摘    要:以沙冷杉为材料,对其结实特性进行观测,结果表明:在城市人工栽培条件下,初次结实年龄为40~45 a,与野生植株基本相同,初次结实株率为31.3%;充足的光照可使结实植株和球果数量增加,温度对其无明显影响.球果着生于2 a或3 a生枝条基部,以2 a生枝条基部居多;多集中分布在树冠上部的枝条上.果鳞开裂至有种子与果鳞脱落...

关 键 词:沙冷杉:结实年龄  球果着生部位  球果成熟期

Abstract:The reproduction characteristics of Abies holophylla were measured.The initial reproduction occurred between 40~45 a under cultivated condition in urban environment.Similar to the wild plant,the initial seed rate was 31.3%.The number of plants reproduced and cones increased with the light intensity,but unrelated with temperature.The cones grew at the base of branches 2 or 3 year-old,more cones at 2-year-old branches which at the upper of canopy.It spent about 5 d from the cone-scale splitting to separating,...
Keywords:Abies holophylla  reproduction age  position of cones  cone maturity period
