An experiment was conducted to determine whether wild accessions and cultivars ofLycopersicon esculentum Mill. differed in inherent morphological, physiological or phenological traits and whether such differences would result in variation in response to vesicular-arbuscular mycorrhizal infection. While distinctions between wild accessions and cultivars were apparent (the cultivars generally had higher phosphorus use efficiencies and shorter lifespans than the wild accessions) and the cultivars were, as a group, more responsive to mycorrhizal infection than the wild accessions, there was significant variation among wild accessions and among cultivars in response to infection. Regardless of cultivation status, non-mycorrhizal plant root density was significantly negatively correlated with response to infection. Phosphorus use efficiency was generally not significantly correlated with response to infection. Mycorrhizal infection decreased phosphorus use efficiency in all accessions, but had variable effects on root density, depending upon accession and time. Finally, the vegetative response was not necessarily of the same magnitude as the reproductive response.
进行了一项实验，以确定野生番茄和栽培番茄在固有形态、生理或物候特征上是否存在差异，以及这些差异是否会导致泡囊丛枝菌根感染反应的变化。虽然野生番茄和栽培番茄之间的区别很明显（栽培番茄通常比野生番茄具有更高的磷利用效率和更短的寿命），并且作为一个群体，栽培番茄比野生番茄对菌根感染更敏感，但野生番茄之间和栽培番茄之间在感染反应上存在显著差异。无论种植状态如何，非菌根植物的根密度与感染反应呈显著负相关。磷利用效率通常与感染反应没有显著相关性。菌根感染降低了所有番茄品种的磷利用效率，但对根密度的影响因品种和时间而异。最后，营养反应的程度不一定与生殖反应相同。
