摘　　要：为筛选出适宜生产苦荞芽菜的优质品种,选用24个凉山彝族自治州推广栽培苦荞品种作为供试材料,于人工智能气候箱中培养[温度25℃、16 h(光)/8 h(暗),湿度75%]生长10 d收获,对苦荞芽长、茎粗、鲜重、芽菜比4个生长指标和总黄酮、总酚、可溶性蛋白、DPPH自由基清除能力4个品质指标测定分析。采用隶属函数法对24个品种8个指标进行综合分析评价。结果得出,24个苦荞芽菜中芽长最长的是‘昭苦2号’(12.34 mm),茎粗最大的是‘西荞6号’(0.13 mm),单株鲜重最重的是‘云苦1号’(0.252 g),芽菜比最大的是‘西荞2号’(7.07),总黄酮含量最高的是‘九江苦荞’(16.56 mg/g),可溶性蛋白含量最高的是‘晋苦荞12号’(129.5 mg/g),总酚含量最高的是‘迪苦1号’(2.66 mg/g),DPPH自由基清除能力最大的是‘西荞4号’(77.6%)。由隶属函数综合分析可知,24个苦荞品种中‘九江苦荞’隶属函数值最高(0.7436),是最适宜加工芽菜的优质品种;‘川荞1号’隶属函数值最小(0.2219),不适宜加工芽菜。The main objective of this work was to select tartary buckwheat cultivars suitable for sprout production.Twenty-four cultivars were selected from Liangshan Autonomous Prefecture as test materials,those were placed in the climate incubator(25℃,light 16 h/dark 8 h,humidity 75%),and harvested at 10th day,and then their growth indexes(plant length,stem diameter,fresh weight,the rate of sprout fresh weight and seed dry weight)and quality indexes(total flavonoid,total phenol,soluble protein and DPPH radical scavenging abilities)were determined.The results showed that the longest plant length was recorded in‘Zhaoku No.2’(12.34 mm);the widest stem diameter was observed in‘Xiqiao No.6’(0.13 mm),the heaviest fresh weight was recorded in‘Yunku No.1’(0.252 g/plant).The maximum value was estimated in the rate of fresh sprout weight and seed dry weigh of‘Xiqiao No.2’(7.07).The highest content of total flavonoid was recorded in‘Jiujiangkuqiao’(16.56 mg/g),and the maximum content of soluble protein was‘Jinkuqiao No.12’(129.5 mg/g).The maximum value of total phenol content was recorded in‘Diku No.1’(2.66 mg/g),the highest value of DPPH radical scavenging abilities was found in‘Xiqiao No.4’(77.6%).And then the growth indexes and quality indexes of 24 tartary buckwheat cultivars were evaluated by the subordinate function value method,the maximum subordinate function value was observed in‘Jiujiangkuqiao’(0.7436),the minimum subordinate function value was recorded in‘Chuanqiao No.1’(0.2219)in the 24 cultivars.The above results indicate that‘Jiujiangkuqiao’has a high overall score and the most suitable for the sprout production,but‘Chuanqiao No.1’is not suitable for the sprout production in 24 cultivars.
