Plant resistance to herbivores was induced in a field experiment to evaluate the consequences of induced responses for subsequent herbivory and plant fitness. Induction early in the season resulted in halving of herbivory by chewing herbivores and a reduction in the abundance of phloem-feeding aphids when compared with controls. A correlate of lifetime plant fitness, seed mass, was enhanced by over 60 percent for individuals that were induced.
在一项田间试验中诱导了植物对食草动物的抗性，以评估诱导反应对后续食草作用和植物适合度的影响。与对照相比，季节早期的诱导使咀嚼式食草动物造成的食草量减半，并且吸食韧皮部的蚜虫数量减少。对于被诱导的个体，作为植物一生适合度相关指标的种子质量提高了60%以上。
