摘要:
为评价不同生长调节剂对甘薯块根产量及品质的影响,本研究以徐薯18和龙薯9号2个甘薯品种为试验材料,以喷施清水为对照(CK),进行不同质量浓度的烯效唑(S3307)、2，4-表油菜素内酯(EBR)和聚谷氨酸(PGA)的叶面喷施处理,分析不同质量浓度和类型生长调节剂对甘薯产量与品质的影响。结果表明: 0.05 mg/L EBR处理徐薯18和龙薯9号的产量分别比CK提高58.86%和52.68%；105mg/L PGA处理徐薯18块根可溶性蛋白含量、薯肉总酚含量、薯肉类黄酮含量分别比CK增加62.60%、86.49%、63.64%,105mg/L PGA处理龙薯9号块根可溶性总糖含量、淀粉含量、可溶性蛋白含量、维生素C含量、薯皮花青素含量及薯肉花青素含量均显著高于CK。75 mg/L S3307处理徐薯18和龙薯9号块根淀粉含量均显著高于CK,100 mg/L S3307处理徐薯18和龙薯9号块根可溶性总糖含量分别比CK增加37.48%和65.27%。综上,适宜质量浓度的S3307、EBR和PGA能显著提升徐薯18和龙薯9号的产量及品质指标,但相同生长调节剂处理下不同品种甘薯产量和品质指标的提升效果存在较大差异,生产中应根据产品需求选择具体的生长调节类型与剂量。
Abstract:
In order to evaluate the effects of different growth regulators on the tuber yield and quality of sweet potato, two sweet potato varieties, Xushu 18 and Longshu 9, were used as experimental materials, and water was sprayed as control (CK). Different concentrations of uniconazole (S3307), 2,4-epibrassinolide (EBR) and polyglutamic acid (PGA) were sprayed on the leaves, and the effects of different concentrations and types of growth regulators on the yield and quality of sweet potato were analyzed. The results showed that the yield of Xushu 18 and Longshu 9 treated with 0.05 mg/L EBR was 58.86% and 52.68% higher than that of CK, respectively. The soluble protein content, total phenol content and flavonoid content in tubers of Xushu 18 treated with 105 mg/L PGA increased by 62.60%, 86.49% and 63.64%, respectively, compared with CK. The total soluble sugar content, starch content, soluble protein content, vitamin C content, anthocyanin content in tuber skin and anthocyanin content in tuber flesh of Longshu 9 treated with 105 mg/L PGA were all significantly higher than those of CK. Starch content in tubers of Xushu 18 and Longshu 9 treated with 75 mg/L S3307 was significantly higher than that of the CK. Soluble sugar content in tubers of Xushu 18 and Longshu 9 treated with 100 mg/L S3307 increased by 37.48% and 65.27%, respectively. In summary, the appropriate concentrations of S3307, EBR and PGA can significantly improve the yield and quality indicators of Xushu 18 and Longshu 9, but there are great differences in the improvement effect of yield and quality indicators of different varieties of sweet potato under the same growth regulator treatment. In production, specific growth regulation types and dosages should be selected according to product requirements.
