荞麦(Fagopyrum spp.)是一种营养丰富的重要杂粮,也是具有开发潜力的优质饲草资源,病害的发生使荞麦的品质与产量下降,是影响荞麦生产的主要限制因子之一。目前引起荞麦真菌病害有14种,病原物有16个属,另有其他病害8种,包括细菌、病毒和线虫病。本文通过对国内外荞麦病害研究的文献归纳总结,国内外对其轮纹病、霜霉病和根腐病、立枯病等叶部、根部病害的危害程度、发生规律和防治等方面得到不同程度的研究,但对其他叶部病害和种带真菌研究较少,今后应更多关注影响荞麦生长的主要病害种类,进行病原菌多样性,加强病害发生规律研究,制定出切实可行的防治措施。

以带内生真菌(E+)和不带内生真菌(E-)的多年生黑麦草(Lolium perenne)种子为材料,采用室内种子萌发实验,分析多年生黑麦草在不同pH(4.47~6.12)砖红壤浸提液中种子萌发、幼苗形态指标及生理指标的变化,探讨内生真菌对酸性环境中多年生黑麦草幼苗生长和生理特性的影响。结果表明:(1)在相同带菌情况下(内生真菌侵染E+或未浸染E-),随着砖红壤浸提液pH值的降低(浸提液酸性的增强),E+和E-种子发芽率、发芽势、发芽指数、活力指数、胚芽长、胚根长、胚芽鲜重和胚芽干重均表现为逐渐下降的趋势,且5个砖红壤浸提液处理均显著低于相应对照(CK,pH 6.12);幼苗脯氨酸含量、超氧化物歧化酶活性、过氧化物酶活性和丙二醛含量呈上升趋势,且5个砖红壤浸提液处理均显著高于相应CK。(2)除CK外,在相同pH砖红壤浸提液处理下,内生真菌侵染显著提高了多年黑麦草的发芽率、胚芽长、鲜重和干重等形态指标及脯氨酸含量和超氧化物歧化酶活性,却显著降低了过氧化物酶活性和丙二醛含量;在砖红壤浸提液pH为4.47~6.12时,E+萌发种子胚根长与E-之间无显著差异。研究发现,不同pH砖红壤浸提液对E+和E-种子萌发、生长和生理有一定的影响,内生真菌的侵染可促进宿主植物的生长,同时对砖红壤浸提液pH值具有较宽的适应范围,可将多年生黑麦草内生真菌共生体应用于酸性土壤改良。
