Abstract

Common pathogenicity tests on 16-month-old ash plants were performed using isolates of Hymenoscyphus fraxineus and three different Phytophthora spp. isolated under declining ash trees in Wolica Nature reserve in Poland. There were no statistically significant differences among the different inoculation treatments and lesion lengths averaged 1.67 cm. After analyses of inoculated roots, five out of 10 root parameters showed statistically significant differences, and after a Duncan’s Multiple Range test, significant differences were found with control plants while there were no differences among the treatments. The largest root loss was with the treatment inoculated with both H. fraxineus and P. plurivora (HF + PP), and both fine and total root lengths were 2.30 and 2.27 times smaller, respectively, than the non-inoculated control. The earliest mortality of young ash plants was observed also with the HF + PP treatment. Results showed high aggressiveness of H. fraxineus to young ash plants, with indications t...

细花膜壳虫和疫霉菌在细花幼苗上的相互作用

利用波兰沃利卡自然保护区衰退的白蜡树下分离的膜炎球菌和三种不同的疫霉菌对16个月大的白蜡植物进行了常见致病性测试。不同接种处理之间没有统计学上的显著差异，病变长度平均为1.67cm。在对接种的根进行分析后，10个根参数中有5个显示出统计学上的明显差异，在Duncan’s Multiple Range检验后，对照植物发现了显着差异，而处理之间没有差异。最大的根损失是用H.fraxineus和P.plurivora（HF+PP）接种的处理，细根和总根长度分别比未接种的对照小2.30倍和2.27倍。用HF+PP处理也观察到幼龄白蜡植物最早死亡。结果表明，黄曲霉对灰苗具有很高的攻击性，表明黄曲霉对白蜡树幼株具有较强的攻击性。。。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
