2、期内源激素含量的差异及其与苦荞产量和品质的关系,以四川本地4种苦荞品种西荞1号、米荞1号、川荞1号和川荞2号为试验材料,对比2种栽培方法下4种苦荞的内源激素含量、产量和营养品质;测定其在常规栽培方法和新型栽培技术(发明专利申请号201610057193.3,公开号105660133A)下苦荞的单株粒重、千粒重、产量、膳食纤维、蛋白质、黄酮和淀粉的含量,以及其成熟期茎、叶、根中脱落酸(ABA)、玉米素+玉米素核苷、生长素(IAA)、1-氨基环丙烷-1-羧酸(ACC)和多胺(腐胺、亚精胺、精胺)等内源激素的含量,并进行相关性分析。结果显示,
3、4种苦荞的膳食纤维、蛋白质、黄酮及淀粉含量与苦荞叶中的ABA含量呈显著负相关;蛋白质含量与叶、根中的玉米素+玉米素核苷及IAA含量呈显著或极显著正相关;黄酮含量与叶中的IAA、ACC和多胺的含量呈显著或极显著正相关。表明苦荞的产量和品质与其不同部位间的内源激素含量有密切关系,并且可以通过新型栽培技术调节其内源激素含量,以达到改善苦荞品质和产量的目的。关键词:苦荞;内源激素;栽培技术;产量;品质中图分类号:S517文献标识码:A文章编号:1672352X(2017)04073206Effectsofdifferentcultivat
