Abstract

Za uspješno klijanje povrtnih kultura bitni čimbenici su voda, temperatura i svjetlost. Uslijed
nemogućnosti ostvarenja optimalnih vrijednosti ovih abiotskih čimbenika, kao i pojave
dormantnosti sjemena, često dolazi do odgađanja procesa klijanja. Cilj ovog rada bio je
utvrditi kako predsjetveni tretmani (močenje sjemena u destiliranoj vodi, kupka kamilice,
hladna stratifikacija, preparat ´Ekobooster 1´, kontrola - netretirano) uz dvije konstantne
temperature (15°C, 20°C) utječu na klijavost sjemena luka vlasca. Utvrđeno je da kod
naklijavanja sjemena pri temperaturi 15°C predsjetveni tretman hladne stratifikacije (sjeme
izloženo temperaturi 4oC tijekom 14 dana prije naklijavanja) rezultira najvećom energijom
klijanja i ukupnom klijavošću (76,7 i 95,0%). Kod naklijavanja sjemena pri temperaturi 20°C
niti jedan predtretman sjemena nije rezultirao statistički opravdano većom klijavošću, iako je
netretirano sjeme i ono u tretmanu kupkom kamilice imalo relativno najveću klijavost (91,67 i
86,67%).

Abstract (english)

The effects of temperature, duration of light and amount of water are the most important
factors which need to be accomplished for properly seed germination of vegetable species.
Because of improper accomplish of these abiotic factors and dormancy, some species can be
delayed in their germination. The aim of this work is to determine the best effects of different
sowing treatments on germination of chives (rinse of seeds in distilled water, rinse of seeds in
chamomile, cold stratification, application of ´Ekobooster 1´, and untreated seeds) at two
temperatures (15°C and 20°C). The treatment of cold stratification showed the best results in
tracking the vigor of germination and total germination (76,7%, 95,00%) at 15°C. In addition
to that there was no sowing treatments at 20°C which can show economical approvation.
Untreated seeds and the seeds which were sown in chamomile showed relatively the biggest
total germination at 20°C (91,67%, 86,67%).
