为了充分利用我国丰富的丁香资源,培育丁香新品种,我们从1985年开始,持续进行了丁香属的杂交育种工作。同时为了克服杂交胚的败育现象,应用了幼胚培养技术,于1988年初步培育出一年两次开花的新品种——四季兰丁香。但是有的杂交组合,采用一般幼胚培养也未能使其杂交胚发芽成植株。为了解决这个问题,从1988年开始,进行了授粉后不同发育期杂交胚的离体培养及其发芽能力的研究。关于丁香属植物的组织培养,国外报道过欧洲丁香的茎尖培养、丁香的胚培养,国内外尚未见报道。
In order to make full use of our rich clove resources and cultivate new varieties of cloves, we started the crossbreeding work of Syringa genus from 1985 onwards. At the same time, in order to overcome the abortion of hybrid embryos, the immature embryo culture technique was applied. In 1988, a new breed of biennial clover was initially bred. However, some hybrid combinations, the general immature embryo culture also failed to germinate their hybrid embryos into plants. In order to solve this problem, from 1988 onwards, carried out in vitro pollination of embryos at different developmental stages in vitro culture and its ability to study. On the Syringa tissue culture, foreign reports of European clove shoot tip culture, clove embryo culture, at home and abroad have not been reported.
