THE EFFECTS OF DROUGHT ON PLANTS AND TOLERANCE MECHANISMS

Abstract

ABSTRACT

Drought stress, one of the most common environmental limitations affecting growth and productivity of plants, causes many metabolic, mechanic and oxidative changes in plants. Drought induces a diverse set of physiological, biochemical and molecular responses in plants, which provide the ability of adaptation to limited environmental conditions, depending on intensity and periods of stress, interactive effects of the other stress types, development stage and genotype of plants.

Keywords

• Key Words: Drought stress, metabolic, mechanic and oxidative changes, tolerance mechanisms

BİTKİLERDE KURAKLIK STRESİNİN ETKİLERİ VE DAYANIKLILIK MEKANİZMALARI (Derleme)

Abstract

Bitkilerde, büyümeyi ve verimi etkileyen en yaygın çevresel streslerden biri olan kuraklık stresi, metabolik, mekanik ve oksidatif birçok değişikliğe neden olmaktadır. Kuraklık; stresin şiddetine, süresine, diğer stres türleri ile etkileşimlerine, strese maruz kalan bitkinin genotipine ve gelişim basamağına bağlı olarak, bitkilerde sınırlı çevresel koşullara adapte olmayı sağlayacak birçok fizyolojik, biyokimyasal ve moleküler cevabı indüklemektedir

Keywords

• Kuraklık stresi, metabolik, mekanik ve oksidatif değişikler, dayanıklılık mekanizmaları
