| 1 | Pre-harvest and post-harvest application of benzothiadiazole for controlling anthracnose and extending shelf life of harvested banana显示文摘Anthracnose,caused by the fungus Colletotrichum musae,is a serious latent post-harvest disease of banana,which results in major economic losses during transportation and storage.Benzo-thiadiazole-7-carbothioic acid S-methyl ester(BTH),a functional analogue of the plant endogenous hormone-like compound salicylic acid(SA),has been known to possess resistant effects on some diseases caused by fungi.The aim of present study was to select an appropriate BTH concentration and an appropriate stage of banana ripening for its application in controlling anthracnose and extending shelf life of harvested banana fruit.Different concentrations of BTH(50,100,200 and 300μg/mL)were applied at different stages of banana fruit ripening,including one week,two weeks and one month before harvest.The results suggest that while the concentrations of BTH ranging from 50μg/mL to 200μg/mL in both pre-harvest and post-harvest application,this could control anthracnose of harvested banana fruit,the appropriate concentration of BTH in both pre-harvest and post-harvest treatment was 100μg/mL and the best time of BTH treatment was two weeks before harvest.Examination of quality parameters including peel color and firmness indicated that 100μg/mL BTH treatment delayed banana fruit ripening at room temperature. | Li Xueping Shi Jingying Zhu Xiaoyang Wang Jinghua Yuan Zhenxin Luo Jun Liu Tongxin Wang Rong Rao Shen Chen Weixin | 2013 | International Journal of Agricultural and Biological Engineering2013，6，4： | 0 |
| 3 | Public policies and conservation plans of historic urban landscapes under the sustainable heritage tourism milieu: discussions on the equilibrium model on Kulangsu Island, UNESCO World Heritage site显示文摘Purpose The tensions and threats in historic urban landscapes brought about by heritage tourism are still regional,global,general,and dynamic issues.For Kulangsu,there is an obvious problem in the connection between the current conservation plan and public policy.To a large extent,public policy cannot effectively,specifically,and flexibly respond to the dynamic problems in the implementation of the conservation plan,which seems insufficient concerning the effect of these conservation plans and public policies on promoting the adaptive reuse and sustainable tourism of the historic urban in Kulangsu heritage sites.Thus,giving more consideration to the combination of public policies and conservation plans of historic urban landscapes under the heritage tourism milieu,ensuring a balanced,sustainable,and integrated development pattern still calls for new discussions in achieving good performance of sustainable heritage tourism.This study conceptually discusses the equilibrium model of historic urban landscapes with a range of strategies under a sustainable heritage tourism background and responds to the synthetic contradiction of the imbalances among public policy,conservation plans,and development practices.Design/methodology/approach The study is based on a range of prepared desktop studies(public policy studies,conservation plans),field surveys,participant observations,and randomised interviews to respond to the insufficiency of the current heritagepractices.Findings This study discusses the equilibrium model of sustainable heritage tourism at heritage sites.It takes Kulangsu Island,a UNESCO World Heritage site in Southeast China,as an example to discuss the equilibrium model,which encompasses a convergent parallel framework and three dimensions concerning heritage management and policymaking.The equilibrium model of historic urban landscapes is a dynamic framework that integrates social,economic,environmental,and cultural concerns into a holistic collaborative framework under a sustainable heritage tourism background.Originality/value In line with the requirements of the Historic Urban Landscape(HUL)approach and general principles in support of sustainable urban heritage management promoted by UNESCO and ICOMOS,the study points out the peculiarities and potential of the equilibrium mode in solving the current challenges of historic urban landscapes for sustainable heritage tourism.Finding ways of linking policymaking,conservation,development,heritage tourism,and different interest groups to a holistic framework can stimulate effective means and management mechanisms for the complicated and changeable issues of sustainable heritage tourism. | Long Zhao Yuan Li Na Zhang Zhenxin Zhang | 2023 | Built Heritage2023，7，1： | 0 |
