大多数豆科植物具有不透水的硬实种子,具有物理休眠.种子休眠特征和休眠释放机制与物种保护和物种更新有直接关系.本研究通过对14种豆科植物种子进行吸水试验鉴定种子的物理休眠.对具有物理休眠的种子进行机械划破、浓硫酸处理、不同温度(模拟自然环境的极端高温)和不同时间的干湿处理,研究种皮对种子休眠释放和萌发的影响,探讨种子物理休眠在干旱环境下的释放机制.

由于具有较高的pH值和盐度,苏打型盐碱土对大多数植物的生长具有一定的胁迫作用.利用透射电子显微镜技术对生长在苏打型盐碱土和中性土壤的紫丁香叶片叶绿体的超微结构及其内含物进行了比较研究.结果表明,在苏打型盐碱土生长的紫丁香叶片内,部分叶绿体被破坏,功能叶绿体被膜轻微膨胀,叶绿体内出现两种不同电子密度的脂质球;相对于中性土壤生长的紫丁香叶绿体,苏打型盐碱土胁迫的叶绿体内积累了更多的淀粉粒.
