内容記述(抄録等)
We investigated that effects of pinching treatments at seedling stage on the flowering and productivity about the differences between two lateral shoots and untreated control (one main stem) groups in cherry tomato cultivation. As a result, it was shown that the use of two lateral shoots of cherry tomatoes cv. 'Aiko' and 'FS-45' with pinching treatments at seedling stage suppressed fruit enlargement, reduced the incidence of fruit cracking, and increased the yield of marketable fruits. In both cultivars, the quality of the fruit treated with pinching treatments was equal to or higher than those without pinching one. Therefore, although the flowering days of each flower trusses were delayed and the total fruit yields were decreased by the pinching treatments, the unmarketable fruit rates were decreased and the fruit quality was increased, which indicates that the productivity may be improved.
