      文章摘要：以5个处理的水杨酸喷施甜菜叶片，结果表明：水杨酸植物生长调节剂处理提高了甜菜叶片中生长素和赤霉素的含量，降低了玉米素核苷和脱落酸的含量，同时提高了甜菜叶片、茎的干物质重量。

      Abstr：Sugarbeet leaf was spayed by 5 salicylic acid （SA） treatments. The experimental results indicated that the content of gibberellin （GA3） and auxin （IAA） was increased as spraying SA growth regulator, while content of abscisic （ABA） and zeatin riboside （ZR） was decreased. Moreover, the results showed that the weight of dry leaf and stem of sugarbeet was increased with spraying the growth regulator.
