Flowering: Difference between revisions
Created page with "'''Flowering''' is a key phenological stage in the annual growth cycle of the grapevine, during which the vine’s flowers open and fertilisation occurs. It marks the transition from vegetative growth to reproductive development and plays a decisive role in determining yield and potential fruit composition in the resulting wine.<ref>Robinson (ed.), ''The Oxford Companion to Wine'', Oxford University Press, 2015, ISBN 9780198705383.</ref> == Tim..." |

Flowering typically occurs several weeks after [[budbreak]], once sufficient heat accumulation has been reached. The exact timing varies according to [[climate]], site conditions and [[grape variety]]. Most cultivated grapevines (''Vitis vinifera'') have hermaphroditic flowers and are largely self-pollinating.<ref>Mullins, Bouquet & Williams, ''Biology of the Grapevine'', Cambridge University Press, 1992, ISBN 9780521305071.</ref> | [[Flowering]] typically occurs several weeks after [[budbreak]], once sufficient heat accumulation has been reached.

The process begins when the protective caps (calyptrae) detach from the flowers, exposing the reproductive organs. Successful pollination and fertilisation lead directly to [[fruit set]].<ref>Keller, ''The Science of Grapevines'', Academic Press, 2015, ISBN 9780124199873.</ref> | The process begins when the protective caps (calyptrae) detach from the flowers, exposing the reproductive organs.
