摘　　要：为探究不同蚕豆品种在不同生育期的结瘤特性和根瘤豆血红蛋白含量与产量的关系,以14个不同蚕豆品种(系)为试验材料,分别于盛花期、结荚期、鼓粒期和成熟期测定蚕豆的根瘤结瘤特性及根瘤豆血红蛋白含量,于成熟期测定蚕豆产量,并分析根瘤数量、鲜重、干重、豆血红蛋白含量的变化规律及其与产量的相关性。结果表明:在盛花期至成熟期,不同蚕豆品种(系)的根瘤数量、豆血红蛋白含量总体呈递减趋势,根瘤鲜重、干重总体呈先增高后下降趋势;在14个蚕豆品种(系)中,青蚕15号的产量最高(7642.96 kg/hm 2),是其他品种(系)的1.1~2.4倍,与其他13个品种(系)之间存在极显著差异;鼓粒期与成熟期的根瘤数量、鲜重和干重分别是调控根瘤豆血红蛋白含量的关键因子,成熟期的根瘤干重、鲜重、数量及豆血红蛋白含量均与产量极显著正相关,是调控蚕豆产量的重要因子。该研究结果可为选育高固氮蚕豆品种(系)提供科学依据。A total of 14 fava bean varieties(lines)are taken as materials to explore the nodule cha-racteristics and the relationship between nodule leginhemoglobin content and yield of fava bean at different growth stages.Their nodule characteristics and nodule leginhemoglobin content are measured during the flowering,podding,bulging and mature stages.The yield is measured during the mature stage.The variations in nodule quantity,fresh weight,dry weight and leginhemoglobin content are analyzed,as well as their correlation with yield.The results indicate that from the flowering stage to the mature stage,the numbers of root nodules and the leginhemoglobin content of different faba bean varieties(lines)show an overall decreasing trend,while the fresh weight and dry weight of root nodule show an overall increasing trend,followed by a decreasing trend.Among the 14 varieties,Qingcan 15 has the highest yield(7642.96 kg/hm 2),which is 1.1~2.4 times higher than the other 13 varieties(lines),indicating a significant difference between Qingcan 15 and the other 13 varieties.The number,fresh weight and dry weight of root nodule during the bulging and mature stages are the key factors regulating the content of root nodule leginhemoglobin.The dry weight,fresh weight,quantity and leginhemoglobin content of mature root nodule are significantly positively correlated with yield,which are important factors in regulating the yield of faba bean.The research results provide scientific basis for the breeding of high nitrogen fixing faba bean varieties(lines).
