Morphological and anatomical characteristics of phyllotaxy of Antirrhinum majus
摘要
Abstract
In this paper,paraffin method has been used to make the morphological and anatomical observation of terminal buds on different nodes ofAntirrhinum majus caulis during development.The result shows that the growth cones located from the 1-6th nodes of the caulis of Antirrhinum majus will develop to opposite leaf primordiums and become decussate opposite phyllotaxis.The shape of the leaves varies from ovate to oval.24.4％ of growth cones located on the 7th node will develop to opposite leaf primordiums and become opposite phyllotaxis.The other 75.6％ will develop to alternate leaf primordiums on one side and become alternate phyllotaxis.On the 8th node,84.0％ of growth cones will develop to alternate leaf primordiums and become alternate phyllotaxis.From the 9th node,all of the growth cones will develop to alternate leaf primordium on one side and become alternate phyllotaxis.The leaf will turn to long and narrow lanceolate shape.This means the 7-8th nodes of Antirrhinum majus caulis are the nodes where the phyllotaxis changes from opposite to alternate.From 13th node (no later than 17th),the terminal bud of caulis may stop apical growth and becomes flower bud.There is no flower bud in opposite phyllotaxis.After the terminal bud of caulis turning to flower bud,the lateral branches will also develop as the caulis.The lateral buds will turn to flower buds and blossom one after another.关键词
