摘要：

The hypothesis that rapid gamma-aminobutyrate (CABA) accumulation is a plant defense against phytophagous insects was investigated. Increasing CABA levels in a synthetic diet from 1.6 to 2.6 mu mol g(-1) fresh weight reduced the growth rates, developmental rates, and survival rates of cultured Choristoneura rosaceana cv Harris larvae. Simulation of the mechanical damage resulting from phytophagous activity increased soybean (Glycine max L.) leaf CABA 10- to 25-fold within 1 to 4 min. Pulverizing leaf tissue resulted in a value of 2.15 (+/-0.11 se) mu mol GABA g(-1) fresh weight.
