Early pruning was done in an attempt to hasten maturity of fruits in nine varieties of grape vines. It had an adverse effect on the vegetative growth and bearing of vines. The time of maturity of the fruits was not affected.
Post Script:
Tho authors understand that in South India grape vines are pruned in different periods to facilitate the coincidence of the optimum season with fruit development and that trials to induce earliness in vines by pruning at different intervals are under way at the Aurangabad Fruit Research Station, but published information is not available to this effect.
Hayes (2) has referred to the difference in vine growing condition of northern and southern India as ‘In much of northern India, the winters are too cool to allow the grapes to ripen before the rainy season, as is done in Bombay, and the summers are too wet to allow them to ripen at the time they do in Baluchistan’.
