GA3 is used to promote the germination of barley seeds, which plays a role in saving grain, reducing cost, shortening production cycle and ensuring beer quality.
Maize plants treated with high concentrations of gibberellin (500 ~ 1000ppm) can result in partial or complete male sterility.
This is very beneficial to the breeding of maize inbred hybrids.
Under low temperature and low light, gibberellin can break the dormancy of herbage, which is beneficial to green manure cultivation.
In summer drought or low temperature, can promote the growth of sugarcane;
Under the low temperature in early spring, it can promote the early germination of peas and string beans, and the rapid emergence of seedlings.
Gibberellin is commonly used in agriculture to improve the yield of seedless grapes, break the dormancy of potatoes, and promote tassel in hybrid rice seed production to improve the yield of hybrid seeds.
