摘要
该文选用荞麦远缘杂交育成品系‘贵多苦75’为材料,进行40 cm(I)、20 cm(Ⅱ)和10 cm(Ⅲ)留桩高度处理,对再生植株主要农艺性状、产量性状和品质性状进行分析。结果表明:留桩高度40 cm内,留桩高度对再生植株株高、茎叶重、单株粒数、单株产量和产量影响显著;处理I植株的株高、茎叶重、单株粒数、单株产量和产量均显著或极显著高于处理Ⅱ和处理Ⅲ,说明留40 cm高桩有利于再生植株营养器官的生长与产量的形成。‘贵多苦75’种子清蛋白含量>谷蛋白含量>醇溶蛋白含量>球蛋白含量。留桩高度40 cm内,留桩高度对种子总蛋白和谷蛋白影响显著,但对清蛋白、醇溶蛋白和球蛋白含量影响不显著。‘贵多苦75’再生植株种子总黄酮含量在3.17%~3.33%之间,受留桩高度的影响不显著。留桩高度为40 cm时,‘贵多苦75’再生植株产量达到1.5 t·hm^(-2),清蛋白、谷蛋白、醇溶蛋白、球蛋白、总黄酮含量分别达到4.06%、3.26%、1.27%、0.39%、3.33%,具有较高营养价值和药用价值。
‘Guiduoku 75’bred by distant hybridization was selected to investigate the major agronomic traits,yield traits and quality traits in ratooning plants under the 40 cm(I),20 cm(Ⅱ)and 10 cm(Ⅲ)of stubble height treatment.The results indicated that the plant height,shoot weight,grain number per plant,yield per plant and yield in ratooning plants were significantly altered by stubble height when stubble height was less than 40 cm.The values of plant height,shoot weight,grain number per plant,yield per plant and yield in ratooning plants under treatment I were significant or extremely significant higher than those of treatmentsⅡandⅢ,suggesting that higher stubble height is beneficial for vegetative organ growth and yield formation in ratooning plants.‘Guiduoku 75’seeds contained four protein components as albumine content>gluten content>prolamine content>globulin content.The total protein content and gluten content were significantly altered by stubble height,but the albumin content,prolamine content,globulin content were not when stubble height was less than 40 cm.The total flavonoid content in ratooning plants of‘Guiduoku 75’ranged from 3.17%to 3.33%,that was little affected by stubble height.The ratooning plants of‘Guiduoku 75’under 40 cm of stubble height treatment harvested 1.5 t·hm^(-2) seeds that contained 4.06%of albumin content,3.26%of gluten content,1.27%of prolamine content,0.39%of globulin content and 3.33%of total flavonoid content,exhibiting high nutritional value and medicinal value.
