Germination of pearl millet (pennisetum glaucum seeds stored under different condition for six years uri icon

abstract

  • Seeds of 7 pearl millet genotypes (4 land races, 1 commercial hybrid, 1 improved cultivar and 1 weedy type) were stored for 0-6 years at (a) 15-40 deg and 20-90% RH (ambient conditions), (b) 18-20% and 30-40% RH or (c) 4 deg and 20% RH. Seeds were stored in glass bottles, plastic bottles, polyethylene bags, aluminium foil packets, paper packets or cloth bags. In (a), germination was completely lost after 5 years in all containers. In (b), germination after 6 years and averaged over cultivars ranged from an average 23% in paper packets to 51% in plastic bottles. After 6 years in (c) germination ranged from 75% in aluminium foil packets, paper packets or cloth bags to 84% in glass bottles. Significant genotype differences were observed with larger and denser seeds surviving longest., 13 ref., Seeds of 7 pearl millet genotypes (4 land races, 1 commercial hybrid, 1 improved cultivar and 1 weedy type) were stored for 0-6 years at (a) 15-40 deg and 20-90% RH (ambient conditions), (b) 18-20% and 30-40% RH or (c) 4 deg and 20% RH.
