STUDY OF BIOCHEMICAL CHANGES OCCURING AT DIFFERENT STAGES OF SEVERAL CULTIVARS OF MANGO (MANGIFERA INDICA L.)Bhamini V. Parekh, N.l. Patel, A.R. Jalandra, M.M. Ramani and A.D. GadhiyaAbstract The experiment entitled Studies on biochemical changes of some mango (Mangifera indica L.) cultivars. was conducted at ASPEE college of Horticulture and Forestry, Navsari Agriculture University, Navsari. In this experiment eight cultivars of mango viz., Sonpari, Alphonso, Kesar, Dashehari, Rajapuri, Totapuri, Ratna, Amrapalli were considered. The experiment was laid out in completely randomized design (CRD) with eight treatments and three repetitions. With respect to chemical parameters, Alphonso recorded maximum total sugars (%), reducing sugar (%) and non- reducing sugar (%) at all the stages of growth. Kesar noted maximum total soluble solids (TSS %) at marble and mature stages while, Ratna noted maximumbTSS at ripening. Totapuri noted least titrable acidity (%) at pre mature and mature stages while, Amrapalli noted lowest titrable acidity (%) at ripe stage. Fruit firmness (kg/cm2) was noted maximum in Amrapalli at pre mature and ripe stages. TSS: acidity ratio was recorded maximum by Totapuri at pre mature and mature stages while, it was found maximum at ripening stage in Alphonso. Ascorbic acid (mg/100 g pulp) was found maximum in Rajapuri at all the stages of growth.
