Variation in nutrients during the fruit development of Daisy tangerine

Abstract

Seasonal progression in the nutritional concentration of fruit peel, pulp and leaves of Daisy tangerine cultivar were evaluated during fruit development period. Marked variations in nutritional content during specific fruit developmental stages were observed. Overall, leaves were the main sight of nutrient accumulation than fruit parts and their concentration was increased with the advancement in fruit maturity. The general order of abundance of macro and micronutrients in leaves was calcium (Ca)>nitrogen (N)>potassium (K)>magnesium (Mg)>phosphorus (P) and iron (Fe)>manganese (Mn)>zinc (Zn)>copper (Cu) respectively. Overall, P and K were higher in the pulp, while most of the micronutrients registered greater accumulation in the peel. However, in case of N, almost equal distribution was observed in peel and pulp of Daisy fruits. Leaf nutrient showed a strong association with peel, pulp and dry matter accumulation
