| 摘 要： | 在云南玉溪主产烟区的通海县(海拔1806.0m)自然环境中,通过覆膜减弱UV-B的辐射强度(分别是自然环境下的25%、50%和65%),采用盆栽试验研究了UV-B辐射对烤烟K326团棵中后期-现蕾期部分形态特征的影响。结果表明:减弱自然环境下的UV-B辐射对K326株高、最大叶长、叶宽及叶面积、茎围、节间距和叶数等没有显著影响。但在不同减弱UV-B处理下,株高、最大叶长、最大叶面积和节间距等呈现增加的趋势,而叶数则有减少的趋势。说明目前通海的UV-B辐射水平已对K326的形态建成产生了一定的抑制效应。 |

| Abstract: | To study the effects of Ultraviolet-B(UV-B)radiation on morphological characteristics of tobacco cultivar K326,the potted experiment,which reduced 25%,50% and 65% solar UV-B intensities during tobacco vegetative stage(16th-28th June),was conducted in Tonghai County(1806.0m) Yunnan province,one of the main tobacco production bases in China.The results showed that there were no significant effects of attenuated UV-B radiation on plant height,maximum leaf length,leaf width and leaf area,stem circumference,join... |
