外源水杨酸(SA)与甜菜碱(GB)对干旱胁迫下辣椒开花结果期光合特性的影响
|
摘要
以"云椒2号"为试材,采用盆栽控水法,研究外源水杨酸(SA,200mg·L~(-1))和甜菜碱(GB,100mmol·L~(-1))对干旱胁迫下辣椒开花结果期光合生理特性的影响。结果表明:在干旱胁迫下,外源GB、SA处理的辣椒叶片净光合速率(Pn)、蒸腾速率(Tr)、气孔导度(Gs)和胞间CO_2浓度(Ci)有明显增高,各处理的日平均净光合速率值为GB>SA>干旱。通过相关分析得出净光合速率与环境影响因子的关系,干旱胁迫下,净光合速率与气孔导度呈正相关,而外源GB、SA处理的净光合速率与气孔导度、蒸腾作用呈正相关。
The purpose of this study was to explore the effects of exogenous salicylic acid(SA,200mg·L~(-1))and glycine betaine(GB,100mmol·L~(-1))on physiological characters of‘Yunjiao 2’of hot pepper(Capsicum annuum L.)under drought stress during blossom and fruit period by the water controlable pot planting.The results showed that under the condition of drought stress,exogenous GB and SA could effectively enhance the net photosynthesis rate(Pn),transpiration rate(Tr),stomatal conductance(Gs)and the intercellular CO_2concentration(Ci),the daily average net photosynthetic rate were GB>SA>drought.Through correlation analysis showed that the relationship of net photosynthesis rate with the environmental factors,net photosynthesis rate was positively correlated with stomatal conductance,while net photosynthesis rate was positively correlated with stomatal conductance and transpiration rate by exogenous GB and SA treatments under drought stress.
