6-Benzylaminopurine(6-BA) promote apple seedling branch effect demonstration

Dwarf densely planted apple seedlings in modern orchards have strong apical advantage, which means fruit trees still mainly grow the top branches and the endogenous hormone levels in the lateral buds keep a low level. This will cause the seedlings planted to pull out the top branch, it is difficult to pull out the fruit branch. Apple seedlings with good branching status not only bear fruit branches, but also are more likely to form ideal tree shape, so that the orchard can achieve premature and high yield to obtain better economic benefits.

In September 2021, the Crop Technology Department of Zhengshi Chemical Industry carried out the apple seedling branching experiment in the biochemical tests room and orchard of Henan Province Crop Chemical Control Engineering Technology Research Center.

Fuji apple Demonstration of promoting branch effect scheme

Test time and place: September-October 2021, Technology Center

Apple varieties: FUBRAX

Test Method: Growing point spray

Test Result: 2%6-Benzylaminopurine spraying the growing point at the seedling stage of apple (plant height 50-60cm) can effectively promote the germination of fruit side branches and improve seedling value.

Apple seedlings need to pay attention to the variety, dosage, time and method, the general 6-BA recommended use of 500-667mg/L spraying growth point. Medication time is too late to cause out of the branches too short, stop long, unable to form effective collateral. At the same time, attention should be paid to the follow-up of fatty water.
