Studies on Effect of plant growth regulators to improve the colour and sugar content of Grapes” (Vitis vinifera L.).cv. Red Globe was conducted in the field of a progressive grape grower at Kaalampalyam (10 O 58’49.17” N and 76 O 55’ 15. 81”E and elevation of 1352 ft from MSL) near Perur area of Coimbatore district in Tamil Nadu. The experiment was laid out in a randomized Block design with 7 treatments and each treatment was replicated four times. The data recorded on various parameters viz., vegetative growth, flowering, fruit yield, Quality etc., were statistically analysed. Significant differences were observed among the growth regulators on various vegetative growth parameters in Grapes (Vitis vinifera L.). cv. Red Globe. Among all the treatments, number of bunches per vine was significantly higher when sprayed with ethephon 200ppm (T4) compared to other treatments. (6.53 cm), the berry size and berry weight of the grapes were found to be maximum in the bunches treated with CCC 500ppm (T2) (6.57 g), There was no impact on the number of seeds by the treatments. The ethephon 200ppm (T4) treatment exhibited superior quality in terms of juice content, total sugars and colour value.
