Description Study on seed development, the onset of germination, physiological maturity in cucumber (Cucumis sativus L) were undertaken to identify the suitable stage for seed extraction from the fleshy fruit. The manually pollinated fruits were harvested at periodic intervals, from 0-40 days, and the extracted seeds were tested for germination, dry matter accumulation, moisture content. The onset of germination at 12 DAP is far earlier than the physiological maturity. The decrease in germination during maturation drying was observed along with increased seed quality in seedling dry weight and seed vigour index. During various stages, the GA3 and ABA quantification during different seed developmental stages showed the relation between germination and the balance of these hormones. The germination initiated and increased with the increase in GA3: ABA ratio. The high ABA content before the onset of seed germination enabled the seed to become dormant. Its slight increase during maturation drying for attaining stress tolerance during the loss of water was observed. In the present study, we noticed no relation between hormonal balance and seed vigour during developmental stages. The high vigour and germination above the Indian minimum seed certification standards at maturation drying made it a suitable seed extraction stage.
