The effect of location, time of collecting and previous treatment on germination ability of the gentiana seed

Abstract

Results of the laboratory study of the germination ability of gentiana seed collected from two locations (Zlatibor and South Kučaj) during two periods (15.07.2005 and 24.08.2005) were analyzed. The effect of cooling (90 days on 40C) and moistening and cooling (90 days on 40C) on germination energy (EK) and total germination (UK) of seed was observed. Location had significant effect on germination energy and total germination. Seed collected from location on Zlatibor had significantly higher germination energy and total germination. Time of collecting also had significant effect on germination ability of the seed (EK and UK). Moistening and cooling of seed had significant effect, seed that was moistened and cooled had higher germination energy and total germination, regardless of the location and time of collecting, compared to seed which was only cooled, and especially compared to not cooled seed (control). Cooled seed had better germination energy and total germination than the control material.

Analizirani su rezultati laboratorijskog ispitivanja klijavosti semena lincure sakupljenog sa dva lokaliteta (Zlatibor i Južni Kučaj) u dva perioda (15.07.2005. i 24.08.2005). Posmatran je uticaj hlađenja (90 dana na 40C) i kvašenja i hlađenja (90 dana na 40C) na energiju klijanja (EK) i ukupno klijanje (UK) semena. Lokalitet je ispoljio značajan uticaj na energiju klijanja i ukupnu klijavost. Seme sakupljeno sa lokaliteta Zlatibor imalo je znatno veću energiju klijanja i ukupno klijanje. Vreme sakupljanja semena takođe je ispoljilo značajan uticaj na klijavost semena (EK i UK). Kvašenje i hlađenje semena imalo je znatan uticaj, pa je takvo seme imalo veću energiju klijanja i ukupnu klijavost, bez obzira na lokalitet i vreme sakupljanja, u odnosu na seme koje je samo hlađeno, i naročito u odnosu na nehlađeno seme (kontrolu). Hlađeno seme imalo je energiju klijanja i ukupnu klijavost bolju u odnosu na kontrolni materijal.
