黄化现象
etiolation

   多数植物在黑暗中生长时呈现黄色和其他变态特征的现象。植物在暗中不能合成叶绿素,显现出类胡萝卜素的黄色;节间伸长很快;叶片不能充分展开和生长;根系、维管束和机械组织不发达。
   在黄化幼苗的叶肉细胞中存在着很小的无色质体——原质体。原质体在照光后叶绿素才开始形成和累积,并发育成叶绿体进行光合作用。很弱的光就能消除幼苗的黄化现象,使叶片展开并变绿,恢复正常生长。这种作用通过光敏素发生,与光合作用通过叶绿素进行完全不同。黄化现象是植物对环境的一种适应。当种子或其他延存器官在无光的土层下萌发时,可使贮存量有限的有机营养物质最有效地用于胚轴或茎的伸长,保证幼苗出土见光。
