查询词典 NAA

As regards rooting from clumpy buds, only NAA can induce rooting and NAA 0.5 mg/L is the best hormone concentration, whereas 6-BA has negative effect, and active carbon has no effect in this study.

猜A可使康乃馨愈伤组织分化，添加适量NAA效果更好，6-BA 1.0 mg/L＋NAA 0.5 mg/L和6-BA 2.0 mg/L＋NAA 0.5 mg/L诱导的芽点最多；但6-BA对丛生芽来源的无根苗的生根起抑制作用，活性炭对生根并无帮助，而以NAA 0.5 mg/L的生根效果最佳。

It turned out reproduction rete of chrysanthemum was raised,the regular,non-plant diseases and insect pests could be offered to the market. Shoot tip were used as explants to study the effects of different sterilization methods, illumination intensity and concentrations of 6-BA and NAA on shoot propagation. Rooting with perlite, vermiculite and river sand instead of agar was studied. In the process of preliminary multiplication, the effect of using 0.1% HgCl_2 in sterilization of explants was better than using saturated bleaching solution. The highest multiplication rate was found under whole illumination. MS media with 6-BA from 0.2 mg·L~(-1) to 5 mg·L~(-1) and NAA from 0.05 mg·L~(-1) to 2 mg·L~(-1) were tested and as a result, the highest differentiation rate and the multiplication rate was reached with 0.2 mg·L~(-1) 6-BA, 0.05 mg·L~(-1) NAA.

At the same time ,the cap of filter paper was used for improving transformation ratio. Leaf discs were transferred onto the media MS+ NAA(1mg/L)+6-BA(3mg/L)+Km(30mg/L)for regeneration resistant selction. Shoots from selection medium were cultured on medium MS +NAA(1mg/L)+6-BA(3mg/L)+Km(50mg/L) for selection again,and then on the media 1/2MS+NAA(0.2mg/L)+IBA(0.2mg/L)+Km(25mg/L)for rooting selectin.

Segments produced clusters of somatic embryos from embryogenic calli or directly from root apical meristems , and that also can convert into bud directly in the different tissue culture conditions. Modified media B5 with 1.0 mg.L-1 2,4 - D and 3.0mg.L~1 6-BA is suit to induce calli, and 0.5 mg.L-1 NAA is fit for somatic embryos inducement from calli. 6-BA encreased direct somatic embryogenesis on root tip distinctly,but NAA is retard it. NAA also prolong the time of root-tip convert into bud directly.

在改良B_5(微量元素为原来的1／3)中加入1.0mg.L~(-1)2，4—D和3.0mg.L~(-1)6-BA对离体根尖的愈伤组织诱导较为合适，0.5mg.L~(-1)NAA有利于从愈伤组织上产生体细胞胚；6-BA明显促进离体根尖直接产生类原球茎，而NAA则有阻碍作用；同时NAA的存在也使离体根尖直接成芽的时间延长。
