By random arrangement of three densities and different hurt level in the bud period,the test imitated compensative ability of Long-staple Cotton after injury in order to help the management of harmed cotton.
试验设置3种密度,随机区组排列,模拟长绒棉蕾期不同程度损害时所具有的产量补偿能力,结果表明,在同一密度下,棉株损害越轻,产量补偿能力越大;受害重的棉株前期恢复生长较快,但对后期的产量补偿力作用较小;在不同的损害程度下,随着密度的增加棉株产量补偿能力减小。
Besides foliar symptoms,some physiological indexes such as chlorophyll,Catalase (CAT),peroxidase (POD),malondialdehyde (MDA),soluble sugar content,solu.
对马尾松幼苗的外部受害症状进行观察记录,测定其叶片的叶绿素含量、过氧化氢酶活性(CAT)、过氧化物酶活性(POD)、丙二醛含量(MDA)、可溶性糖和可溶性蛋白质含量等生理指标。
