摘　　要：分别设置0、0.05 g·L^-1、0.1 g·L^-1、0.2 g·L^-1、0.4 g·L^-1和0.8 g·L^-1等6个浓度FeSO 4溶液,分析FeSO 4浸种对小麦芽苗菜生长、生理活性物质及小麦Fe积累的影响。结果表明,0.05~0.1 g·L^-1浓度浸种显著提高了小麦芽苗菜的干鲜重,0.05~0.2 g·L^-1浓度浸种对氧化物酶活性有促进作用,0.05~0.4 g·L^-1浓度显著提高了丙二醛和可溶性糖含量,≥0.4 g·L^-1浓度对叶绿素a和叶绿素b含量有一定的抑制作用,但对维生素C和可溶性蛋白含量影响较小。≥0.1 g·L^-1浓度浸种显著增加了Fe含量,且单株Fe积累量明显增加。研究表明,0.1 g·L^-1 FeSO 4浸种有利于增加小麦芽苗菜干鲜重及Fe积累量,提升了生理活性物质,可作为潜在的富铁营养强化的措施。In this study,the effects of soaking seed with different concentrations(0,0.05 g·L^-1,0.1 g·L^-1,0.2 g·L^-1,0.4 g·L^-1 and 0.8 g·L^-1 respectively)FeSO 4 solution on the growth,physiological activators and Fe accumulation of wheat sprouts,physiological activators and Fe accumulation in wheat were analyzed.The results showed that the dry and fresh weight of wheat sprouts was significantly increased by soaking seeds with a concentration of 0.05-0.1 g·L^-1,while oxidase activities were promoted by soaking seeds with a concentration of 0.05-0.2 g·L^-1.Meanwhile,the content of malondialdehyde(MDA)and soluble sugar were both significantly increased by soaking seeds with a concentration of 0.05-0.4 g·L^-1.And,the contents of chlorophyll A and chlorophyll B were inhibited to some extent when the FeSO 4 concentration≥0.4 g·L^-1,but there were little effect on the contents of vitamin C and soluble protein.Additionally,the soaking seeds with FeSO 4 concentration≥0.1 g·L^-1 increased Fe content significantly and Fe accumulation per plant increased significantly.In general,the soaking seeds with 0.1 g·L^-1 FeSO 4 solution is beneficial to increase the dry fresh weight and Fe accumulation of wheat sprouts,improve physiological activators,and can be used as a potential fortification measure of iron-rich nutrition.
