    摘要:

    莲叶有三种形式:沉水叶无气孔;浮水叶气孔仅分布于腹面;挺水叶形大、气孔数多。器官中气室和气道发达。排水器位于叶腹面的中央,除常敞开着外,与气孔相似,水分可从此排出。莲具有星散的维管束、无形成层,只在根中有导管,胚根简化,不定根发达。花早期发育在水中,后由柄生长延伸出水面。果实中具有三个功能不同的孔。果皮上的表皮层及栅状细胞层发达。

    Abstract:

    There are three distinct types of leaves: the submerged leaves, which are sto-mateless; the floating leaves, with stomata generally confined to the upper surface 5 the aerial leaves are usually large, with numerous stomata.The rhizomes are creeping, with numerous branches. By means of these branches,the rhizomes spread rapidly through the mud. Parts of the rhizome become fleshy tubers, which serve for vegetative propagation of the plant.The air chambers and passages are well developed in all the organs.The ...
