Effects of Cyanamide Treatments on Budding, Flowering and Fruit Quality of Kyoho Grape

In order to clarify the optimum dosages of cyanamide in grape production,the effects of different dosages of cyanamide treatments on the germination rate, flower formation rate and fruit quality of grapes were studied in grape cultivars ‘Kyoho’ in Tongan, Xiamen.The results showed that the germination rate was not significantly affected by the low dosage of cyanamide, and the high dose treatment could result in partial bud damage. 4.00% of the treatment had the best germination effect. At the same time, different dosages of cyanamide treatment had no significant effect on the rate of flowering and the fruit quality of Kyoho grape.
