Potassium nitrate and ethephon were sprayed on 7- year-old Guifei trees out of season. The results showed that AP1 gene had a higher expression level in terminal buds, and especially, the expression level increased significantly in late stage of flower bud differentiation. Potassium nitrate and ethephon promoted flower bud differentiation, and the expression level of AP1 gene in- creased in flowering process remarkably. Expression ofAP1 gene of the potassium nitrate treatment was significantly greater than that of the ethephon treatment and the CK.展开更多
