Inducing loquat seedlessness
Application of regulators inducing loquat seedlessness
Gibberellic acid GA3
In the flowering stage (early October), spray 500 mg/L gibberellic acid on the leaves for seedless induction, combined with spraying 10-20 mg/L chlorfenuron in three times during the young fruit and fruit expansion stage (January to April). In order to increase the fruit and improve the quality, the seedless fruit rate can reach 100%, and the edible and commercial property of loquat can be significantly improved. (Note: After only using gibberellic acid to induce seedless fruit, without cytokinin for later expansion, the fruit will be seriously small and fall off. This is due to the lack of fertilization and the lack of hormone-producing seeds in the fruit, which leads to attracting photosynthetic products. The ability is weak, which will ultimately affect the growth and sugar accumulation of seedless loquat fruit, resulting in small fruit and falling off. Therefore, in order to ensure the normal growth and development of seedless fruit and maintain the original fruit quality, it is necessary to use clopyridine after inducing the seedless fruit. Urea to increase the level of fruit hormones and enlarge the seedless fruit.)
