It is used to stimulate the nourishment growth in leafy vegetables like spinach.

It is able to break the dormancy of seeds such as potato and ginseng, and promote seed development. Gibberlin also helps to defer the decrepitude of fruits and therefore to prolong the freshness.

It is able to change the proportion of female and male flowers, and blossoming time also.

When used for hybrid rice seed growing, gibberellic acid can adjust blossoming period and promote the spike growing of the parents. This will in turn increase the valid spike counts and grain counts with obviously increased burliness rate.


lettuce 10-25 spraying 2-3 times when it has 13-14 leafs increase production
