Mango is a favourite fruit of almost everyone on the earth. It is full of vitamins and minerals and is of great taste. It is also the national fruit of India. It has gained worldwide popularity starting from ancient times. One of the major reason for low productivity of Alphonso in Konkan region is low rate of physiological process during monsoon season, due to low diffused sun light intensity. The present investigation entitled “Effect of Polyamines (Spermine, Spermidine and Putrescine) and Triacontanol on physiological behaviour of mango cv. Alphonso under rainy season of Konkan area” was conducted and laid out in randomized block design with thirteen treatments. Treatment details: T1 (Triacontanol 10 ppm), T2 (Triacontanol 15 ppm), T3 (Triacontanol 20 ppm), T4 (Spermine 150 ppm), T5 (Spermine 450 ppm), T6 (Spermine 700 ppm), T7 (Spermidine 200 ppm), T8 (Spermidine 600 ppm), T9 (Spermidine 1000 ppm), T10 (Putrescine 100 ppm), T11 (Putrescine 250 ppm), T12 (Putrescine 450 ppm) and T13 (control). Thus, from present investigation it could be concluded that rate of photosynthesis increased by foliar application of Putrescine shown better effect under diffused sun light intensity conditions.
