变形菌门复合菌剂与厚壁菌门复合菌剂叶面喷施对当归生理代谢、产量及抗根腐病的影响
Effects of foliar spraying of Proteobacteria compound bacterial inoculant and Firmicutes compound bacterial inoculant on physiological metabolism,yield and root rot resistance of Angelica sinensis
摘要
Abstract
In this study,three treatments were set,including the Proteobacteria compound bacterial agent(BL),the Firmicutes compound bacterial agent(HH),and the potato dextrose broth(PDB)medium control(CK).After foliar spraying,the photosynthetic character-istics,antioxidant enzyme activities,nitrogen metabolism,hormone levels,yield and medicinal components of Angelica sinensis plants were determined to systematically evaluate the application effects of the two compound bacterial agents.The results showed that the net photosynthetic rate and photosyn-thetic nitrogen use efficiency of Angelica sinensis under BL and HH treatments were significantly higher than those of the control(P<0.05).In terms of the antioxidant system,the 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS)and 1,1-diphenyl-2-picrylhydrazyl(DPPH)radical scavenging capacities,peroxidase activity and total phenol content of Angelica sinensis under BL treatment were significantly higher than those of the control(P<0.05).The malondialdehyde content of Angelica sinensis under BL treatment was significantly lower than that of the control(P<0.05).The accumulation of jasmonates and cytokinins in Angelica sinensis was higher under BL treatment,while the accumulation of auxins and sali-cylic acids was higher under HH treatment.The contents of ferulic acid,coniferyl ferulate and Z-ligustilide in Angelica sinensis under BL and HH treatments were significantly higher than those of the control(P<0.05).The number of adventi-tious roots,rhizome diameter,main root length and dry weight per plant of Angelica sinensis under BL and HH treatments were significantly higher than those of the control(P<0.05).The root rot incidence of Angelica sinensis under BL and HH treatments was significantly lower than that of the control(P<0.05).Both bacterial agent treatments could promote the growth and development of Angelica sinensis plants,effectively enhance the disease resistance of Angelica sinensis,and achieve favorable effects of growth promotion and quality improvement.关键词
