auxin GREGMAT

1.Auxins influence the growth of stems toward light (phototropism) and against the force of gravity (geotropism).

它可影响茎向光性和背性生。

2.It is the factors affected plant regeneration in explant culture in Euphorbia pulchrrima willd to different explants or aurin or cytokinin or the combination of the auxin and cytokinin.

外植体类型、植物生素、细胞分裂素类型及二者不同组合均红在离体条件下植株再生具有影响。

3.They work antagonistically with ABSCISIC ACID, and in some situations work cooperativedly with AUXINS as, for example, in the control of sex expression in dioecious plants.

例如，在雌雄异株植物中控制性别表达。

4.The results showed that the internodal length and plant height of alfalfa increased with the auxin content increasing,but the internode number didn′t change obviously.

结果表明,随喷施浓度增加,紫花苜蓿节间距和株高增加,但节间数变化不大;

5.The result showed that the successful rooting system was closely related to the concentration of macronutrient of MS medium, auxin concentration and developing state of the explant.

结果表明，培养基中无机盐浓度、外源激素水平、种类以及外植体发育状况等试管嫩茎生根具有明显影响。
