Seed Germination and and Dormancy are Regulated by Light, Temperature and Plant Hormones
Tobacco seed germination and class I ß-1,3-glucanase (ßGlu I) induction regulated by plant hormonesABA-sensitive ßGlu expression in the endosperm prior to endosperm rupture is widespread among Solaneceous seeds
