干旱胁迫对6个树种叶片光合特性的影响
Effect of drought stress on photosynthetic characteristic of six tree species
摘要
Abstract
Six tree species(Ormosia hosiei Hemsl. Et Wils, Photinia × fraseri ' Red Robin' , Schima superba, Zellcova schneideriana, Salix × jiangsuensis cv. ' J172' , Primus cerasifera ' Hollywood' ) were conducted to compare the difference of photosynthetic characteristic and drought resistance. Results showed that there were great differences of photo-synthetic characteristics of these six tree species during 10 d drought stress period. Photosynthesis of Primus cerasifera ' Hollywood' and Salix jiangsuensis cv. ' J172' were much more sensitive to drought stress, of which there were significant decline of photosynthesis after 10 d drought stress due to stomatal limitation. In Zelkova schneideriana, stomatal limitation appeared after 4 d drought stress, however, the photosynthesis level return to normal level in the 10th day. In contrast, there was no stomatal limitation in Ormosia hosiei Hemsl. Et Wils, Photinia. Fraseri ' Red Robin' and Schima superba during drought stress period. According to the Ci and Ca ratio of six tree species of normal irrigation during the 10 d period, the drought resistant ability arranged in descending order was Ormosia hosiei Hemsl. Et Wils, Schima superba, Zelkova schneideriana, Photinia fraseri 'Red Robin' , Salix jiangsuensis cv. 'J172' , Prunus cerasifera 'Hollywood'.关键词
