摘要本文研究了为小蜜蜂授粉的蜜蜂种类,以及它们的生长和衰退规律。
Through analysing, we attempt to know the degrading omethoate bacteria's development of seasonal growth and decline in this ecosystem.通过分析试图了解这一生态系统中降解有机磷农药氧乐果细菌的季节消长动态。
Combining cell morphology, the growth and decline state of tapetum in anther wall tissue are closely related with pollen fertility and amino acid metabolism.结合细胞形态学观察,药壁组织的绒毡层的发育与解体状况和花粉育性、氨基酸代谢有着密切关系。
