摘  要:
研究了涂料覆盖和遮阳网覆盖对夏季棚内辣椒幼苗生理指标的影响。结果表明:夏季塑料大棚内的持续高温对辣椒幼苗造成了严重损伤,致使其叶绿素积累减少,根系吸收能力减弱,细胞膜损伤,抗氧化酶系统被破坏,超氧化物歧化酶(SOD)和过氧化物酶(POD)活性减弱;不论是涂料覆盖还是遮阳网覆盖,都能在一定程度上减轻缓解辣椒幼苗的高温伤害,使得辣椒幼苗叶绿素含量升高,MDA含量降低,POD和SOD活性增强;与遮阳网相比,涂料覆盖更有利于幼苗生长。

摘  要:
The physiological indices of pepper seedling in plastic greenhouses were studied byusing coating and shading-nets.The results showed that in no-shading greenhouse,the chlorophyll content and root activity significantly decreased under a high temperature.At the same time,MDA content increased,and SOD activity and POD activity were reduced.Both coating and shading-nets relieved the injury from high temperature to some extent.Chlorophyll content and root activity increased,but MDA content decreased.POD and SOD activity enhanced because of coating.Compared with shading-nets,paint coating could be more beneficial to improve the growth of pepper seedlings.
