Abstract
Cilj rada bio je ispitati utjecaj suše inducirane polietilen glikolom 6000 u laboratorijskim uvjetima u koncentracijama od 0 %, 6 % i 12 % na klijavost ječma, odnosno energiju klijanja, ukupno klijanje, broj korijena, dužinu korijena, dužinu koleoptile te masu svježih i suhih klijanaca ječma. Analizom varijance utvrđeno je da polietilen glikol uglavnom nema statistički značajan utjecaj na rast i razvoj klijanaca, osim za energiju klijanja i masu svježe tvari. Prosječne vrijednosti u ovom istarživanju su bile 80,9 % za energiju klijanja, 96,2 % za ukupno klijanje, 4,49 za broj korijena, 5,02 cm za dužinu korijena, 1,20 cm za dužinu izdanka, 5,05 g za masu svježe tvari i 2,01 g za masu suhe tvari klijanaca ječma. Primjena (PEG-a) pri nižoj koncentraciji rezultirala je približno sličnim vrijednostima kao i kod kontrolnog tretmana dok je veća koncentracija imala za posljedicu izraženije negativne razlike. Pretpostavka je kako bi daljnje povećanje koncentracije (PEG-a) rezultiralo i većim negativnim utjecajem na rast i razvoj klijanaca ječma.
Abstract (english)
The aim of the thesis was to examine the impact of drought induced by polyethylene glycol 6000 in laboratory conditions in concentrations of 0 %, 6 % and 12 % on barley germination, i.e. germination energy, total germination, number of roots, root length, coleoptile length and weight of fresh and dry barley seedlings. Analysis of variance determined that polyethylene glycol generally has no statistically significant effect on the growth and development of seedlings, except for germination energy and mass of fresh matter. Average values in this study were 80.9 % for germination energy, 96.2 % for total germination, 4.49 for number of roots, 5.02 cm for root length, 1.20 cm for shoot length, 5.05 g for the mass of fresh matter and 2.01 g for the mass of dry matter of barley seedlings. Application of (PEG) at a lower concentration resulted in approximately similar values as in the control treatment, while a higher concentration resulted in more pronounced negative differences. The assumption is that a further increase in (PEG) concentration would result in a greater negative impact on the growth and development of barley seedlings.
