Control Gender Differentiation in chestnuts
Application of regulators for controlling Gender Differentiation in chestnuts
Gibberellic acid
Treatment with 50-100 mg/L gibberellic acid could significantly increase the female flower differentiation rate of chestnut and decrease the ratio of male flower to feminization.
6-benzylamino-purine 6BA
Treatment with 100 mg/L 6-BA could significantly increase the differentiation rate of chestnut female flowers and reduce the ratio of male and female flowers.
Forchlorfenuron CPPU
Treating chestnut seedlings with 1 mg/L chlorfenuron + 1000 mg/L paclobutrazol not only significantly increased flower bud differentiation and the number of female flower clusters, but also promoted 40% of seedlings to flower and bear fruit at least 1 year earlier than the control.
Penicillin
After chestnut germination, the use of 100-150 mg/L penicillin can improve the ammonia metabolism level and photosynthetic intensity of the tree, and significantly promote the differentiation of female flowers and the thickening of new shoots.
Ethephon
Ethephon has the effect of promoting androgen at low concentration and inhibiting male flower at high concentration. At 50 mg/L, it can significantly increase male flower clusters, and at 100 mg/L and 200 mg/L, it can significantly inhibit male flowers.
