Seeds of neem (Azadirachtaindica) and jamun (Syzygium cuminii) were subjected to accelerated ageing conditionsof high temperature (41 ± 0.5 °C) and relative humidity (100%) to assess theirstorability. Seed samples drawn at 24-h intervals were tested for germination andseedling vigour in terms of root and shoot lengths, vigour index and dry weight.The reduction in germination below 50% occurred earlier in jamun (4th day ofageing) than in neem (6th day). However, seedling vigour deteriorated much quickerin neem than in jamun. Therefore, it is concluded that seeds of both these speciesshould be sown in the nursery immediately after collectio
