What Stimulates Seed Germination?
What Stimulates Seed Germination? Bioactive gibberellins (GAs) promote seed germination in a number of plant species. In dicots, such as tomato and Arabidopsis, de novo GA biosynthesis after seed imbibition is essential for germination. Light is a crucial environmental cue determining seed germination in some species. What are the 4 factors that triggers seed germination?
