Corn seedling sensitivity on stress conditions

Abstract

Corn seed has different tolerance on effects of different stress conditions. It was tested influence of salt concentration (NaCl) increasing in substratum and drought tolerance on the corn seedling length (PEG). For the salt tolerance it was used 7 different concentrations of NaCl and for drought tolerance 4 different concentration of PEG. The study shows what kind of influence has salt and drought stress on decreasing on length of corn seedling. The study shows the level of concentrations salt and drought stress has negatively influence on length of corn seedling and also how corn seedling is resistance on this stress. .

Seme kukuruza osetljivo je na pojedine stresne uslove koji se javljaju u prirodi. Ispitivan je uticaj povećanog sadržaja soli (primena NaCl) u supstratu, odnosno uticaj suše na dužinu klijanca kukuruza (primenom PEG-a). Za osetljivost na sušu upotrebljene su 4 različite koncentracije PEG-a, dok za osetljivost na prisustvo soli u supstratu 7 koncentracija NaCl-a. Zaključuje se da suša i povećan sadržaj soli utiču na smanjenje dužine korena i dužine stabaoceta klijanca. Testovi su pokazali koje su to koncentracije koje imaju negativan uticaj na porast klice i koliko je ona otporna na njih. Takođe istraživanje je pokazalo da ispitivano seme može podneti određene stresne uslove. .
