【摘要】 高山红景天 (RhodiolasachalinensisA .Bor.)根、茎、叶中均有发达的通气组织 ,根中的通气组织是维管射线细胞破裂形成的。根中任何薄壁组织细胞中均含有固体蛋白质。茎中维管束环外有糊粉层。叶肉细胞中的固体蛋白质多数存在于叶脉周围。植物体内丰富的蛋白质构成了其较强抗冻能力的物质基础。根中木栓十分发达更多还原

【Abstract】 There are a lot of aerenchyma in the roots,stems and leaves of Rhodiola sachalinensis. The aerenchyma was made of broken cell of vascular ray in the roots.The solid protein exists in all of the parenchyma of the roots. There is the aleurone layer outside the bundle ring of the stems .The solid protein exits most the round of the vine. Abundant protein of the plant is formed the very strong antifreeze material basis. the phellem is very expand in the secondary structure of the root.更多还原
