Some morphological and anatomical observations during alleviation of salinity (NaCl) stress on seed germination and seedling growth of barley by polyamines

Warianty tytułu

Języki publikacji



In this work, the effects of polyamine (cadaverine, putrescine, spermidine, spermine) pretreatments on the germination of barley seeds, seedling growth under saline (NaCI) conditions and on leaf anatomy of the seedlings grown for 20 days in pots with perlite containing different concentrations of NaCI prepared with Hoagland solutions following the germination period of 7 days were studied. The inhibitive effect of salt on seed germination and seedling growth was alleviated in varying degrees, and dramatically, by polyamine pretreatments at the levels of NaCI studied; particularly with lower levels of salt, the control seeds were able to germinate with great difficulty. Also, the successes of these pretreatments continued, even decreased, with higher levels of NaCI such that the control seeds showed no germination. On the other hand, on the various parameters of leaf anatomy of barley seedlings, interactions between pretreatments of polyamine and salinity, with some of these being statistically important, were observed.
