Abstract
[Objective]This study aimed to investigate the regulatory effect of 6-Benzylaminopurine(6-BA)on the sprouting of lateral branches in central leader-trained Prunus simonii×P.armeniaca.[Methods]Using three-year-old Prunus simonii×P.armeniaca trees as experimental material,treatments with 0,400,600,and 800 mg·L-1 6-BA were de-signed.Key indicators,including the number of sprouted lateral branches and the growth increment of the central leader and lateral branches,were measured.[Results]The results showed that treatments with 400 and 600 mg·L-1 6-BA significant-ly promoted the sprouting of lateral branches,increasing it by 9.1 to 12 times compared to the CK.In contrast,the 800 mg·L-1 treatment exhibited a marginal effect.In the treatment groups,the growth inhibition rate of the central leader reached 12.4%to 16.1%,and the growth increment of lateral branches decreased by 24.8%to 36.2%.[Conclusion]Comprehensive analysis revealed that 600 mg·L-1 6-BA,while ensuring an effective number of branches(12 per plant),achieved a balance between the growth of the central leader(79.1 cm)and lateral branches(34.8 cm),making it the ideal concentration for con-structing the central leader form in Prunus simonii×P.armeniaca.关键词
