摘要
以江浙地区自然栽培的披针叶八角成年植株为材料,对其表型遗传多样性进行调查与分析的结果表明,披针叶八角植物在树形与枝叶形态、叶芽萌发与开花时期、花器官色泽与形状、结实性及抗逆性等方面均存在显著差异,而结实性差异既受植物遗传结构主因的影响,也因产地生境条件的不同而变化。披针叶八角植物显示的丰富遗传多样性为其园林绿化应用提供了更多的品种选择和环境安全性。
Phenotype diversity of Illicium laceolatum was analyzed and investigated with natural cultivated adult plants in Jiangsu - Zhejiang area to select new type of lllicium laceolatum for city gardening. The results showed that obvious differences among lllicium laceolatum plants existed in morphology of trees and branches, date of budding and flowering, stress resistance and so on. Different fruitfulness were mainly influenced by genetic structure and also varied with different cultivated environment. Abundant genetic diversity of Illicium laceolatum plants should supply more varietal selection and environment safety for their application in gardening.
