摘要:
在大田试验条件下，研究UV-B辐射增强对棉花生长发育的影响。通过人工增加对棉花UV-B辐射，设置4个处理，每个处理的辐射剂量分别为0 W/m2 (R0)、0.5 W/m2 (R1)、1.0 W/m2 (R2) 和1.5 W/m2 (R3)，研究了UV-B辐射增强对棉花株高、茎粗、叶面积、叶片表观伤害、产量和品质的影响。结果表明：随着UV-B辐射增强，R1、R2和R3处理组的株高、茎粗、叶面积分别与对照达到了极显著水平(P The objectives of this research were to study the influences of enhanced ultraviolet radiation (UV-B, 280 - 320 nm) on physiological indicator, yield and quality of cotton. We set four treatments of 0 w/m2 (R0), 0.5w/m2 (R1), 1w/m2 (R2), 1.5 w/m2 (R3) by increasing artificial UV-B radiation and studied the effect of enhanced Ultraviolet-B radiation on plant height, stem diameter, leaf area index (LAI), apparent injure in leaf, yield and quality of cotton. The results showed that the plant height, stem diameter and LAI had significant correlation with the increasing Ultraviolet- B radiation (P
