Abstract

Diffusible auxin is not present in tomato flowers at anthesis, but significant amounts can be obtained after the plants are treated with gibberellin. The early growth of the ovary in plants treated with gibberellin corresponds closely with growth after pollination and fertilization; the amounts of diffusible auxin are not significantly different over a period of 22 days.
