摘要
本文从叶片含水量、水势、蒸腾作用及土壤含水量等方面综合阐述了裸子植物在干旱胁迫下的水分代谢活动,鉴于植物的各种代谢活动相互影响,需综合多因素共同探讨植物的抗旱机制,以期为裸子植物的抗旱资源选育提供一定理论依据。
The metabolic activities of water under draught stress are summarized regarding water content,water potential,transpiration and soil water content.The physiological metabolisms are influenced by activities of each other and it is necessary to investigate the drought resistant mechanisms of gymnosperms through the integrated approach.
