grapevine latent buds and prompt buds
Vitis vinifera
Grapevine is one of the most important fruit species with wide distribution all over the world. Unlike other perennial woody plants, there are two kind of buds, latent buds and prompt buds, along shoots of grapevine, which are located adjacently between the leaf axils. They are homologous organs from the developmental biology perspective, but show different phenotypes in terms of dormancy: prompt buds can germinate and then develop into shoots in the same year; while latent buds remain dormant to safely overwinter, until the following year, when the environmental condition is suitable for germination
