Abstract : The levels of common free polyamines in the pericarp and seeds of developing fruits of mango cv. Alphonso, grown in an orchard at Hessaraghatta, Bangalore, Karnataka, India, were analysed to examine their relationship with fruit growth and development. Putrescine and spermine were the major polyamines in the fruit pericarp and seed, respectively. The levels of total polyamines and individual polyamines, putrescine and spermine increased in the pericarp and were highest at 45 and 30 days during the years 2000 and 2001, respectively. In seeds, the total polyamines, spermine and spermidine levels were high at 90 and 75 days after fruit set during the same years. The high polyamine concentration in fruits preceded its active growth phase, while the high polyamine concentration in seeds coincided with the active growth phase.
