摘 要：
对准噶尔盆地6个不同生境梭梭[Haloxylon ammodendron(C.A.Mey)Bunge]种群植株生长状况与种子产量之间的关系进行了比较。结果表明,植株形态参数冠幅(C)、基径(D)、高度(H)与种子产量(M)之间存在紧密的相关关系。通径分析结果显示,冠幅对植株种子产量的影响最大,其后依次为高度、基径。试验建立的梭梭种子产量预测方程为:M=178.572+3.47×10-5 CH-1.106 H-0.007 C(R=0.830,P<0.01)。

摘 要：
In order to study the seed production situations and predicating the seed yield of Haloxylon ammodendron(C.A.Mey) Bunge, the relationships between seed yield and plant growing parameters of 6 populations in different habitats were studied in Junggar basin. Correlation analysis indicated that seed yield(M) had high and positive correlations with crown(C),basal diameter(D) and height(H). Path coefficient analysis showed that crown had the maximal and positive direct effect on seed yield, followed by height and diameter. Finally, established H. ammodendron seed yield prediction model is M=178.572+3.47×10-5CH-1.106 H-0.007 C(R=0.830,P<0.01).
