Abstract
You should leave 8 mm of space above the abstract and 10 mm after the abstract. The heading Abstract should be typed in bold 9-point Times. The body of the abstract should be typed in normal 9-point Arial in a single paragraph, immediately following the heading. The text should be set to 1 line spacing. The abstract should be centred across the page, indented 17 mm from the left and right page margins and justified. It should not normally exceed 200 words. In order to explore the effects of fungus infestation on areca taro during cold storage period, a black morphologic fungus (No. 8) was isolated and identified as Curvularia lunata by morphological observation and 18sRNA gene sequencing. The study on its biological properties showed that the growth and development temperature of Curvularia lunata were 15-40 ℃, the optimal temperature was 25-30 ℃, the optimal pH was 6-8, the optimal light condition was natural light, the optimal carbon source was sorbitol, maltodextrin and mannitol, and the optimal nitrogen source was glycine. The optimum germination temperature, pH and humidity of conidia were 25 - 40℃, 6 - 9 and 100% + water drop, respectively, under the promotion of 40% areca taro solution. The aim of this study was to provide a theoretical basis for the prevention and treatment of areca taro rotting in cold storage period.
Highlights
Areca taro, known as lipu taro, fuding taro and fragrant taro, is a high starch aquatic vegetable belonging to araceae taro[1].After removing the rough skin, the stem block is milky white with brown or purple areca grain
Chen Xue-rong and others[4] found in the control of taro anthracnose and blight caused by seed dressing with bactericide that 300 times liquid dressing with 58% metalaxyl manganese zinc wettable powder had a better disease prevention effect and could effectively improve the commerciality and yield of taro
The strain was identified as Curvularia lunata
Summary
Known as lipu taro, fuding taro and fragrant taro, is a high starch aquatic vegetable belonging to araceae taro[1].After removing the rough skin, the stem block is milky white with brown or purple areca grain. The diseases and the species and quantity of spoilage bacteria during the growth of areca taro directly affect the storage effect after harvest. He Yan and others [2] systematically investigated the occurrence characteristics and rules of taro diseases and insects in Hezhou, Guangxi and found that taro was seriously harmed by taro blight, taro soft rot, taro blotch, spodoptera litura, taro aphid and underground pests during planting. Liu Qiong-ying and others [5] found in the efficacy test on the control of taro blight that 68% Redomir manganese zinc water dispersible granule, 72% metalaxyl manganese and
