Effects of different exogenous regulators on cultivated Ginseng Radix et Rhizoma
Objective,2,To screen the exogenous regulators that can induce resistance and stimulate Ginseng Radix et Rhizoma plants to produce secondary metabolites under artificial planting conditions.,Methods,2,Based on the inducible plant defense response, 2-year-old, 3-year-old and 4-year-old Ginseng Radix et Rhizoma plants were treated with exogenous substances such as salicylic acid, chitosan and amino acids. Ginseng Radix et Rhizoma plants were collected and the contents of ginsenosides Rg,1,, Re, Rb,1,, Rb,2,, Rb,3, and Rd in their main roots were determined by ultra high performance liquid chromatography with diode array detector (UPLC-PDA). The changes of fresh weight and ginsenoside content of single plant before and after treatment were observed.,Results,2,The growth/differentiation balance hypothesis (GDBH) was verified, suggesting that there is a contradiction between yield increase and high quality, and exogenous substances such as amino acids, salicylic acid and chitosan can induce plant defense response, start secondary metabolism and promote ginsenoside accumulation.,Conclusion,2,The compound nutrition of amino acids, salicylic acid and chitosan is the optimal exogenous regulator to effectively improve the fruit quality of cultivated Ginseng Radix et Rhizoma.
