| 摘 要： | 为了研究实生繁殖对早实核桃优良性状的影响情况,以8年生"辽核1号"实生后代为研究对象,对其物候、生长、开花、结实等方面的性状特点及相关指标进行了观察与测定。结果表明:实生后代个体间的性状差异较大,不能保持母树的优良特性。认为选育良种核桃不能走实生繁殖的道路,应以无性繁殖为主要途径,这样才能保持其优良性状。

| Abstract: | In order to study effects of seed propagation on good characters in precocious walnut, taking 8-year-old seedlings in Liaohe No.1 as study objects, traits and some related indexes of phenophase, growth, bloom and bearing were observed and measured. The results showed that individual character differences in the seedlings were obvious, and the good characters in mother tree could not be kept. Therefore, asexual propagation should be the major propagation method instead of seed propagation. |
