OXIDATIVE STRESS AND SEED GERMINATION OF WINTER WHEAT (TRITICUM AESTIWUM L.)
Journal Title: Наукові доповіді НУБіП України - Year 2017, Vol 3, Issue 3
Abstract
The intensity of lipid peroxidation of caryopsis, roots and sprouts of winter wheat and its effect on seed germination and seedling growth were studied. Two years of seed storage decrease its vitality, adversely affecting germination qualities. Sterilization of seeds causes an additional chemical stress, which can be regulated by plant growth regulators (PGR) with antioxidant properties. Anti-stress PGRs are able to reduce the negative impact of prolonged oxidative stress caused by protectants and chemicals during sterilization, especially during heterotrophic type of nutrition. Adaptation of primary roots and sprouts to the conditions of caryopsis germination proceeds differently. In roots it ends with transition to autotrophic nutrition, and sprouts - goes to the stage of formation of the first unfolded leaf regardless of the effect of investigated stress factors. In general, the intensity of oxidative stress in sprouts is double as that in the roots. A strong inverse correlation dependence (r = - 0.908 ÷ - 0.997) was determined between malondialdehyde (MDA) and dry matter content in the roots, which should be considered when choosing a combination of protectants and PGR.
