jasmonate to seed dormancy release and germination is still unclear. Recent studies have shown that seed indole acetic acid (IAA) level increases with imbibition of non-dormant seeds [34,37], suggesting its importance in regulating seed germination, and dormant seeds contain over twofold less IAA than non-dormant seeds . However, exogenous auxin increases seed ABA sensitivity and thereby... When you have a dormant embryo, a storage tissue, and a seed coat, then you have a seed. In some seeds, the endosperm is (retained as the storage tissue).

Germination is also controlled by endogenous factors such as the plant hormones abscisic acid (ABA) and gibberellins (GA) that play a major role in regulating early seed germination through the process of dormancy, which is a block to the completion of germination of a mature intact viable seed (Finch-Savage and Leubner-Metzger, 2006). matter and interactions 3rd edition pdf Germination is also controlled by endogenous factors such as the plant hormones abscisic acid (ABA) and gibberellins (GA) that play a major role in regulating early seed germination through the process of dormancy, which is a block to the completion of germination of a mature intact viable seed (Finch-Savage and Leubner-Metzger, 2006).
