Weeds did not appear to serve as reservoirs for phytophagous Louisiana sugarcane nematode populations except for Criconemella spp., Meloidogyne spp., Tylenchorhynchus annulatus, and total phytophagous nematode densities were lower on weed-stressed cane and were accompanied by reduced accumulations of free cysteine, proline, and 13 other free amino acids in sugarcane. A significant weed-virus interaction for sugarcane free cysteine accumulation was detected; T. annulatus populations were highly correlated (r = 0.59, P </= 0.001) with the weed-induced and virus-induced changes in free cysteine. Sugarcane nematodes interacted differently with the weed and virus stresses and changes in host plant stress-related free amino acid concentrations.
除环线短体线虫属、根结线虫属、环形泰勒线虫外,杂草似乎并非植食性路易斯安那甘蔗线虫种群的宿主,并且在受杂草胁迫的甘蔗上,植食性线虫的总密度较低,同时甘蔗中游离半胱氨酸、脯氨酸和其他13种游离氨基酸的积累量也减少。检测到杂草与病毒对甘蔗游离半胱氨酸积累存在显著的相互作用;环形泰勒线虫种群与杂草诱导和病毒诱导的游离半胱氨酸变化高度相关(r = 0.59,P≤0.001)。甘蔗线虫与杂草和病毒胁迫以及宿主植物胁迫相关游离氨基酸浓度变化的相互作用方式不同。
