Fruit ripening, Plant movement
Fruit Ripening:- > Fruit ripening is a genetically programmed stage of development overlapping with senescence. > The fruit is said to be ripe when it attains its full flavour and aroma and other characteristics of the best fruit of that particular cultivar. > The words “mature “and “ripe” are essentially synonymous when used to describe these fruits that ripe on the plants known as non-climacteric. > However, in case of climacteric fruits a mature fruit require period before attaining a desirable stage of edibility. Table 1. List of climacteric and non-climacteric fruits Changes during Fruit Ripening:- 1. Cell Wall Changes:- - Cell wall consists of pectic substances and cellulose as the main components alongwith sma1amounts of hemicellulose and non-cellulosic polysaccharides. - In cell wall, the changes particularly in the middle lamella which is rich in pectic polysaccharides are degraded and solubilised during ripening. - During this softenin...
