INDUCTION OF SEEDLESS LOQUAT |

| Abstract:
Gibberellic acid applied at a concentration of 250 ppm after the emergence of floral buds or NAA applied at 20 ppm during full-bloom produced seedless fruits. Low concentrations of either chemicals reduced the number of seeds by half. Gibberellic acid also increased the length of fruit panicles (up to 50%) and fruit set. Seedless fruits were smaller, elongated and matured 4–5 weeks earlier than seeded fruits. The reduced size may have been related to early maturity as much of the weight increase of loquat fruits normally occur just prior to maturation. Therefore, seedless loquats need a further treatment(s) to increase fruit size. | |
