In this experiment, the growth status and flower bud differentiation of blueberry plants were studied after pruning the second or third buds at the top of the sprouting branches in the northern highbush blueberry cultivar ‘Brigitta’ in southwestern China. The results showed that there was no significant change in the content of ethylene among the five endogenous hormones, but top pruning had a significant effect on the content of the other four hormones, which indicated that top pruning could affect flower bud differentiation by regulating the content of endogenous hormones. The number of florets per panicle was significantly increased, which signified more fruits per panicle, and increased fruit yield.
