杂种落叶松花器官发育过程研究
Studies on the development of reproductive organs of hybrid larch
落叶松的良种供应受限于种子园产量的不稳定,通过施肥、激素处理及树体管理等措施种子产量得到一定提高,但未从根本上解决产量低、结实不稳定的情况。因此需要对落叶松的成花机理进行研究,从而提高良种产量和稳定性。以杂种落叶松二代种子园为材料,通过花期花量观测、形态解剖、激素测定、转录测序、外源激素处理等手段,结合生殖芽形成到传粉全过程中形态水平、细胞水平、生理水平、基因表达水平的特征对杂种落叶松开花生物学特性,花器官发育过程和成花诱导机理进行了研究,为种子…查看全部>>
The supply of improved varieties of larch is limited by the instability of seed orchard yield.The seed yield could be improved through fertilization,hormone treatment,tree management and other measures,but the situation of low yield and unstable seed setting has not been fundamentally solved.Therefore,it is necessary to study the flowering mechanism of larch,so as to improve the yield and stability of improved varieties.With the second generation seed orchar…查看全部>>
