AB Potted vines of Vitis vinifera L., cv. 'Cabernet Sauvignon', 'Shiraz', 'Rhine Riesling' ('White Riesling'), and 'Clare Riesling', were maintained in growth from 4 days after bud burst to berry set. Light intensity (2500 ft-c and day length (16 hours) were not varied. Temperatures (°C day/°C 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. Variation in the temperature range used to attain a mean daily temperature of approximately 18.3°C (as given by 20/15) had no effect on time to bloom. It is a matter for conjecture whether these results, obtained with small manipulated plants, would also be obtained with large field plants.
