| 摘 要： | 研究了4种注干液剂(吡虫啉、啶虫脒、吡虫啉·敌敌畏和敌敌畏·氧乐果)树干注射后对垂柳叶片内几种生理指标的影响。结果表明:4种药剂树干注药后均可导致垂柳叶片内可溶性总糖及纤维素含量下降,下降程度与药剂种类及注药后时间长短有关。吡虫啉对可溶性总糖含量影响最显著,药后 6 d下降了28.31%;敌敌畏·氧乐果对纤维素含量影响最显著,药后 6 d下降了19.16%。4种药剂注药后短期内均可导致叶绿素、可溶性蛋白和淀粉含量下降,但随处理时间延长其含量又明显上升。其中吡虫啉对叶绿素含量影响最显著,药后15 d升高了21.31%;敌敌畏·氧乐果对可溶性蛋白、淀粉含量影响最显著,药后15 d分别上升24.94%和 20.32%。

| Abstract: | The effects of 4 liquid formulations(imidacolprid,acetamiprid,imidacloprid DDVP and DDVP omethoate) on some physiological indices in weeping willow(Salix babylonica Linn) leaves by trunk injection were reported.The results showed that all of the(4 pesticides) caused the decreasing of the amount of total soluble sugar and cellulose in willow leaves after treatments.The decreasing degree varied with the type of pesticides and the time after treatment.Among 4 pesticides,imidacolprid seriously effected on the content of total soluble sugar,the content was reduced 28.31% at 6 d after trunk injection; DDVP omethoate seriously effected on the content of cellulose,the content was reduced 19.16% at 6 d after trunk injection.All of the 4 pesticides caused the decreasing of the amount of chlorophyll,soluble protein and starch in willow leaves in a short time after treatments,but the amount was increased along with the (time.Among) 4(pesticides,)imidacolprid seriously effected on the content of(chlorophyll,the) content was increased(19.70%) at 15 d after trunk(injection;DDVP )omethoate seriously effected on the content of soluble protein and(starch,)the content was increased(24.94%) and 20.32% at 15 d after trunk injection. |
