And the conditions in cell suspension culture of Mikania micrantha were studied. The results showed that sucrose was the compatible carbon sucrose, and 30g/L sucrose concentration can satisfy the growth of Mikania micrantha cell; ammonium was absorbed under different sucrose concentration that haven't demonstrated significant specificity, and was completely absorbed on the lag phase and the early logarithmic phase; while nitrate was mainly absorbed on logarithmic phase. The density-dependent of Mikania micrantha cell starting to grow and density-inhibited of cell growth were proposed, the fittest inoculating quantity of Mikania micrantha in cell suspension culture was 40g/L.
并对微甘菊细胞悬浮培养条件进行研究,结果表明,微甘菊细胞生长适宜的碳源是蔗糖,并且较合适的蔗糖浓度为30g/L;在不同蔗糖浓度下氨基氮的吸收差别不大,氨基氮在迟滞期和对数期前期已基本消耗完毕,对数期生长主要利用硝基氮,因而提出,在微甘菊细胞液体悬浮培养中,氮源可以采用初始低氨基氮浓度,对数期中间维持高硝基氮,而且对数期中逐步流加少量的氨基氮;微甘菊细胞迟滞期分裂启动存在密度依赖现象,对数期生长存在密度抑制现象,最适接种量为40g/L。

Result Richards Model and Monodic Quadratic Equation could properly describe grain dry matter growing process and the change process of grain filling rate with days after anthesis. There was big difference in average grain filling rate, maximum grain filling rate under different planting density. Average grain filling rate 1.26 mg/ and maximum grain filling rate 2.44 mg/ of T7 were the quickest, and the average grain filling rate 0.94 mg/ and maximum grain filling rate 1.99 mg/ of T12 were the slowest, and the maximum difference percentage of the average grain filling rate and maximum grain filling rate among different density were 33.98%, 22.61%. There was significant correlation between average grain filling rate, maximum grain filling rate, grain filling active duration, rapid increasing stage and thousand grain weight, and the correlation coefficients were 0.628*, 0.630*, 0.849**, 0.739**. Active grain filling duration contributed mostly to TGW.
