摘要
在室外自然光的基础上，增加0μW／cm^2（CK组）、10．8W／cm^（T1组）、25．6W／cm^（T2组）3种紫外线-B（UV—B，280-320nm）辐射强度，研究UV—B辐射增强对葡萄植株形态的影响。结果表明：（1）对于节间，处理组T1对近生长点的节间有一定的促进作用，但伸长量相对于CK不显著；辐射处理下生成的节间，最终随着辐射量的累积节间长度受到的抑制越显著，且T2〉T1〉CK。（2）与对照相比，处理组的株高和叶面积都有明显的降低，且T2〈T1〈CK。
On the basis of outdoor natural sunlight, three radiation intensities including 0 μW/cm^2 （CK）, 10.8 μW/cm^2（T1） and 25.6 μW/cm^2（T2） of ultraviolet- B radiation （UV- B, 280 to 320 nm） were used to study their effects on the morphology and physiology in plants of grape. The results showed that： （1） The treatment T1 could promote the stem nodes near to the growing point, but the amount of stretching was not obvious compared to that of CK; Under the treatments of radiation, the length of the stem nodes was obviously restrained with the accumulation of radiation, and the sequence was： T2 〉T1 〉CK. （2） Compared with the con- trol, the height and leaf area of the treatments were obviously decreased, and the sequence was： T2 〈 T1 〈 CK.
