On the 4-year-old Bo Ha orange variety grown at Nong Lam University, Thai Nguyen University, the results of climatological studies showed that there were 4 seasons of seasonal buds forming 4 main branches, consecutively growing. related to fruit yield are spring, summer, autumn and winter crops. In which, two types of branches have an important influence in the fruit-bearing period: the spring season to form fruit branches (flower and fruit-bearing branches) and the autumn crop, which functions as a source of mother branches of the following year's fruit branches. In the years when the tree produces a lot of fruit (the year is good), the spring crop has a very high percentage, while the rate of the autumn crop is very low. In contrast, in the years when the trees had few fruits (years of crop failure), the rate of spring branches was very low, but the rate of autumn branches was very high. The ratio of autumn branches and fruit yield in the following year of Bo Ha orange variety has a close positive linear relationship (r=0.81). The research results are an important scientific basis for developing technical solutions to regulate the appropriate proportion of spring and autumn branches, ensuring high and stable yields.
