高温强光胁迫是影响我国花生产量的主要因素之一，高温强光下花生吸收的光能来不及耗散，由光激发产生的多余电子就会通过Mehler反应传到02产生活性氧在光合器官积累，而活性氧积累很容易对光系统造成伤害。有研究表明钙离子可以缓解环境胁迫对植物的伤害。

Role and interrelationship of Ga protein, hydrogen peroxide and nitric oxide in UV-B-induced stomata
We found that 0.5 W m-2 UV-B triggered a significant increase in hydrogen peroxide (H2O2) or nitric oxide (NO) levels associated with stomatal closure in wild type, but these effects were abolished in
