Greengram, Heavy rainfall, Maize, Vivipary


In angiosperms, if high rainfall coincides during the seed development period, hormonal imbalance occurs in seeds (ABA and GA), this hormonal imbalance leads to escape the dormancy, and thereby, seeds germinate on the plant itself. This unusual kind of germination is known as vivipary and based on strength of the developed embryo to break through the seed coat, two kinds of vivipary have been categorized, viz. True vivipary and Cryptovivipary. Certainly, this kind of germination will make a way for loss in seed quality. Nevertheless, vivipary is the reproductive strategy adopted by mangroves and this advantageous character can be helpful in the greening of barren lands.
