【摘要】 笔者为调节冬季温室栽培郁金香的花期,采用白光、UVB、UVA、蓝光和红光等光质对郁金香进行补光处理,探讨不同光质对郁金香生长和开花的影响。结果表明:不同光质补光对郁金香花朵形态无明显影响,但除白光外,其他补光处理均提早开花并提高开花整齐度,红光和蓝光明显促进郁金香植株干物质向花朵分配的比例。更多还原

【Abstract】 In order to regulate the flowering period of tulip growing in greenhouse during winter,effect of supplemental lighting with white,red,blue and ultraviolet(UVA and UVB) light on the growth and bloom of tulip were studied in a solar greenhouse.The results showed that,compared with control (i.e.no supplemental lighting treatment),there was little difference observed in flower quality.All the supplemental lighting treatments except white light advanced the bloom and reduced the difference in bloom time of tulip.Red and blue light increased the percents of dry matter partitioned to flower.更多还原
