旺盛生长

Developmengts anslysis on plant high, caulis leaves and single fruit showed with coincident disciplinarian, but distributing unlikeness. From seedling time to flourishing time, 2 importing varities's developments curve were keeping epigyny, showed that importing tomatoes varities had obvious advantage on plant high, caulis leaves and single fruit, and had bigger increase production potential.

株高、主茎叶片数和单株果数等3个测试指标的动态分析表明，规律一致但分布不同，2个进口品种的动态曲线从苗期到盛果期始终保持上位，说明进口品种在株高、主茎叶片数和单株果数3个生长发育指标上具有明显优势，植株生长旺盛，增产潜力大。

In conclusion, the lag phase of Streptococcus thermophilus was shorten in the eutrophy culture medium, and the time achieving the culminated point of logarithmic phase was shorted also, at the same time, the stationary phase lengthened. After secondary culture, Streptococcus thermophilus reached directly the log phase hardly through the lag phase, and then quickly reached the decline phase. There were more relations of the metabolic regalities of the three kinds of nutritive substances with the super-concentrated incubation process of Streptococcus thermophilus: the more the number of the bacteria, the quicker the metaboling, while the fewer, the slower the metabolism. Moreover, there apparently existed morphologic changes in this course, and there maybe existed the apoptosis, which correlated with bacteria propagation and acid producing. With the culture time postponed, the nutritive substances in the culture medium lacked also, and the morphologic change and apoptosis appeared more obviously.

结果表明，嗜热链球菌在营养丰富的培养基中的生长延滞期缩短，到达对数生长顶点的时间变短，稳定期的时间延长，当经过二次培养后，嗜热链球菌几乎不经过延滞期直接到达对数期，平稳期持续的时间较短，很快到达衰亡期；嗜热链球菌在超浓缩培养过程中三大营养物质的代谢规律也同它的培养过程有很大的关系，菌数多，其代谢旺盛，菌数降低其代谢速度减慢；嗜热链球菌在超浓缩培养过程中存在着明显的菌体形态变化，并可能存在着细胞凋亡，与菌体增殖和产酸规律密切相关，随着培养时间延长，培养基中营养物质变得贫乏，菌体形态变化和细胞凋亡的情况愈加明显。

Help advance somebody's career what what is appropriate to the occasion offers fixed rate is shady, maintain temperature to be in 12, 29 ℃ left and right sides, winter temperature appropriate is maintained in 16, 18 ℃, chun Xia two season grow exuberant, need taller air humidity, can undertake sparge; To soil the requirement does not father very, but the requirement keeps measurable and wet, grow seasonal, about 2 weeks apply fertilizer, and winter soil can work a bit and cool, reduce fertilization number; The method of minute of root is used more when breed; At Chu Xia season undertakes, return the method that can use cuttage additionally; Main pest has powdery flea, red spider, aphid, scale insect to wait.

The results show that the duration of the 3 phases during the culture of cell suspension is related to the inoculum size, the initial nutrient concentration, the feeding of nutrients and the culture conditions such as temperature and dissolved oxygen, that the maximum cell yield reaches about 12g/L for batch culture or 35g/L for fed-batch culture in dry weight, that the saponin content of cells quickly increases in the bloom phase and keeps on increasing until the early stage of the declining phase, with a maximum saponin content of about 60~70g/kg in dry weight, that the conductance value of cell suspension decreases from more than 8000μS to less than 600μS with the growth of cells, but increases when the cells autolyze, and that part of cells turns red in the later culture, which has no apparent effect on the saponin content.

结果显示：细胞3个生长时期的持续时间与接种量、初始营养浓度、营养流加情况及培养条件有关；分批培养和流加培养时的最大细胞得率分别为12g/L和35g/L；细胞的皂甙含量在旺盛生长期快速上升，并保持增长至衰退期前期；干细胞中最大的皂甙含量达60~70g/kg；随着细胞的生长，培养液的电导值从8000μS以上下降至600μS以下，细胞自溶后逐渐回升。另外，培养后期部分细胞颜色变红，但没有发现颜色转变对皂甙含量造成影响。
