摘要
采用引进种子和结果苗木相结合的方法,对各沙棘种及亚种的生物学特性进行了观察,并以省内种质资源丰富且已大量开发利用的中国沙棘为主要研究对象,系统地选育出了长势旺盛、果实性状良好的五个优良家系和三十三个优良单株。
The seeds and fruiting trees of Sea buckthorn (Hippophae) were int-roduced, and the biological characteristics of 4 species and 3 subspecies were observed. Among them, H. rhamnoides L. subsp. sinensis Rousi was mainly studied which has rich natural resiurces and has been extensively exploited and used in Gansu province. We systematically selected and breeded 5 good strains and 33 good individual trees of H. rhamnoides L. subsp. sinensis Rousi which growed vigorously and had good fruit characters.
