Recently, cultivars reproduced by vegetative propagation are increasingly used to produce tomatoes with lateral shoots used for reproduction. To promote the development and uniformity of lateral shoots, treatments by decapitation and training on some tomato cultivars were investigated. The formation of lateral shoots after decapitation was fastest in the cherry tomato group, then in the common beef tomato group but slowest in the First beef tomato group. Treatment by decapitation enhanced the uniformity of lateral shoots among the various leaf positions, but the effect was insufficient. Horizontal training initially increased the number of lateral shoots after treatment, but finally the number became similar to that seen in vertical training. The number of harvested lateral shoots eventually depended on the number of leaf axils on the mother plant. The multiplication rate was about 65 times that of the mother plant by counting the lateral shoots generated from the main and the second stems.
