• To study the effects of supplemental lighting with ultraviolet (UV), blue and red-blue lights on quality development of grape berries under protected cultivation to promote early maturing, four-year-old vines of 'Ruidu Xiangyu' grape using 'Beta' as rootstock were used in this experiment. The results indicated that blue and ultraviolet lights were poor in greenhouse environment. Compared with the control, blue and ultraviolet lights lasting 6 hours at night significantly accele-rated the increase of berry mass, fruit diameter, sugar content and the decrease of acidity content during the grape development, but the effect of red-blue light was not obvious. At the fruit maturation, berries supplemented with the three types of light were heavier, and those treated with the UV light were the heaviest. Additionally, grape berries supplemented with blue light had the highest glucose, fructose and total sugar contents, while the sugar contents in berries supplemented with UV light was lower than that under blue light
