摘要
于室内模拟干旱环境条件下，对二年生温州蜜柑胁山盆栽苗叶面喷施２，４－Ｄ，ＰＰ３３３，ＣＣＣ及乙烯利．结果表明，４种抑蒸剂均能增加叶片水势和根系活力，但对气孔开度、蒸腾强度和光合强度的影响因抑蒸剂类型不同而有所差别．综合评价，以ＣＣＣ和ＰＰ３３３抑蒸保湿效果最佳．
Under the controlled drought environmental condition in
greenhouse,2-year-old potted Wakiyame Wase seed lings were foliar-sprayed with four
differtent anti-transpi-rants,2,4-D,PP333,CCC,and ethyene. The result showed that four
treatments effectively keep water from evaporation,and increase leaf water potential and root
vigor,respectively. However,they have influence over stomatal opening,transpiration and
photosynthesis,which indicated difference depending on the anti-transpirant type.BY overall
evaluation,CCC and PP333 are the best.
