摘　　要：以不同葡萄品种(‘凤凰51’、‘黑比诺’、‘贝达’和‘巨峰’)试管苗为材料,研究其在红、黄、绿、蓝和白5种光质条件下的生长发育。结果表明:白光有利于试管苗的增殖、生物量积累及叶绿素的合成,且净光合速率最强;红、黄光促进试管苗根和茎的伸长生长;蓝光有利于白藜芦醇的积累,而叶绿素a/b的比值最小。Test-tube plantlets of different grape varieties （Fenghuang 51, Pinot Noir, Beta and Kyoho） were used in the experiment to study their growth and development under 5 different light qualities （red, yellow, green, blue and white light）. The results showed that the white light was the best for the proliferation, biomass, chlorophyll synthesis and net photosynthetic rate of grape test-tube plantlets. The shoot and root elongation growth were promoted under red or yellow light. Under blue light resveratrol production was highest, but the chlorophyll a/b ratio was the lowest.
