Chlorophylls and Carotenoids in Sweetpotato Genotypes

Sweetpotato is a starchy root crop. Its tops and storage roots are being consumed by human in various forms whereas its vines are excellent feed of livestock. Leaf chlorophylls and carotenoids which takes part in photosynthesis have significant influence on the growth yield and nutrients content in both leaves and storage roots of sweetpotato genotypes. This book explains the morphophysiological characteristics especially chlorophylls and carotenoids status dry matter partitioning storage root bulking rate crop growth rate relative growth rate and net assimilation rate; yield contributing characteristics viz. storage root number length and diameter fresh and dry weight of storage roots and nutritional parameters viz. protein carbohydrate fat total ash crude fibre starch total sugar total soluble solids calorific value phenolic compounds vitamin C beta-carotene tannins iron zinc calcium magnesium potassium and phosphorus of leaves and storage roots of nine local and exotic sweetpotato genotypes. It also explains the correlation of leaf chlorophylls and carotenoids with growth yield and nutritional parameters of sweetpotato genotypes.
