摘要
中国沙棘(Hippophae rhamnoides L.Subsp sinensis Rousi)是个遗传结构十分复杂的种群。树型、棘刺、果色、果形、果实大小、种子大小等,均有幅度很大的变异,尚未从种群表型结构角度系统研究。为了探明中国沙棘种质资源状况,了解各种性状变异的幅度和性质,以及性状变异之间的关系,1988年秋,对甘肃省榆中县兴隆山自然保护区的中国沙棘天然林,从表型上对其种群结构作了系统调查和分析,为探索中国沙棘的种群分化和演进,为在生产上对中国沙棘进行遗传调控和育种提供资料。
The investigation of basic information on germplasm resource of Hippophae rhamnoides in China has important significance.In the autumn of 1988,the character variations of Hippophae rhamnoides and their correlation hadbeen investigated in Xinglongshan Nature Reserve in Gansu province, e. g.tree shap, branching ability, number of thorns, length and width of leaves,leaf density, fruit color, fruit shap, fruit diameter, weight per 100 fruitsin fresh, weight per 1000 kernels of seed. Main parameters of various variationtime-space structure and the multiformity of Hippophae rhamnoides populationin Xinglogshan Nature Reserve were discribed.
