The lamps of light emmitting diode of 660nm (LED660) and 450nm (LED450) and a lamp comdined LED660 and LED450 were manufactured by way of trial experiment Long-day Treatment by LED660 and LED660+450 stimuIated the shoot growth and differentiaton of flower primcrdium inPione' grapes Long-day treatments were conducted in three grape cuItivars by lamps of siIica, red and plant-lux under three different conditions day-Iength Judging from the superior shoot growth and bunch differentiation, Iong-day treatment was the most effective in Pione', foIIowed in Ddaware', and 'Muscat of Aiexandria' The shorter the natural daylength, the larger was the effectiveness of long-day treatment irrespective of lamps used. To evaIuate an additional Iighting under growing conditons, commerciaI Pione' grapes were kept to long-day by a Piant-Iux. Long-day treatment was effective in vine growth and berry production, especiaIIy in a twice- a-year harvesting system.Effect of UV-A illumination on anthocyanin accumulation in skin of grapebemes varied wideIy among tha cuItivars. When berry dusters of Gros Colman' grape grown in a commerciaI gIass house were iIIuminated by UV-A for ii weeks from Veraison to harvest UV-A enhanced accumuIation of anthocyanin in the skin White hight was 'aIso promotive, but the Effectiveness was consideradIy Iess than UV-A PAL(L-phenyIaIanine ammonia-Iyase) activity in the skin markedIy rose Just after UV-A iII umination. Anthocyanin constituents in the skin were changed by UV-A iII umination , aIthough depending on the grape cultivars. Based on the genetic analysis, it Was thought that the genes of myb 11, PAL 5and PAL 14 may reguIate the synthesis of anthocyanin in berry skin

通过试验制作了660 nm发光二极管(LED660)和450 nm发光二极管(LED450)灯以及LED660和LED450组合灯。用LED660和LED660+450进行长日照处理对葡萄品种迎春花的生长和分化有抑制作用。在3种不同条件下进行葡萄品种的长日照处理，从枝条生长和丛生分化的优势来看，长日照处理效果最好，其次是DIDA和Aiexandria。为了在生长条件下评估额外的光照，商业上的Pione葡萄被Piant-Iux保存了很长一天。长日照处理对葡萄生长和果实产量有明显的促进作用，尤其是在一年两次采收的条件下，UV-A光照对葡萄果皮花青素积累的影响因品种而异。用Veraison公司的UV-A照射玻璃温室栽培的格罗斯·科尔曼葡萄果实2周，收获果皮时，UV-A促进果皮花青素的积累也有促进作用，但效果不如UV-A PAL(L苯丙氨酸氨酶)活性在UV-A III作用后果皮中的花青素含量显著升高。根据遗传分析，MYB 11、5PAL和PAL 14基因可能调节浆果果皮花青素的合成。
