Effects of benzoic acid on pine wilt disease caused by bursaphelenchus xylophilus
在室内条件下,初步研究苯甲酸对松树和松材线虫病的作用。用不同浓度的苯甲酸溶液分别处理松枝,显示低浓度苯甲酸溶液能显著延长松枝的存活期,高浓度苯甲酸溶液处理的松枝针叶出现褐变现象,但对松枝的存活期没有影响,其症状与松材线虫病不同。分别用1.0mmol.L-1的苯甲酸溶液和自来水培养接种松材线虫的松枝,在用苯甲酸溶液处理的接种松枝中,虽然松材线虫仍能大量增殖,但与用自来水培养的接种松枝相比,其蒸腾强度显著增强,失水萎蔫程度显著降低,存活期显著延长,这说明苯甲酸在松材线虫病树中可能起着抑制与病害相关的致病菌或提高松树抗病能力的作用。...
