摘要
在大田栽培条件下,研究了在马铃薯块茎膨大期叶面喷施3种植物生长调节剂DTA-6、S3307、SODM对马铃薯产量、品质及根系生理代谢的影响。结果表明,SODM、DTA-6和S3307处理的马铃薯产量分别比清水对照增加17.4%、8.3%和4.1%;3个处理均降低了马铃薯块茎还原糖含量。SODM处理提高了马铃薯块茎中淀粉、可溶性蛋白、蔗糖含量,S3307处理提高了可溶性蛋白含量。SODM处理可提高马铃薯整个生育期的根系活力,DTA-6处理则对马铃薯块茎形成期的根系活力具有促进作用。综合分析得出,3种植物生长调节剂对提高马铃薯产量、改善品质、有效调控根系的生理代谢均有一定的效果,但以SODM处理效果最好。
In a field experiment, effects of three plant growth substances, Diethyl aminoethyl hexanoate （DTA- 6）, Uniconazole （S3307） and SOD mimics （SODM） were studied on potato yield, quality and its root physiology through foliar application at potato tuber expansion period. The results showed that compared to the control, SODM, DTA-6 and S3307 increased yield by 17.4 %, 8.3 %, and 4.1% respectively. SODM could increase the contents of starch, water-soluble protein and sucrose. S3307 could increase the content of water-soluble protein. Three plant growth substances could decrease the content of reduced sugar. The experiment draw the conclusion that three plant growth substances could improve the quality, yield and activity of root metabolism, but SODM treatment had the best effect.
