山西省关帝山中国沙棘种群表型结构的研究*

Study on the Population Phenotype Structure of Chinese Hippophae in Guandishan, Shanxi Province

  • 摘要: 1989年秋季,用样地调查和统计分析方法,研究了分布于山西省关帝山寨则沟地区的中国沙棘的树型、发枝力、棘刺、果色、果形、果实重量等性状的变异,探讨了主要经济性状间的相关关系和各主要性状的组配情况、分布形式和种群表型结构特征.指明关帝山的中国沙棘,是以主干型桔黄色、近圆果形植株为主体的多态型种群系统.百果重值较大,产果量较丰,可作为生态经济型造林用种的候选采种基地之一.

     

    Abstract: In the autumn of 1989, plot investigation and statistics analysis were used to study the variation of tree type, branching ability, thorn, fruit color, fruit shape, fruit weight etc. features of the Chinese Hippophae in Chaizhuogou Region, Guandishan, Shanxi Province. The interrelationship between the economic features and the match condition, distribution type and characteristics of population phenotype structure of the main features have been discussed. The results indicated that the Chinese Hippophae there is mainly a multitype population system, whose plants bear fruits of orange color and are nearly round in shape. Its hundred-fruit weightis is bigger and has a high fruit yield. Guandishan Region can be selected as a candidate base for collecting seeds for eco-economic cultivation.
