Physiological and Biochemical Effects of High Temperature Stress on the Seedlings of Two Rhododendron Species of Subgenus Hymenanthes
高温胁迫对两种常绿杜鹃亚属植物幼苗生理生化特性的影响

To illuminate the injury mechanism of Rhododendron Subgenus Hymenanthes under high temperature stress,4-year-old seedlings of R.simiarum Hance and R.jinggangshanicum Tam were planted in artificial climate chambers and their physiological and biochemical changes were determined under different high temperature stress.The results showed that:(1)The contents of malondialdehyde(MDA),hydrogen peroxide(H2O2),proline(Pro)and soluble protein in leaves of both species increased when the temperature increased.The con...
