摘要： 为探究乙偶姻对菠菜生长及食用品质的调控效应，采用盆栽试验方法，设置根部浇灌0.05、0.10、0.15、0.20、0.25 g/L乙偶姻溶液，以及叶面喷施0.15 g/L乙偶姻溶液，并以根部浇灌蒸馏水作为空白对照(CK)，测定各处理下菠菜生长指标与品质参数。结果表明，外源乙偶姻处理可显著促进菠菜植株生长并提升部分品质指标。其中，根部浇灌0.15 g/L处理显著提高了菠菜株高与鲜重产量(P<0.05)，且叶面喷施方式的效果优于根部浇灌(P<0.05)。根部浇灌0.05 g/L乙偶姻显著促进了根系生长(P<0.05)。在品质方面，0.15、0.25 g/L处理下叶片叶绿素、维生素C含量最高(P<0.05)，而0.05、0.20 g/L处理则显著降低了草酸、硝酸盐含量(P<0.05)。比较不同施用方式发现，叶面喷施处理下菠菜叶绿素与维生素C含量显著低于根部浇灌(P<0.05)，草酸与硝酸盐含量则显著较高(P<0.05)，表明叶面喷施可能不利于食用品质的提升。综上，叶面喷施0.15 g/L乙偶姻可作为提高菠菜生物量的有效农艺措施；若以改善食用品质为目标，则推荐采用根部浇灌方式；在促进根系发育的育苗或抗逆栽培中，根部浇灌0.05 g/L乙偶姻具有应用潜力。

Abstract:

To investigate the regulatory effects of exogenous acetoin on the growth and edible quality of spinach, a pot experiment was conducted with six treatment groups. These included root irrigation with acetoin solutions at concentrations of 0.05, 0.10, 0.15, 0.20, and 0.25 g/L, foliar spraying with acetoin solution at 0.15 g/L, and a control (CK) involving root irrigation with distilled water. Growth indices and quality parameters of spinach were systematically measured under each treatment. The results indicated that exogenous acetoin application significantly enhanced plant growth and modulated specific quality traits. The root irrigation with 0.15 g/L acetoin notably increased plant height and fresh weight yield (P<0.05), with foliar spraying demonstrating a stronger effect than root irrigation (P<0.05). Root irrigation with 0.05 g/L acetoin significantly promoted root growth (P<0.05). Regarding quality, leaf chlorophyll and vitamin C contents were highest under the 0.15 and 0.25 g/L treatments (P<0.05), whereas oxalic acid and nitrate contents were most effectively reduced by the 0.05 and 0.20 g/L treatments (P<0.05). Comparative analysis of application methods revealed that foliar spraying resulted in significantly lower chlorophyll and vitamin C levels, but higher oxalic acid and nitrate levels compared to root irrigation (P<0.05), suggesting that foliar application may be less favorable for improving edible quality. In conclusion, foliar spraying of 0.15 g/L acetoin represents an effective agronomic strategy for enhancing spinach biomass. For the purpose of improving edible quality, root irrigation is recommended. Furthermore, root irrigation with 0.05 g/L acetoin shows potential for applications aimed at promoting root development, such as in seedling cultivation or stress resistance.
