概括

俄勒冈州的苗圃植物,如树和树,容易受到根结线虫 (Meloidogyne incognita,Meloidogyne hapla) 和病变线虫 (Pratylenchus neglectus) 的感染. 木 (Buxus sempervirens) 显示出对Pratylenchus neglectus的耐药性.

科学领域:

植物病理学植物病理学
遗体学遗体学是一个学科.
园艺园艺园艺园艺

背景情况:

俄勒冈州是美国领先的苗圃生产州,特别是树和灌木.
植物寄生性线虫对苗圃种群构成重大生长和植物卫生风险.

研究的目的:

确定关键的装饰树木和灌木对常见的植物寄生虫线虫的宿主地位.
在幼儿园环境中识别Meloidogyne incognita,Meloidogyne hapla和Pratylenchus neglectus的潜在宿主.

主要方法:

温室实验评估了四棵树 (Quercus alba,Quercus garryana,Acer campestre,Thuja occidentalis) 和两棵灌木 (Buxus sempervirens,Rhododendron catawbiense) 的生长情况.
植物接种了M.隐形菌,M.哈普拉菌或P.neglectus的疫苗.
经过三个月的时间,在土壤和根部中量化了虫的密度,以计算最终的种群 (Pf) 和生殖因子 (RF).

主要成果:

所有测试的树木和灌木,除了Buxus sempervirens,都对M. incognita和M. hapla敏感,其中Acer campestre对M. incognita的敏感性最高 (RF=28.4).
所有的植物,除了常春 (Buxus sempervirens),都是P. neglectus的良好的宿主.
巴克斯 (Buxus sempervirens) 呈现出对P. neglectus的非宿主状态 (RF ≈ 0).

结论:

据报道,Quercus alba,Quercus garryana和Acer campestre是M. incognita,M. hapla和P. neglectus的新发现的宿主.
图西和Rhododendroncatawbiense是P.neglectus的新报告的宿主.
Buxus sempervirens被证实是P. neglectus的非宿主,这表明其在线虫管理策略中的潜在用途.

Epiphytes, Parasites, and Carnivores

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...
