摘 要: 对照的盆栽细叶结缕草Zoysia tenuifolia经低温(白天1℃,晚上-2℃)胁迫3 d后,或露地草坪在最低温度-3℃的冬季里均枯黄,也不诱导抗冻蛋白;与对照相比,预先用暖地型草坪绿叶生长剂处理的草坪则继续保持绿色,增加了CAT活性和可溶性蛋白质含量,增加了10多条蛋白带的活性(经SDS-PAGE电泳分析),而且增加了Rm 0.51和Rm 0.71两条蛋白带,诱导抗冻蛋白产生。 When the grasses of Zoysia tenuifolia Willd Trin grew under 1℃ / --2℃ (day/night) for 3 d in the climatron and -3℃ of the lowest temperature of the winter in the open lawn, the untreated grasses became yellow and could not induce antifreeze protein. Compared with the control, the grasses pre-treated with "leaf-growing-reagent for warm-season turf" maintained green, increased protein contents, raised the activity of CAT, increased activities of more than 10 protein bands, induced two new protein bands(Band Rm 0. 51 and Band Rm 0. 71), induced to produce antifreeze proteins. We first reported that "leaf-growing-reagent for warm-season turf" could induce the plants, such as Z. tenuifolia,which Could not be acclimated by cold to produce antifreeze protein.
