厚荚相思花粉活力测定及贮藏研究

Storing and Viability Testing of Acacia crassicarpa Pollen

开展花粉的活力测定及贮藏研究,对进一步开展相关树种的杂交育种研究具有重要意义。关于厚荚相思(Acacia crassicarpa)的花粉活力测定及贮藏研究,却没有见报道。本试验通过对厚荚相思花粉开展不同活力测定方法的比较、花粉管萌发法的最佳条件的筛选以及花粉贮藏一定时间的活力测定等系列研究,建立了厚荚相思花粉有效的活力测定方法和最佳技术体系,以及有效的贮藏方法,为今后进一步开展厚荚相思的杂交育种以及通过人工控制授粉创制新的育种材料等奠定重要的基础。

It has important significance to study on the pollen viability determination and storage on the cross breeding research for related species.No any reports have been reported about pollen viability determination and storage of Acacia crassicarpa.In this paper,through the comparison of pollen tube method for the determination of optimum conditions,to carry out the different activity of A.crassicarpapollen germination and pollen storage method of screening for a certain period of time the activity series of research,has established the A.crassicarpapollen effective activity determination method and the best technology system,and the effective method of storage,for further development of A.crassicarpahybrid breeding and laid an important foundation by artificial pollination in development of breeding.
