对栽培大麦×野生大麦杂交的胚胎发育情况进行了观察,结果如下:栽培大麦与野生大麦的种间杂交可交配性很差,多数子房均未受精,少数子房中观察到虽然能受精,但极不正常,受精延迟而且不完整,仅发生卵的单受精,并且发育中途停止,在众多制片中末发现有胚乳发育,也未发现胚的进一步分化和成熟。说明栽培大麦与野生大麦杂交存在合子前和合子后面的困难,讨论了这些困难产生的可能原因,并认为引起合子后困难的主要原因可能是因为不能形成胚乳,因此认为通过杂种胚的离体培养可在一定程度上克服合子后发育困难,而能获得杂种植株。
The results showed that the interspecific hybridization between cultivated barley and wild barley was poorly crossed, most of the ovary were not fertilized, while in the few ovaries, although the embryos could be fertilized, But extremely abnormal. The fertilization was delayed and incomplete. Only single fertilization of eggs took place and the development stopped midway. Endosperm development was not found in many productions, and no further differentiation and maturation of embryos was found. The results showed that the difficulties existed after the hybridization between cultivated barley and wild barley existed before and after the zygotes. The possible reasons for these difficulties were discussed. The main reason for the difficulty in posterior zygotes was probably that the endosperm could not be formed. Therefore, To a certain extent, overcome the difficulties of zygotic development, but can get hybrid plants.
