查询词典 survival rate

When intermittent time of subculture was about 20 days, high survival rate and low browning rate was achieved.

4探索了不同取材时期及继代培养间隔时间对嫁接接合部组织的影响。

The results indicated that the best induce medium for bud propagation was B5 + 0.1 mg/L NAA + 3 mg/L 6-BA. The numbers of hormone and nutritious and the period cultured were different in different varieties. The garlic shoot-tip with some bud scale is better for culturing. It can increased the survival rate of virus eliminating seedling and propagate rate.

结果表明，最佳诱导培养基为B5+0.1mg/L NAA+3mg/L 6-BA，但是，激素、营养物质的添加数量以及培养时期不同品种间有差异；剥离大蒜茎尖带一定数量的鳞片为好，其不仅可提高脱毒苗成活率，而且有利于扩大茎尖繁殖系数。

The results showed that NAA at low concentrations 0.1~0.2 mgL^(-1 was more beneficial for root induction, the rate of rooting was up to 100%. 1/4MS was more suitable to deal with the plantlet rooting and form small bulb. The optimal ratio of IBA and AC for rooting was 2.0 mgL^(-1) IBA+0.1%AC. The in vitro growth of plantlets were the strongest, and survival rate was 100% after incubating at 4℃ for 4 weeks when the diameter of bulblet was ≥9 mm.

结果显示；低浓度的NAA0.1~02mgL^(-1有利于根的诱导；生根率均达100%；大量元素1/4MS处理更适合试管苗的生根和小鳞茎形成；"IBA+AC"处理最佳组合是2.0mgL^(-1) IBA+0.1%AC；鳞茎直径≥9mm的试管苗去顶4℃低温冷藏4周；移栽后喷施1/2MS营养液；长势最好；成活率达到100%。

In dentation line group, 3,5 years survival rate was 83.6%,74.4% respectively, and the local recurrence rate was 4.8%.

齿状线组：3年、5年生存率为83.6%、74.4%，局部复发率4.8 %；0～2 cm组：3年、5年生存率为84.6%、72.1%，局部复发率7.7 %。

综合分析认为：YJ 2 0 0 0菌株对家蚕不仅低毒，而且对其生长发育、结茧和生殖力等均无明显的不良影响。

The experimental results showed that adding 20～30mg/L oxytetracycline to the culture medium reduced the pollution rate by more than 25 percentage point and the survival rate increased by more than 10 percentage point.9 kinds of bacteria and 19 kinds of fungus were isolated from the infectious microbes,in which Enterobacterium,Mucor and Alte...

结果表明，在白网纹草初代培养基中加入20～30 mg/L的土霉素，污染率降低25个百分点以上，成活率则提高10个百分点以上。对杂菌分离培养共发现细菌9种，真菌19种，其中肠杆菌、毛霉和交链孢霉是主要的污染菌。

Results: The values of parameters of the rate of biting human, the index of human-blood, the habbit of biting human, the ratio of multiparous mosquitoes, the gonotrophic cycle, the survival rate of every day, the expected life-span, the reproductive time of sporop...
