Abstract : Seeds of the mango cvs Desi and Dasheri were germinated immediately after harvest or 30 or 45 days later. Seed germination which was 100% in both cvs at 0 and 30 days after harvest declined to 66% at 45 days after harvest. The contents of total N and P, protein N and soluble N, non-reducing and reducing sugars and RNA-P and DNA-P were determined in dry and soaked seeds at 0 and 35 days after harvest. The data are tabulated. In dry seeds, with aging, there were no significant changes except for some decline in RNA-P and reducing sugars. In soaked seeds considerable post-imbibition hydrolysis of non-reducing sugars and DNA-P was noted in freshly harvested seeds and little or none in aged seeds. Post-imbibition degradation of RNA-P was greater in aged seeds.
