Measurements of chlorophyll a fluorescence, nutrient and trace elements, total protein content and malonyldialdehyde in leaves of Arabidopsis thaliana between 1 and 192 h after treatment with 0, 1 or 3 mM 2-3H-benzoxazolinone (BOA), together with imaging of chlorophyll a fluorescence and of the distributions of hydrogen peroxide and superoxide anion, suggested that the primary phytotoxic action of BOA is the induction of premature senescence, and that oxidative stress is a secondary effect that sets in a day or two later.
对用 0、1 或 3mM 2-3H-苯并恶唑酮（BOA）处理 1 到 192 小时后的拟南芥叶片中的叶绿素 a 荧光、营养和微量元素、总蛋白含量和丙二醛进行测量，并对叶绿素 a 荧光和过氧化氢及超氧阴离子分布进行成像，结果表明 BOA 的主要植物毒性作用是诱导过早衰老，而氧化应激是两天后才出现的继发效应。
