Pridelek in kakovost jajčevca (Solanum melongena L.) v odvisnosti od neposrednega prekrivanja

Kušar, Špela (author), Kacjan Maršić, Nina (mentor)

Poskus smo izvedli z namenom, da ugotovimo učinek neposrednega prekrivanja po presajanju sadik jajčevca (Solanum melongena L.) na prosto na količino in kakovost plodov. Poskus je bil izveden na Laboratorijskem polju Biotehniške fakultete v Ljubljani in je potekal od aprila do oktobra 2018. V poskus smo vključili pet različnih sort. Od tega so bile tri hibridne sorte ('Galline F1', 'Black beauty F1' in 'Black bell F1') in dve nehibridni sorti ('Violetta di Rimmini' in 'Domači srednje dolgi'). Za vsako sorto smo posadili 40 rastlin. Od tega smo 20 sadik prekrili za 21 dni s polipropilensko prekrivko, ostale rastline pa so bile neprekrite. Poskus je bil sestavljen iz petih ponovitev, vsako ponovitev so predstavljale 4 rastline. V rastni dobi smo imeli 6 obiranj. Pobirati smo začeli 27. junija in končali 11. oktobra. Pobrane plodove smo prešteli, stehtali in izmerili višino, širino ter maso. Prekrivanje je povečalo pridelek le pri dveh sortah, pri 'Domači srednje dolgi' za 9 % ter pri sorti 'Black beauty F1' za 12 %. Pridelek ostalih treh sort je bil pri neprekritih rastlinah večji glede na prekrite rastline. Največji pridelek so dale neprekrite rastline sorte 'Galline F1' (49 t/ha), najmanjši pa neprekrite rastline sorte 'Domači srednje dolgi' (7 t/ha). Prekrivanje rastlin je imelo pozitiven učinek na kakovost plodov le pri sorti 'Galline F1', kjer so bili plodovi prekritih rastlin 25 % težji od plodov neprekritih rastlin. Tudi pri sorti 'Black beauty F1' so bili plodovi prekritih rastlin 6 % težji glede na neprekrite rastline.

• Title: Yield and fruit quality of eggplant (Solanum melongena L.) in relation to direct cover

Abstract

The experiment was conducted to determine the effect of direct cover after transplanting eggplant (Solanum melongena L.) seedlings in the field on fruit quantity and quality. The trial was conducted on the Laboratory Field of Biotechnical Faculty in Ljubljana and lasted from April to October 2018. Five different cultivars were included in the trial. Three of them were hybrids ('Galline F1', 'Black beauty F1' and 'Black bell F1') and two non-hybrids ('Violetta di Rimmini' and 'Domači srednje dolgi'). Forty plants were planted for each cultivar. Of these, 20 seedlings were covered with polypropylene cover for 21 days and the remaining plants were not covered. The experiment consisted of five replicates, each replicate consisting of 4 plants. We had 6 harvests during the growing period. We started harvesting on 27 June and finished on 11 October. Harvested fruits were counted, weighed, and height, width, and weight were measured. Covering increased yield only for two cultivars, for 'Domači srednje dolgi' 9%, for 'Black beauty F1' 12%. The yield of the other three cultivars was higher in uncovered plants than in covered plants. The highest yield was produced by uncovered plants of 'Galline F1' (49 t/ha), the lowest by uncovered plants of 'Domači srednje dolgi' (7 t/ha). Covering the plants had a positive effect on fruit quality only for the variety 'Galline F1'. The fruits of the covered plants were 25% heavier than the fruits of the uncovered plants. Also for the variety 'Black beauty F1' the fruits of the covered plants were 6 % heavier than those of the uncovered plants.
