In this article:

Potted vines of Vitis Vinifer L., cv. ‘Cabernet Sauvignon’, ‘Shiraz ‘, ‘Rhine Riesling ‘ (‘White Riesling’),and ‘Clare’e Riesling ‘, were maintained in growth from 4 days after bud burst to berry set. Light intensity was not varied.

Temperatures (oC day/oC night) were 14/9, 20/15, 26/21, 32/27, and 38/33.

The number of days from transfer to cabinets until flowering decreased from 70 at 14/9 to 24 at 26/21 to 20 at 38/33.

It is a matter for conjecture whether these results, obtained with small manipulated plants, would also be obtained with large field plants.
