【摘要】 遮荫后蒜香藤(Pseudocalymma alliaceum)植株增高、节间缩短、叶绿素含量、叶绿素a／b 比值升高,叶片及栅栏组织和海绵组织厚度降低,叶片组织结构紧密度CTR值升高、叶片组织结构疏松度SR降低。更多还原

【Abstract】 The effects of shading on plant growth and leaf microstructure of Pseudocalymma alli-aceum were studied. The results showed that height of the plant, chlorophyll content, chlorophyll a/b ratio and the leaf tissue structure tense ratio (CTR) increased, however,length of intemode,thickness of leaf, palisade tissue and spongy tissue and the tissue structure loose ratio (SR) decreased.更多还原
