Fall annual leaf senescence of peach was delayed in the field and in microplots in the presence of Criconemella xenoplax. Soil from the rhizosphere of orchard trees with greener leaves had ca. 2.5 x more nematodes than soil around trees in a more advanced state of fall senescence. In microplots, monoclonal antibody enzyme immunoassay (EIA) of leaf cytokinins indicated that concentration of zeatin riboside-like substances and chlorophyll content were greater in leaves of trees growing in nematode-infested soil than in trees in uninfested soil. EIA also indicated the presence of substances resembling trans-zeatin, zeatin riboside, dihydrozeatin, and dihydrozeatin riboside-like substances in whole body homogenates of C. xenoplax. Levels of zeatin-like substances were present in the nematode in greater levels than the other related substances.
在田间以及存在奇异小环线虫（Criconemella xenoplax）的小区试验中，桃树秋季叶片衰老被延迟。与处于秋季衰老更高级阶段的树木周围土壤相比，叶片更绿的果园树木根际土壤中的线虫数量大约多2.5倍。在小区试验中，对叶片细胞分裂素进行的单克隆抗体酶免疫分析（EIA）表明，生长在有线虫侵染土壤中的树木叶片中，玉米素核苷样物质的浓度和叶绿素含量高于未侵染土壤中的树木。EIA还表明，在奇异小环线虫的全身匀浆中存在类似反式玉米素、玉米素核苷、二氢玉米素和二氢玉米素核苷样物质。线虫体内玉米素样物质的含量高于其他相关物质。
