This stage of the grapevine 's annual vegetation cycle begins six to eight weeks after budding. The timing depends on the year-specific temperature development, the temperatures reached at the respective location and the typical growth of the variety under changing weather conditions. Constantly warm temperatures with a good water supply accelerate shoot growth and thus the formation of the inflorescence (lat. inflorescence, also known as the flower, umbel, dome or spike) on the third to seventh shoot node.
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
