氨基嘌呤

0Mg/L 6-benzylaminopurine was the optimal concentration of shoots quantity inducing which frequency of inducing shoots and number of shoots per explant were 100% and 11.1 respectively. 0.5mg/L 6-benzylaminopurine was the optimal concentration of shoots length inducing which average length of shoots was 12.0mm. Explant size had significantly effects on direct shoots quantity and length induction. When complete cotyledon used as explant, frequency of inducing shoots, number of shoots per explant and average length of shoots could approach to 100%, 6.7 and 17.1mm respectively. 2.0mg/L silver nitrate could significantly increase shoot quantity induction, both frequency of inducing shoots and number of shoots per explant could be as high as 97.2% and 4.2 respectively. But silver nitrate also could restrain shoots elongation.

The variance of ABA of grape during storage were discussed in this paper.The following results are been drawn:the change of the content of ABA of grapes during storage characterizes by a parabolic shaped curve with obvious peak.Low temperature (0±0.5℃) is conducive to delaying the appearance of the peak of ABA and reduces the peak value.Nine kinds of plant growth regulators and two kinds of chemicals were chosen to treat grape bunches so as to study their mechanisms on ABA of grapes,2,3,5 triiodobenzoic a...

试验研究了葡萄贮期脱落酸的变化，结果表明：葡萄贮期 ABA含量呈抛物线形变化，有明显的高峰出现，低温( 0± 0 。5℃)贮藏具有推迟 ABA峰期和降低峰值的作用，经用 9种植物生长调节剂和 2种化学药品对葡萄果穗处理试验，三碘苯甲酸对 ABA的形成有极强的抑制作用，吲哚- 3-乙酸、赤霉素( GA3)、萘乙酸和 6-苄基氨基嘌呤( 6- BA)对 ABA的形成也具有拮抗作用，矮壮素、比久( B9)、乙烯利和外源脱落酸对 ABA的形成有促进作用。
