Gibberellic acid is a kind of phytohormone with gibberellic alkane ring structure that can promote plant growth. It exists in both free and bound forms. Generally, there are at least two or more Gibberellic acids in plants, and different Gibberellic acids can be transformed into each other. Young tissues of leaves, buds, roots and immature seeds are the main synthesis sites of Gibberellic acid. It has physiological effects such as promoting stem elongation, inducing bolting and flowering of long-day plants under short-day conditions, breaking dormancy, promoting fruit setting and parthenocarpy, and cell division and differentiation. The most significant effect of gibberellins is to promote tissue growth and significantly increase plant height, especially for some genetic dwarf plants.
Application:
1. Improve the yield of three-line hybrid rice seed production: This is a great innovation in hybrid rice seed production in recent years, and it is an important technical measure. For example, Jianhu County, Jiangsu Province has 100,000 mu of breeding fields and seeding fields. It is the national hybrid rice seed production base, and the yield per unit area of gibberellin has been significantly increased. Gibberellins can adjust the flowering period, reduce neck wrapping, promote earing of the parents, increase the exposed rate of stigma, increase the number of effective ears and grains, increase the rate of seed setting, and significantly increase the yield.
2. Promote seed germination. Gibberellin can effectively break the dormancy of seeds and tubers and promote germination. Treating potatoes with 0.5-1 mg/kg gibberellin solution can break dormancy and is suitable for second-season cultivation of potatoes. For some seeds that require low temperature to germinate (such as peach, hazel) or seeds that require red light to germinate (such as some lettuce varieties), treatment with gibberellin can replace low temperature or light conditions to promote germination. Gibberellins are now used in the brewing industry. Treatment of non-malting barley with gibberellin can promote the activity of α-amylase. This can save food and increase beer production.
3. Accelerate growth and increase output. Gibberellic acid GA3 can effectively promote plant stem growth and increase leaf area, thereby increasing yield.
4. Promote flowering. Gibberellic acid GA3 can replace low temperature or light conditions required for flowering.
5. Increase fruit yield. Grapes, apples, pears, jujubes, etc. are sprayed with 10-30ppm GA3 in the young fruit stage, which can increase the fruit setting rate.
