torvum是一种野生茄属植物，被广泛用作砧木，并因其对几种病原体和害虫的抗性而闻名，包括根结线虫（RKN,Meloidogynespp.）。毒性失误。在一些旋律雌性物种中观察到torvum，如asM。差异,butM。从日本分离的单种群尚未进行寄生检测。我们进行了接种试验。番茄栽培品种及防治植物(茄；番茄)用日本的em接种。单种群，然后根据虫卵数量评估寄主适宜性。试验是在小型塑料盆中使用苗圃植物进行的。第一项实验揭示了这一点。在日本市售的玉米品种对toM敏感。差异。在第二次实验中，三个em。从地理位置较远的地区获得的单种群产生了大量的卵细胞。torvumroots。帖前。所有品种均对toM具有抗性。在这两种试验中，不为人知的，作为一种对照种。我们对m .的每粒卵的卵数进行了检查。我证明了s。接种两种菌种。单居群显著低于s。番茄属植物，这表明番茄属植物的繁殖力有一定差异。单倍体取决于寄主植物。一系列实验揭示了日本em的毒力和繁殖能力。haplapopulations失误。torvum，构成潜在的风险。杀虫剂不能抑制RKN在这类害虫侵染下的危害。
Solanum torvum, a wildSolanumspecies, is widely used as a rootstock and is known for its resistance to several pathogens and pests including root‐knot nematode (RKN,Meloidogynespp.). Virulence toS. torvumwas observed in severalMeloidogynespecies such asM. hapla, butM. haplapopulations isolated from Japan have not been tested for parasitism. We performed inoculation assays onS. torvumcultivars and control plants (S. melongena, eggplant;S. lycopersicum, tomato) inoculated with JapaneseM. haplapopulations, and we then evaluated the host suitability based on the eggmass number. The assays were carried out using nursery plants in small plastic pots. The first assay revealed thatS. torvumcultivars that are commercially available in Japan were susceptible toM. hapla. In the second assay, threeM. haplapopulations obtained from geographically distant areas produced a number of eggmasses onS. torvumroots. TheS. torvumcultivars were all resistant toM. incognita, as a control species ofMeloidogyne, in both assays. Our examination of the number of eggs per eggmass ofM. haplademonstrated that the values ofS. torvumunder inoculation of twoM. haplapopulations were significantly lower than those ofS. lycopersicum, implying some difference in the fecundity ofM. hapladepending on the host plants. The series of experiments revealed the virulence and reproductivity of JapaneseM. haplapopulations toS. torvum, posing a potential risk thatS. torvumcannot suppress RKN damage in agricultural fields under infestation of suchMeloidogynespecies.
