Market Disease Pathogens Detection of Imported Fruits in Shanghai
Market Disease Pathogens Detection of Imported Fruits in Shanghai
摘要
Abstract
A tremendous amount of imported fresh fruits has been delivered to Shanghai markets,increasing the risk of invasion by harmful plant pathogens.Therefore,it is important to establish an effective detection and supervision system to survey the outbreak of the market diseases of the imported fruits during marketing.The samples were regularly surveyed in different markets to examine varieties,prices,localities,selling conditions,and diseases of the imported fruits from 2004 to 2008.The survey showed that 58 species of 30 different fruits were imported to Shanghai from 16 countries with more expensive price.The larger products were bananas,grapes,apples,and oranges.During the investigation,we found that the imported fruits frequently brought about the relatively serious market diseases.On the basis of morphology and the nuclear internal transcribed spacer (ITS) of ribosomal DNA (rDNA) analysis,151 isolates of 15 fungi genera,which shown to be pathogenic afcer the inoculation assay.were finally identified.Among the identified fungi,Alternaria was the most frequent one with the highest detection rate (47.68%),followed by Penicillium (14.57%) and Fusarium (11.92%),respectively.Additionally,Pestalotiopsis microspora (detected in grapes Red-Globe coming from the USA) and Botrytis sp.(detected in black-plums coming from the USA)were first reported in China market.The present study summarized the selling situation of the imported fruits in Shanghai markets and constructed a library of the pathogens detected in the imported fruits during the selling period.The results obtained are useful to offer technical parameters for Chinese quarantine in order to prevent an invasion of the foreign harmful micro-organisms.关键词
