Table I. GA concentration (ng g−1 fresh weight) in unpollinated control ovaries, ovaries treated with NPA, and decapitated plants.
Flowers were emasculated on day −2, and application of NPA and plant decapitation were carried out on the day equivalent to anthesis (day 0). Ovaries and fruits were collected at day 10 (control and NPA-treated plants) or day 13 (decapitated plants). Values are means ± se of three biological replicates.
