STUDY ON THE DISTRIBUTION OF STRAINS OF PATHOGENIC FUNGI ON PINEAPPLES (ANANAS COMOSUS) IN SOME NORTHERN AREAS OF QUANG NAM PROVINCE

Abstract

  Pineapples (Ananas comosus) , the fruit of high economic value, occupy second place after bananas in terms of production. As for  area and total production, pineapples are classified as the country's principal group of fruits together with bananas and citrus trees. However, when the area under cultivation and production of pineapples are increased, diseases on pineapples  began to grow, mainly due to fungi. To study the distribution of strains of pathogenic fungi on pineapples is the initial material to find out the time of occurrence and duration of the most severe damage, supporting the work of planning, forecasting and highly effective control of diseases in production in order to reduce production costs and help  improve harvest yields, quality and commercial value of pineapples. In this study, we have found the law of distribution of strains of pathogenic fungi  in soil texture, seasons in different ecological zones of the Northern areas of Quang Nam province.
