| 摘 要： | 目的]为木兰属植物资源的合理开发及利用提供科学参考。方法]以玉兰、紫玉兰和荷花玉兰3种常见木兰属园林乔木为研究对象，通过测定其成株叶片的长、宽、面积及生物量，分析其叶片的表型可塑性和生长规律。结果]3种植物均具有较大的表型可塑性。叶生物量的变异系数最大，为35．45％～57．50％。叶面积变异系数次之，为34．72％～48．44％。叶长、叶宽的变异系数均较小，为18．77％～28．28％。玉兰与荷花玉兰的叶宽与叶长呈幂函数异速生长规律，而紫玉兰呈直线同速生长；玉兰、紫玉兰的叶生物量与叶面积呈直线同速生长规律，而荷花玉兰呈幂函数异速生长。结论]玉兰、紫玉兰和荷花玉兰3种成株叶片在叶长、叶宽、叶面积以及叶生物量等数量性状均具有较大的表型可塑性。

| Abstract: | Objective] The research aimed to provide scientific reference for the reasonable development and utilization of Magnolia plant resources. Method] Taking three common Magnolia garden arbor species Magnolia denudate, Magnolia liliflora, Magnolia grandiflora as research objects, the phenotypic plasticity and the growth regulation of the leaves were analyzed through the measurement of the leaf length, breadth, area and biomass of the adult plants. Result] The three plants all have the phenotypic plasticity o... |
