毛白合的胚培养

为毛百合杂种胚培养选择适宜培养期及培养基。用亲本毛百合进行了胚培养适宜日期及适宜培养基的筛选试验。试验表明毛百合授粉后３９ｄ剥取的胚在ＭＳ附加０．０００１￣０．０１ｍｇ／Ｌ ＮＡＡ的培养基上就可诱导成幼苗。形成胚时间越长，诱导成活率也越高。这为以毛百合为亲本的种间杂交提供了获得杂种胚的方法和依据。

Embryos Culture of Lilium dauricum

In order to select the optimal cultural duration and medium for the culture of hybrid embroys of the L. dauricum , screening experiments on optimal cultural duration and medium were performed using embyos of parents. Results indicated that embryos, stripped on 39 days after pollination and cultured on MS medium supplemented with 0.0001-0.01mg/L NAA, may be induced to produce seedling. The longer the time of formation of embryos is, the higer the percentage of viability of induction. These experiments provided a method and basis for obtaining hybrid embryos after the interspecific hybridization between different species of the L. dauricum .
