- 摘要:
- 为解决齐齐哈尔市主栽马铃薯品种单产较低的问题,在大田条件下,以马铃薯尤金品种和克新13品种为试验材料,对比在初花期进行叶面喷施10、20、30、40、50 mg·L1烯效唑(Uniconazole,简称S3307)和播种前用 10、50、100、150、200 mg·L1赤霉素(Gibberellin)GA3浸种处理对商品薯产量的调控效应。结果表明:S3307在10~40 mg·L1的浓度下,GA3在10~50 mg·L1的浓度下均能增加马铃薯的商品薯产量,但S3307的增产效果要优于GA3,S3307在两个品种上的增产幅度均在20%以上,而GA3的增产幅度均在10%以上。且不同品种间对植物生长调节剂的敏感程度也不一样,克新13对浓度的范围敏感度要高于尤金品种。
- Abstract:
- In order to solve the problem of low yield per unit area of main potato cultivars in Qiqihar City,under field conditions,Eugene and Kexin 13 cultivars were used as experimental materials to spray 10,20,30,40 and 50 mg·L1 Uniconazole (S3307) on leaves and soak 10,50,100,150,200 mg·L1 GA3 seeds before sowing.Regulation effect on commercial potato yield was studied.The results showed that under the concentration of 1040 mg·L1 S3307,the concentration of 1050 mg·L1 GA3,both could increase the yield of commercial potatoes,but the yieldincreasing effect of S3307 was better than GA3.The yield of S3307 was increased by more than 20% in both varieties,while that of GA3 was increased by more than 10%.The sensitivity to plant growth regulators was also different among different varieties.The sensitivity of Kexin 13 to the range of concentration was higher than that of Eugene.
