Abstract

Silver birch, (Betula pendula), is an important forest tree species in Poland used for afforestation in rural areas and planted in wet forest types to ameliorate excess water. Physiological stress may increase susceptibility of trees to disease and it is hypothesized that insect defoliation can predispose birch to Phytophthora plurivora infection. In order to evaluate the effect of defoliation stress and phytophthora infection, removal of all (100%) or partial (50%) foliage from one-year-old B. pendula seedlings simulating insect damage was carried out in the greenhouse. Inoculation with P. plurivora mycelium at the base of the stem was performed by cutting the bark tissue 5–7 cm above the soil. Stem damage was assessed after 70 days in 2016 and after 365 days (at the end of the next growing season in September 2017) by measuring lesions sizes. We found that B. pendula can serve as a host of the soil-borne pathogen P. plurivora which causes mortality of birch seedlings in Polish nurseries. The results als...

桦木幼苗落叶与多菌疫霉茎侵染的相互作用评价

白桦树（Betula pendula）是波兰一种重要的森林树种，用于农村地区的植树造林，并种植在潮湿的森林中以改善多余的水分。生理压力可能会增加树木对疾病的易感性，据推测，昆虫落叶会使桦树容易感染多菌疫霉菌。为了评估落叶胁迫和疫霉菌感染的影响，在温室中模拟昆虫损伤，从一年生的下垂B.pendula幼苗中去除全部（100%）或部分（50%）叶子。通过在土壤上方5–7厘米处切割树皮组织，在茎基部接种P.plurivora菌丝体。2016年70天后和365天后（2017年9月下一个生长季节结束时）通过测量病变大小来评估茎损伤。我们发现，下垂B.pendula可以作为土壤传播病原体P.plurivora的宿主，该病原体会导致波兰苗圃桦树幼苗的死亡。结果是。。。

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.
