WebThe first step in the seed germination is imbibition i.e. absorption of water by the dry seed. Imbibition results in swelling of the seed as the cellular constituents get rehydrated. The swelling takes place with a great force. It ruptures the seed coats and enables the radicle to come out in the form of primary root. ADVERTISEMENTS: WebSwelling of de-hulled seeds was reduced initially, since the seed coat swells faster than the cotyledons in the initial stages of water uptake. Addition of carbonate salt to the soaking solution generally reduced water absorption and swelling. the hard-to-cook defect was manifested by reductions in the rates of water uptake and diminished ... WebThe uptake of water by seeds is called imbibition, which leads to the swelling and the breaking of the seed coat.
