Initial characterisation of low and high seed dormancy populations of Lolium
The physiological and biochemical bases of seed dormancy in Lolium rigidum (annual ryegrass) are largely unknown, and study of this process is complicated by the outcrossing nature of the species and the strong influence of environment on seed dormancy.
Dark-mediated dormancy release in stratified Lolium rigidum seeds is asscoiated with higher activites of cell wall modifying enzymes and an apparent increase in gibberellin sensitivity
Dormancy release in freshly matured, imbibed annual ryegrass (Lolium rigidum) seeds is inhibited by light and involves a decrease in seed sensitivity to abscisic acid. Other processes involved in dormancy release in the dark were investigated by measuring seed storage compound mobilisation and the activity of cell wall-degrading enzymes.
