2个枸杞新品种叶片解剖结构比较研究

摘要

The anatomical structures of leaves of 2 new varieties in wolfberry were comparatively studied. The results showed that the leaf thinckness of Ningqi No.6 and Ningqi No.8 were bigger than the Ningqi No.1 ,the cell of upper epidermis and cuticle was thick. The two new verieties were all bifacial leaf,palisade mesophyll which was made up by 2~4 layers was well developed,and showed cells short,tightly packed,more chloroplast in it. But there was quite large intercellular spaces among spongy tissue ,vascular tissue was well developed and these were the basis of two new varieties of medlar vigorous growth and large fruit.%对枸杞新品种宁杞6号、宁杞8号的叶片解剖结构进行了比较，结果表明宁杞6号、宁杞8号的叶片均较宁杞1号厚，表皮和角质层都比较厚。宁杞6号、宁杞8号都属于异面叶，叶肉栅栏组织较发达，通常由2~4层细胞组成，细胞短小，排列紧密，内部富含叶绿素，胞间隙大，维管组织发达，是这2个枸杞新品种生长旺盛、果实较大的基础依据。
