Inheritance of Seed Dormancy in Weedy Rice
should provide new insight into seed dormancy and resistance to preharvest sprouting. Seed dormancy contributes to the adaptability of plants in nature Rice germplasm (Oryza spp.) varies in degree of seed and is of considerable importance in agriculture. The weedy rice dormancy (Roberts, 1961a; Wu, 1978; Oka, 1988, p. 87– (Oryza sativa L.) strains LD, SS18-2, and TKN12-2 and cultivar ‘N22’ 123;...

متن کاملNatural variation for seed longevity and seed dormancy are negatively correlated in Arabidopsis.
Dormancy is a state of metabolic arrest that facilitates the survival of organisms during environmental conditions incompatible with their regular course of life. Many organisms have deep dormant stages to promote an extended life span (increased longevity). In contrast, plants have seed dormancy and seed longevity described as two traits. Seed dormancy is defined as a temporary failure of a vi...
