The results showed that the diameter of Chaetomium cochliodes and Marssonina ro-sae increased with the culture time, and the diameter of them had significant difference at different culture time (P < 0.01) when they were cultured separately. When they were trained in confrontation, the colony diameter of Chaetomium cochliodes increased with time and had a significant difference at different culture time (P < 0.01), but there was no significant difference of Marssonina rosae . And the inhibitory rate of Chaetomium cochliodes to Marssonina rosae was up to 60.7% and the relative inhibitory rate was 5.38 after 72 hours, which indicated that Chaetomium cochliodes had significant inhibitory effect on Marssonina rosae , it can be used as a potential bio-control agent to control rose black spot.

In order to compare and evaluate the effects of different tree species on soil C storage and its stability, this paper took four typical plantations in the Huatan National Forestry Farm in Yangjiang City, Guangdong Province as research objects, and collected soil at a depth of 1 m to determine the total organic C (TOC) and easily oxidized organic C (ROC) contents and storage, to evaluate the soil C stability of the four stands by the ratios of ROC to TOC. The results showed that the TOC storage of the four stands were Pinus caribaea > Acacia mangium > Eucalyptus urophylla > Magnolia sumatrana , the soil ROC storage were Magnolia sumatrana > Pinus caribaea > Acacia mangium > Eucalyptus urophylla , and the ROC/TOC ratios were Magnolia sumatrana > Pinus caribaea > Acacia mangium > Eucalyptus urophylla . This indicated that the soil C stability of the four stands was the highest in Eucalyptus urophylla plantation and the lowest in Magnolia sumatrana plantation. The results of this study can provide scientific data reference for evaluating soil C sequestration and its stability in different plantations in western Guangdong.","PeriodicalId":71691,"journal":{"name":"林业世界","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136203536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
