THE EFFECT OF DIFFERENT TEMPERATURES AND SALT CONCENTRATIONS ON SOME POPCORN LANDRACES AND HYBRID CORN GENOTYPE GERMINATIONS

Abstract

In this study, five popcorn, which belong to Adıyaman (Adıyaman-1 and Adıyaman-2) and Çanakkale provinces (Çanakkale-1, Çanakkale-2 and Çanakkale-3), and four hybrid corn genotypes (Progen Favorite, Progen 1550, HK Heroic and BC 566) were germinated at two different temperatures (13 and 22ºC) and at four different salt concentrations (0, 25, 50 and 100mM NaCl). The traits, such as germination speed, germination rate, vigor index, radicula length, coleoptile length and plumula length were investigated. The genotypes, different temperatures and salt concentrations were significantly different accordance to investigated traits. The interactions between genotype x salt concentration, genotype x different temperature and among genotype x salt concentration x different temperature were significant according to the some traits. It was recorded that increased temperatures caused an important positive effects on germination traits while increased salt concentrations caused negative effects. Popcorn landraces had higher values than hybrid types in according to investigated traits.
