EFFECTS OF FRUIT AGE, DRYING METHOD AND CONDITION ON SEED QUALITY OF OKRA (Abelmoschus esculentus (L.) Moench) CV. SANTA CRUZ-47
JOSÉ WALMAR SETUBAL, ANTONIO CELSO WAGNER ZANIN E JOÃO NAKAGAWA
Fruits of okra cv. Santa Cruz-47 were harvested at three times: 35, 45 and 55 days after anthesis. Half part ofthe fruits ofeach harvesting time was shelled and the seeds were dried in natural environment oflaboratory or in dry chamber. The other half part of the fruits was dried unshelled in the same two conditions. Water contents of seeds were evaluate at harvesting time and before the germination test, that was carried out when the seeds were in hygroscopic equilibrium with the two environments, The physiological quality of seeds was affected by the interaction effects of fruit age, drying method and drying condition. The highest values of germination were obtained in seeds from fruits with 45 days, when these were dried in natural environment inside or outside of the fruit. The hard seeds percentage increased when the seeds were dried in dry chamber, mainly those inside the fruits. The seeds from fruits with 35 days had the germination percent increased when were dried inside the fruit, in natural environment, and they got similar germination values of the two other harvesting times.
