Physicochemical properties : white crystalline powder or white prismatic crystalline powder, GA4 melting point is 214 ~ 215 ℃; Ga7 acicular crystal, melting point 169 ~ 172 ℃, prismatic crystal, melting point 202 ℃; Ga4+7 [a4:a7=40:60] the melting point is 198 ~ 202 ℃. It is stable in dry state and relatively stable in weak acidic solution. It is easy to change its structure in case of alkali, and even lose its biological activity

Purpose: biochemical research. Broad spectrum plant growth regulators promote the fruit setting rate of melon and fruit plants or the formation of seedless fruits; Promote the growth of vegetative bodies of leafy vegetable plants; Break the dormancy of plant seeds and promote seed development; Delay the aging of fruits and keep them fresh; Change the proportion of female and male flowers and affect the flowering time; When used in hybrid rice seed production, it can adjust the flowering period, promote the heading of the parent parent, increase the number of effective panicles and grains, and significantly improve the seed setting rate

Storage: 2 ~ 8 ℃
