摘要: 以云烟87为材料,在苗期人工增补不同时间和强度UV-B后,检测烟苗生理指标、生长情况和烤后烟叶经济性状指标。结果表明,短时间UV-B照射(1.20 W/m2、每天1 h)显著提升了烟苗的根系活力,显著提高了其SOD、POD和PPO酶活性; 持续均匀低强度UV-B照射(1.20 W/m2、每日照射1 h,累计10 h)对烟苗形态、烤后烟叶产质量更有利。因此,增补适量UV-B有利于烤烟设施育苗。

Abstract: Taking Yunyan 87 as material, the physiological indexes, growth condition and economic indexes of flue-cured tobacco leaves were detected after artificially adding different time and intensity UV-B at seedling stage. The results showed that short-term UV-B irradiation (1.20 W/m2, 1 h per day) significantly increased the root activity of tobacco seedlings, and significantly increased the SOD, POD and PPO activities. It was beneficial to the tobacco seedlings and the yield and quality of cured tobacco of UV-B irradiation at continuous and uniform and low-intensity level(1.20 W/m2、1 hour per day,10 hours in total). Therefor, it is beneficial to supplement appropriate amount of UV-B in flue-cured tobacco facilities for seedling raising.

Key words: flue-cured tobacco, UV-B, root activity, enzyme activity, economic traits
