Abstract

Abstract: The growth and senescence of GF₄₃( Prunus domestica L. ) cultured at different temperatures in vit ro were studied. The results showed that the growth rate of GF₄₃ plantlet in vitro was slow at 16 ℃, the activities of superoxide dismutase (SOD) , catalase (CAT) and peroxidase ( POD) were incresed , the activated oxygen scarenging system was improved. Consequently this alleviated the harmful effect of O·₂ and reduced the membrane lipid peroxidation in shoot , prolonged the life-spane of GF₄₃ plantlet in vitro.

Key words: Prunus domestica L., Temperature, Plantlet in vitro, Senescence
