Grape seedless treatment: (1) Using gibberellin 1mg/L and agricultural streptomycin 2mg/L, dipping the flower spike five days before flowering can make the seedless rate reach more than 9%, and the fruit ripens early and the soluble solids increase.

(2) Kyoho grape was sprayed with gibberellin 1 mg/L 12-14 days before blooming, and sprayed again 1 days after blooming.

(3) For Kyoho varieties, the inflorescence was dipped with 25 mg/L gibberellin at full bloom stage, and then the ear was treated with the same concentration once after 1 ~ 15 days. The seedless rate reached 97%, the maturity was advanced by 15 ~ 2 days, and the soluble solids increased by 2% ~ 3%.

(4) Soak the inflorescence and ear with 5 ~ 1mg/L gibberellin once each at full flowering stage and 11 ~ 14 days after full flowering.

(5) Kyoho strain was treated with 1-25mg/L gibberellin and 15mg/L chlorophenoxyacetic acid solution for the first time from the full flowering period to 3-4 days after flowering, and then treated with 25mg/L gibberellin for the second time in 1-15 days. Can be nuclear-free; But also can reduce the ear shaft hardening.
