摘要
该文介绍了一种利用黑松枝条进行化合物对松材线虫作用的生测方法。通过研究枝条的接种线虫数量、含水量以及灭菌处理后对松材线虫繁殖的影响,确定了合适的生测条件,并对几种生测方法的优缺点进行了讨论。
A bioassay with branches of Japanese black pine (Pinus thunbergii Parl) to screen nematicides against pine wood nematodes (Bursaphelenchus xylophilus) was introduced in the paper. The effects of inoculating number of the nematodes, water content in the segments of the pine and sterilization of the segments on the reproduction of the nematodes were studied. Based on the results of the studies the conditions of the bioassay were set up. The advantages and disadvantages of several bioassay methods were also discussed.
