Differences in Growth and Metabolics between Hydroponic and Peat Soil Cultivation Anoectochilus roxburghii
摘要
Abstract
The aim of the study was to systematically compare the differences in growth indexes and quality components between hydroponics and soil cultivation for 30 days and 90 days,and to investigate the main differential metabolic pathways of Anoectochilus roxburghii.The results showed that comparing with soil cultivation,the root length of hydroponics increased significantly on 30th day,and the root length and leaf area increased significantly on 90th day,but the stem thickness decreased.The net photosynthetic rate increased significantly on 30th day of hydroponics,and the chlorophyll content increased significantly on 90th day of hydroponics.In terms of components,total flavonoids and kinsenoside increased significantly on 30th day of hydroponics,and aspartic acid,γ-aminobutyric acid,and hydroxyproline decreased significantly;aspartic acid,asparagine,γ-aminobutyric acid,and methionine decreased significantly on 90th day of hydroponics.On metabolic pathways,lipid,flavonoid and flavonol biosynthesis,diterpene and secondary metabolic biosynthesis were significantly up-regulated on 30th day,and lipid and secondary metabolic pathways were significantly up-regulated,while diterpene biosynthesis underwent a down-regulation on 90th day in the hydroponically grown group compared to the soil-grown group on 30th day and 90th day.关键词
