以新疆天山山脉从西到东不同经度3个地点(昭苏、天池和奇台)的天山云杉林为对象,沿海拔梯度采集不同地点的天山云杉球果,分析其种子性状(种鳞长、种鳞宽、种鳞长宽比、种翅长、种翅宽、种翅长宽比、种子长、种子宽和种子长宽比)的变化.结果表明:随海拔的升高,天山云杉种子性状(种子宽除外)总体呈现下降的趋势;除种翅宽、种子宽和种子长宽比与海拔的相关性不显著外,种子其他性状与海拔均呈显著负相关;种鳞长、种鳞宽、种鳞长宽比与经度呈现显著正相关;种鳞长、种鳞长宽比、种翅长宽比与坡度呈显著负相关;除种翅宽外,种子其他性状与坡向相关性均不显著.海拔是影响天山云杉种子的种鳞长、种鳞长宽比和种翅长宽比的主要因子.
The Tianshan spruce plantations in three locations (Zhaosu, Tianchi and Qitai) from west to east in Xinjiang Tianshan Mountains were taken as the objects. The spruce cones were collected from different sites along the altitudinal gradient, and their seed traits (seed scales The results showed that with the elevation increasing, the Tianshan Mountains, the Tianshan Mountains and the Tianshan Mountains, Except seed width, seed width and seed aspect ratio were not significantly related to altitude, the other traits of seed had a significant negative correlation with altitude (P <0.05) , Seedling width and seedling length-width ratio had a significant positive correlation with longitude. Seed length, seedling’s length-width ratio, seed-fin length-width ratio had significant negative correlation with slope degree. But the correlation was not significant.The altitude was the main factor that affected the seed length, the aspect ratio and the aspect ratio of spruce in Tianshan Mountains.
