叶面喷施微量元素对生姜生理特性及姜辣素积累的影响
Effects of foliar application of trace elements on physiological characteristics and gingerols accumulation in ginger
摘要
Abstract
[Objective]This study aimed to investigate the effects of foliar application of different types and concentrations of trace elements on the physiological metabolism and quality formation of ginger,so as to provide a theoretical basis for the rational application of trace elements in high-quality and high-yield ginger cultivation.[Method]Foliar sprays of sodium molybdate,sodium tetraborate,and manganese sulfate solutions at different concentrations were applied.Changes in chlorophyll content,soluble protein content,soluble sugar content,antioxidant enzyme activities in ginger leaves,as well as the contents of curcumin and gingerols in the rhizomes were analyzed.[Result]The results showed that appropriate concentrations of trace elements effectively promoted the synthesis of photosynthetic substances in ginger leaves.Treatments with 0.3%molybdenum(Mo),boron(B),and manganese(Mn)all significantly increased chlorophyll content.However,the optimal concentrations for the accumulation of soluble protein and soluble sugar varied depending on the element.The three trace elements significantly regulated the activities of antioxidant enzymes in the leaves.All 0.1%treatments significantly enhanced peroxidase(POD)activity,while all treatments inhibited catalase(CAT)activity.All three trace elements inhibited the accumulation of curcumin but significantly promoted the synthesis of gingerols.Among them,the treatments with 0.3%sodium molybdate,0.3%sodium tetraborate,and 0.2%manganese sulfate had the most significant promoting effects on gingerols content.[Conclusion]Foliar application of sodium molybdate,sodium tetraborate,and manganese sulfate can effectively regulate the physiological metabolism of ginger.By influencing photosynthesis,osmotic regulation substances,and the antioxidant system,these treatments ultimately promote the synthesis of gingerols,the key flavor compounds in ginger.关键词
