Abstract

SummaryTwenty-two of 24 tomato genotypes and five of eight genotypes grown during two seasons had increased total fruit yields when sprayed with 2,4-D at 5 ppm. 2,4-D caused a reduction in leaf area and altered certain flower characters such as stylar length and the percentage of introvert flowers.
