Comparative Anatomy Studies on Leaves and Petals of Nelumbo
The comparative anatomy of the leaves and petals of Nelumbo species was studied.The results were as follows,the leaves of Nelumbo species all have the palisade tissues and the spongy tissues,but the thickness and percentage of palisade tissues and spongy tissues were different.The crystals of calcium oxalate were often found in mesophyll cells.The minute projections were found on both sides of epidermal cells of petals.There were only very loose spongy tissues and not palisade tissues existing in Nelumbo petals.There were few differentiations in anatomy of leaves and petals not only between N.nucifera and N.lutea,but also between the tropic origins and the temperate origins.The results suggested that lotus showed the adaptation to the aquatic environment in its anatomic characters of leaves and petals,and the interspecific and intraspecific differentiations were not obvious.
