| 英文摘要 | Tartary buckwheat (fagopyrum tataricum gaertn.) crops were grown in sheltered field plots for two consecutive seasons under reduced, near-ambient and two supplemental levels of ultraviolet-b radiation (uv-b, 280-315 nm). the effects of different uv-b treatments on crop growth, development, yield and leaf pigment levels were determined. all four treatments were replicated three times in a randomized complete block design. near-ambient solar uv-b (approximately 84-88% of solar uv-b) was provided by using a teflon film, attenuated solar uv-b radiation (43-49% reduction in solar uv-b) by using a cellulose acetate film, and supplemental uv-b radiation by the use of uv fluorescent lamps (two levels: 5.30 and 8.50 kj m(-2) day(-1)). the prevailing ambient solar radiation caused a negative effect on plant growth and yield. the crop growth, total biomass, final seed yield, thousand-grain weight and the amount of photosynthetic pigments decreased under near-ambient and enhanced uv-b radiation, while crop development was promoted by enhanced uv-b radiation. leaf rutin concentration and the amount of uv-b absorbing compounds were increased by uv-b with the exception of the 8.50 kj m(-2) day(-1) supplemental levels. our results showed that tartary buckwheat is a potentially uv-b sensitive species, and the crop response to uv-b radiation is associated with uv-b intensity, environmental factors and growing season.
