干旱对烤烟光合特性的影响研究
Research on Influence of Drought Stress on Photosynthetic Characteristics of Flue-cured Tobacco
摘要
Abstract
The potted flue-cured tobacco varieties Yunyan 87 and K326 were used as test materials,drought stress treatments for different time(0~16 d)were conducted respectively at their resetting stage,vigorous growing stage and squaring stage,and the influence of drought stress on the photosynthetic characteristics of flue-cured tobacco was studied. When drought stress time pro-longed,the stomatal conductance,transpiration rate,and net photosynthetic rate of two varieties all showed a decreased tendency, while their intercellular CO2 concentration decreased significantly and then increased slightly. As drought treatment time increased, the chlorophyll content in Yunyan 87 revealed a declining trend,while that in K326 reduced first and then rose. After being influ-enced by drought stress,Yunyan 87 had a slightly better general performance in photosynthetic characteristics than K326.关键词
