高寒黑土区植物激活蛋白(VDAL)对马铃薯产量和品质的影响
The Effect of Plant Activating Proteins(VDAL)on Potato Yield and Quality in High Cold Black Soil Regions
摘要
Abstract
To investigate the application effect of plant activating protein(VDAL)in potato production and screen out the most suitable appli-cation method of VDAL,the effects of VDAL on the yield and quality of potato seed tubers under different application methods were compared for two consecutive years from 2022 to 2023.The results showed that the effects of different VDAL treatments on potato yield showed extremely significant differences.The highest yield was achieved by foliar spraying(F),with an average yield of 68.64 t/hm2,which was significantly higher than CK;the commercial potato rate remained between 80%and 92%,with foliar spraying and seed dressing(FS)having the highest commercial potato rate,but there was no significant difference compared to other treatments;the dry matter content and protein content showed extremely significant differences,with leaf spraying+seed dressing(FS)having the highest dry matter and protein content,at 16.79%and 1.87%,respectively,which were significantly higher than the other treatments;there was a significant difference in reducing sugar content,with foliar spraying+seed dressing(FS)being the highest and significantly higher than foliar spraying(F),but there was no significant differ-ence compared to CK;the vitamin C content was maintained at 0.13-0.14 mg/g,and CK was significantly higher than foliar spraying(F),but no significant difference was observed;the starch content remained between 14.18%and 15.43%,and foliar spraying(F)was the high-est,but there was no significant difference compared to other treatments.In summary,the application of VDAL can significantly improve the yield indicators of potatoes and the dry matter content,protein content,and starch content of tubers.The most suitable application method is foliar spraying of VDAL(F).关键词
