Maturação fisiológica de sementes de berinjela

Abstract

Potential herbal, its relationship with healthy diet and weight loss are current information that led to the growing demand for eggplant production, resulting in the search for the improving the techniques to the culture production, involving the use of technologies for production seed quality. Thus the objective of this study was to define the period of physiological maturity of eggplants’seeds and the ideal harvest point for eggplant’s fruits, based on the physiological quality of seeds extractes from these fruits. For fruit production, the experiment was conducted in beds inside the greenhouse where flowers were labeled according to anthesis to harvest the fruit at 40, 47, 54, 61, 68, 75 and 82 days after anthesis. After extraction the seeds were divided into two groups: fresh and dried to 8% moisture. To analyze the physiological quality of seeds, tests and determinations were performed with: humidity, dry matter, 1000 seed weight, electrical conductivity, germination, germination speed index, protrusion of the radicle, protrusion of the radicle speed index, emergence and emergence speed index. For the eggplant cultivar Embu, physiological maturity of seeds is in the range 68 to 82 days after anthesis and the point of maximum physiological quality, best harvest point within the study period, was at 82 days after anthesis where they have the best germination and vigor, considering specially the ability to produce normal seedlings. The conclusion is valid for both, fresh seeds and dry seeds.
