Effect of Seed Coating on Carbon Metabolism and Yield of Adzuki Bean

试验采用Ⅰ型生物种衣剂(T1)、Ⅱ型生物种衣剂(T2)和化学种衣剂(T3)处理红小豆种子,研究种衣剂对红小豆碳代谢和产量的影响。结果表明:Ⅰ型生物种衣剂和化学种衣剂处理在分枝期显著降低株高,Ⅱ型生物种衣剂在分枝期及开花结荚期显著增加株高;所有种衣剂处理在幼苗期显著降低淀粉含量,在分枝期显著增加蔗糖和总糖含量;Ⅰ型生物种衣剂和化学种衣剂处理的红小豆单株粒数分别提高29.48%、71.91%,Ⅱ型生物种衣剂处理降低25.8%;Ⅱ型生物种衣剂和化学种衣剂处理显著降低百粒重;Ⅰ型生物种衣剂、化学种衣剂处理分别增产29.69%、23.32%。这表明Ⅰ型生物种衣剂能有效优化红小豆的生长状况,增加产量。该研究为红小豆的品质改良和生物种衣剂在杂粮方面的应用提供了前期理论依据。

The test was carried out by using type Ⅰ biological seed coating agent(T1),type Ⅱ biological seed coating agent(T2)and chemical seed coating agent(T3)to study the effect of seed coating agent on carbon metabolism and yield of red bean.The test showed that the treatment of type Ⅰ biological seed coating agent and chemical seed coating agent significantly reduced the plant height during the branching stage,and the type Ⅱ biological seed coating agent significantly increased the plant height during the branching stage and flowering and pod-forming stage;all the coating agents were treated at The seedling stage significantly reduced the starch content,and significantly increased the sucrose and total sugar content during the branching period;the number of grains of the red bean per plant treated by the type Ⅰ biological seed coating agent and the chemical seed coating agent increased by 29.48%and 71.91%,respectively.The treatment of the coating agent was reduced by 25.8%;The treatment of the type Ⅱ biological seed coating agent and the chemical seed coating agent significantly reduced the 100-grain weight;the treatment of the type Ⅰ biological seed coating agent and the chemical seed coating agent increased the yield by 29.69%and 23.32%,respectively.This indicates that the type Ⅰ biological seed coating agent can effectively optimize the growth of red bean and increase the yield.This study provides a preliminary theoretical basis for the quality improvement of red bean and the application of biological seed coating in the direction of miscellaneous grains.
