Abstract:
Taking Paeonia lactiflora as test material,Serendipita indica was inoculated into P.lactiflora by soaking and watering.And the P.lactiflora was refrigerated to forcing cultivation.The effects of S.indica on P.lactiflora root system,biomass,plant height,stem length,stem diameter,flower bud number,chlorophyll content,plant phosphorus content and rhizosphere soil phosphorus content were analyzed,in order to provide reference for further study of the effect of S.indica on the growth and phosphorus uptake and utilization of host plants.The results showed that S.indica could infect the new capillary roots of P.lactiflora,but did not colonize the perennial rhizomes and root tubers.The fresh weight of the capillary root was increased by 14.14%,53.05% and 39.62% ,in the germination stage,leaf flushing stage and squaring stage respectively.In leaf flushing stage and budding stage,the fresh weight of shoot increased by 57.31% and 49.46%,respectively,total chlorophyll content increased by 17.68% and 34.15%,respectively,stem length and bud number increased by 22.84%% and 183.33%%,respectively.In the leaf flushing and squaring stages,the phosphorus content in the shoots of P.lactiflora increased by 30.08% and 40.61%,respectively.Compared with the budding stage,in the squaring stage the total phosphorus content in the soil decreased by 9.38% and the available phosphorus content decreased by 31.49%.S.indica can stimulate the growth of capillary roots,enhance the photosynthetic rate,increase P.lactiflora′s absorption of available phosphorus,improve the phosphorus content in P.lactiflora shoots and promote the growth of Peony by infecting the newly born capillary roots of P.lactiflora.
