Abstract: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.
