Abstract

Polyamines are essential compounds for growth and development in plants. An attempt has been made to find out the endogenous polyamine profiles in various parts and during the ontogeny of fruit formation of two commercially important Coffea species viz., arabica and canephora. Putrescine (Put), spermine (Spm) and spermidine (Spd) are the predominant polyamines during the ontogeny of fruit and their level increased with the advancement of fruit development. However, in the initial stages of flower and fruit development Spm levels were found to be decreased. Elevated levels of major polyamines Put, Spd, and Spm were observed in zygotic embryos than in somatic embryos. Along with this cadavarine (Cad) and other biogenic amines viz., tyramine (Tyr) and tryptamine (Try) were also found during the ontogeny of fruit in C. canephora. In this study the enodogenous polyamine profiles in coffee tissues and beans have been addressed.
