| 摘 要： | 运用植物生活史型的理论与方法,研究了UV-B辐射增强对南方红豆杉Taxus chinensis var. mairei表型性状和紫杉烷类次生代谢产物的影响。结果表明,随UV-B辐射强度增加,南方红豆杉无性生殖表型性状(C)明显增强(z值由0.18增加到0.52),营养生长表型性状(V)相应降低(x值由0.82降低至0.48);3.25 μW · cm-2 · nm-1UV-B辐射处理较对照组和9.76 μW · cm-2 · nm-1 UV-B辐射处理组生物量增量更高;增补UV-B辐射处理显著促进了南方红豆杉叶片中紫杉醇(Taxol)的积累,但对10-去乙酰基巴卡亭Ⅲ(10-deacetylbaccatin Ⅲ,10-DAB)、7-木糖-10-去乙酰基紫杉醇(7-xylosyl-10-deacetyltaxol,7-xyl-10-DAT)有一定的抑制效应,其中3.25 μW · cm-2 · nm-1UV-B辐射处理对紫杉醇诱导效果最为明显。结果表明,在南方红豆杉田间栽培中应注意上层树种搭配、修剪,从而形成适当的UV-B辐射胁迫以诱导紫杉醇含量及生物量增量,达到高产、优质的生态培植目标。
