Assessment of viability loss in stored seeds
Seeds were collected from the Botanical garden of Kerala Agricultural University, Trichur, and stored in normal room temperature. For checking the loss of viability of seeds on storage at room temperature, experiments on seed germination were conducted at monthly intervals with seeds stored for six months. Seeds were soaked in water for 24 hrs and then sown in pots. The germination percentage was calculated on the fifth day of sowing the seeds.
