Effects of Trylone and Tomatotone on fruiting of 'Miguel Pereira' tomato plants

Abstract

This work was carried out to determine the effect of plant growth regulators on the fruiting of tomato plant, Lycopersicon esculentum cv. Miguel Pereira. In this trial Trylone (2-hidroximetil 4-chlorophenoxyaceticacid) at 10 ml/l and 20 ml/l, and Tomatotone (p-chlorophenoxyacetic acid) at 10 ml/l and 20 ml/l were sprayed during anthesis of the first two flowers of the first three clusters. It was verified that Tomatotone 10 ml/l and 20 ml/l increased the number, length and weight of tomato fruits; Tomatotone 20 ml/l induced the formation of fruits with a better classification. Tomatotone and Trylone reduced the number of aborted flowers. Trylone 20 ml/l increase the percentage of parthenocarpic fruits.
