Unpollinated WT AN stages. The concentration of GA 1 , suggested previously to be the active GA in tomate, was 2 -4 times higher. Un-ovaries degenerated but GA 3 application induced parthenocarpic fruit growth. On the contrary, parthenocarpic growth pollinated pat-3/pat-4 ovaries at FB, PR and AN stages also contained relatively high amounts (5 -12 ng g − 1 ) of of pat-3/pat-4 fruits, which occurs in the absence of polli-GA 3 , a GA found at less than 0.5 ng g − 1 in WT ovaries. nation and hormone treatment, was not affected by applied GA 3
