错误

Nutrient availability influences UV-B sensitivity of ,t is concluded that the increased accumulation of carbon in nutrient-stressed plants, may lead to a reduction of UV-B induced damage because of increased foliar UV-B absorbance by enhanced accumulation of phenolic compounds and leaf thickening.

Effects of UV-B radiation and additional irrigation on the Mediterranean evergreen sclerophyll , L. ass were observed. None of the other measured parameters (mean leaf area, leaf dry mass, leaf thickness, UV-B absorbing compounds, phenolics, tannins and photochemical efficiency of PSII) were affected by either treatment. Combined UV-B/water effects were not significant. We may conclude that althou
