In ‘Irwin' mango cultivated in heated greenhouses, to clarify the standard for determining when to start heating, the relationship between the degree of sprouting of the fruiting maternal branch during heating and budding rate after heating was examined. Also, to clarify on how to grow branches that are suited for heated cultivation, the relationship between timing of germination of the fruiting maternal branch and budding. 1. By categorizing the degree of sprouting into 1, 2 and 2, based on morphological characteristics of the apical bud of fruiting maternal branch, the budding rate after heating was examined. As a result, a difference in budding rate was seen, depending on the degree of sprouting, and, in degree 3, the budding rate was 100% on the 10^th day after starting heating. In this degree, the number of days before budding is fewer than that of degree 1 and 2, and the budding rate was higher as well. In degree 1, a difference in budding rate was seen between 2 test fields: 80% and 15%. There was a tendency that the more advanced the degree of sprouting of the branch at the time of starting heating, the fewer the number of days before budding, and the higher the budding rate. 2. As for the relationship between timing of germination of the fruiting maternal branch and budding, the earlier the timing of germination of the branch, the earlier the timing of budding, and the higher the budding rate. New branch germinated before mid-October was found to have a higher budding rate. From these, it was clarified that, the starting heating of mango can be determined by the degree of sprouting of the apical bud of fruiting maternal branch, and the budding rate increases if the heating is started from the point where the scale leaves of the apical bud of fruiting maternal branch open up and the morphologlcal flower bud differentiation is identified. In addition to these, because the earlier the timing of germination of the fruiting maternal branch, the earlier the timing of budding and the higher the budding rate, pruning must be conducted immediately after harvest, and germination of new branch, which becomes the fruiting maternal branch, must be induced.
