| 摘 要： | 对雾培马铃薯植株叶片喷施烯效唑研究表明:5￣20mg·L-1的烯效唑可显著降低株高,增加茎粗,扩大叶面积,增加根系和匍匐茎长度,同时,降低植株地上鲜重和整株鲜重。说明烯效唑具有控上促下的作用,可促进叶片光合产物更多向植株的地下部分输送,有利于小薯膨大和产量的提高。叶片喷施5￣15mg·L-1烯效唑均可提高马铃薯小薯产量,其中以5mg·L-1增产作用最显著。 |

| Abstract: | The leaves of potato plant cultured by the aeroponics were treated with the different concentrations of uniconazole (5 mg·L-1,10 mg·L-1,15 mg·L-1, and 20 mg·L-1). There was a decrease in the plant height and the fresh weight of overall plant and aboveground, while there was an increase in the stem width and leaf area, and in the length of root and stolon. The results indicated that uniconazole could inhibit the growth of the aboveground of potato plant cultured by aeroponics, and improve the underground, which means that carbohydrate in the leaf could be rapidly transferred to the tuber, then enhance the number of minituber. Dosage of 5 mg·L-1 gave the most significant yield increase. |
