Biological stimulation in germination.

摘要: Introduction: MANY seeds, spores, and pollen grains will only germinate when they are associated with active independent tissues. Moreover, many of the characteristics situation strikingly similar in different groups. Some these similarities have already been emphasized by other writers, others not. It is purpose this article to provide a general review subject based on contention that sufficiently close warrant hypothesis same phenomenon involved throughout several The one some significance two connexions. An examination nature stimulation contributes an elucidation aspect germination process therefore relevant consideration factors dormancy. Secondly, as indicated below, effect undoubtedly due production tissue particular chemical activators which promote development dormant unit. probable not hitherto isolated identified, topic has important implications for growth-promoting substances.
