Growth rates of ovaries/fruits and petals in female, bisexual and male flowers of the parthenocarpic cultivar Cavili. (A) Female flower. (B) Bisexual flower with a partial development of stamen. (C) Male flower. (D) Ovary size of female and bisexual flowers with the same time of development. Flowers were tagged when they were 4 mm in length (time 0), and allowed to grow for 20 days in the case of female and bisexual flowers, and 24 days in the case of male flowers. (E) Comparison of ovary/fruit longitudinal growth rates between female and bisexual flowers. (F) Comparison of petal longitudinal growth rates of female, bisexual and male flowers. Note that petal growth is delayed in bisexual flowers, but not as much as in male flowers. Anthesis in the bisexual flowers is delayed even more than in male flowers. Statistical analysis was performed using the LSD method (p ≤ 0.05; n = 15).
