angles did not. In spite of decreasing length of 1Y, the number of vegetative buds per shoot increased from the first to the third year of observations. The number of nodes was closely correlated with the length of the shoots. Activity points on the 1Y were most often on the apical two or three nodes, what was expressed by a marked acrotony. The number of active points varied as the tree matured. The ratio fruit bearing 1Y ž total 1Y was 0.47 in year 10.18 in year 20.74 in year 3. It points to the slightly alternance. As the tree grew the number of flowering buds per 1Y as well as the number of female flowers per 1Y increased. The results of the three-year-long research show some growth and development rules in the walnut cultivar \u27Elit\u27, however, they do not allow a reliable prediction of the following activities. We assume that this will be possible after another three-year-long analysis, with the help of the Hidden Mark Model.Da bi proučili dinamiko rasti in rodnosti enoletnih poganjkov pri slovenski sorti oreha \u27Elit\u27, smo v treh zaporednih letih izvedli arhitektonsko analizo rodne veje, zgrajene iz triletnega nosilnega poganjka in vseh pripadajočih dveletnih in enoletnih poganjkov (1Y). Z izgradnjo rodne veje se je iz leta v leto statistično značilno povečevalo število 1Y. Leto je značilno vplivalo na bazalno debelino in dolžino 1Y, na njihove kote pa ne. Čeprav se je dolžina 1Y zmanjševala od prvega do tretjega leta opazovanj, je število vegetativnih brstov na 1Y naraščalo. Število nodijev je bilo v vseh letih v tesni zvezi z dolžino poganjkov. Aktivna mesta na 1Y so bila najpogosteje na zadnjih dveh ali treh nodijih, kar se odraza v izraziti akrotoni razrasti. Število aktivnih mest se je povečevalo s starostjo drevesa. Razmerje skupni 1Y/rodni 1Y je bilo v prvem letu 0.47, v drugem letu 0.18, v tretjem letu pa 0.74 in nakazuje rahlo izmenično rodnost. Z leti sta naraščali število rodnih brstov in število zenskih cvetov na 1Y. Triletni rezultati nakazujejo nekatere zakonitosti v rasti in razvoju oreha sorte \u27Elit\u27, ne dopuščajo pa še zanesljivega napovedovanja nadaljnje aktivnosti. Ocenjujemo, da bo s pomočjo Markove verige to mogoče po opravljenih analizah v naslednjem triletnem ciklusu
