摘  要:
对不同施肥处理下的华北驼绒藜胚胎发育及营养动态进行了研究,结果表明:处理4(尿素60g/株,浇水,喷施0.05%硼酸钠)和处理7(尿素60g/株,浇水,喷施0.05%钼酸氨)为最佳施肥方案,结实率分别达到93%和94%,显著高于对照(87%,86%);增施微量元素硼和钼,结实率比单独施用大量元素有一定提高,但差异未达到显著水平;处理4和处理7可以促进胚胎发育速度,以处理7发育最快,完整胚分化时间为18~21d;营养成分与结实率相关分析表明,N素含量与种子结实率达到显著或极显著相关,主要表现在胚胎发育的中后期(球形胚以后)。

摘  要:
Embryo development and nutrient dynamics of Ceratoides arborescens in different fertilization treatment were studied.The results showed that treatment 4(urea 60g/ individual,watering,0.05% sodium borate) and treatment 7(urea 60g/ individual,watering,0.05% ammonium) were the best fertilization program,the seed setting rate was enhanced to 93% and 94%,respectively;the seed setting rate after application of the trace elements boron and molybdenum was higher than that of macroelements,but the difference was not remarkable.The embryo development speed of the treatment 4 and treatment 7 were faster than control,the embryo development speed of treatment 7 was the fastest,its mature embryo differentiation time was 18~21 days.The N content was significant or extremely significant correlated with seed setting rate,mainly in the mid and late period of embryonic development.
