گزارش قارچ Cryphonectria parasitica عامل بلایت درختان شاه بلوط (Castanea sativa) از ایران
جنگلهای شاه بلوط ایران تنها به مناطق خاصی از استان گیلان نظیر مناطق کوهستانی شهرستان شفت (ویس رود، طالقان و لپوندان)، تالش (شفارود و آق اولر) و فومن (قلعه رودخان) محدود بوده و همین رویشگاه محدود نیز در معرض خطر نابودی قرار گرفته است. بنابراین صیانت از آن از اهمیت ویژه ای برخوردار است. در این تحقیق، طی بازدیدهایی که از رویشگاه درختان آلوده و بیمار شاه بلوط در جنگلهای ویس رود و شفارود انجام پذیرف...
متن کاملCharacterization of Chestnut (Castanea sativa, Mill) Starch for Industrial Utilization
Studies were conducted to characterize the chestnut and its starch. Chemical composition of the chestnuts showed high level of starch. Moisture level in the raw nuts was around 50g/100g in wet basis and starch content, around 80g/100g in dry basis; other nut flour components were protein (5.58 g/100g), lipid (5.39 g/100g), crude fiber (2.34 g/100g) and ash (2.14 g/100g). Starch fraction was che...
متن کاملNutritional quality of chestnut (Castanea sativa Mill.) cultivars from Portugal
Chemical composition of eight sweet chestnut cultivars from the three protected designation of origin (PDO) areas in the Trás-osMontes region were studied: Aveleira, Rebordã, Trigueira and Zeive from PDO ‘Terra Fria’, Demanda, Longal and Martaı́nha from PDO ‘Soutos da Lapa’ and Judia from PDO ‘Padrela’. Chestnuts were characterised by high moisture content ( 50%), high levels of starch (43 g 100...
متن کاملCharacteristics of Hypovirulent Strains of Chestnut Blight Fungus, Cryphonectria parasitica, Isolated in Korea
Chestnut blight disease caused by Cryphonectria parasitica is widely distributed throughout chestnut tree plantations in Korea. We surveyed 65 sites located at 9 provinces in South Korea, and isolated 248 virulent and 3 hypovirulent strains of chestnut blight fungus. Hypovirulent strains had dsRNA virus in the cytoplasm, which is one of the typical characteristics of hypovirulent strains. In ad...
متن کاملGenetic control of horizontal virus transmission in the chestnut blight fungus, Cryphonectria parasitica.
Vegetative incompatibility in fungi has long been known to reduce the transmission of viruses between individuals, but the barrier to transmission is incomplete. In replicated laboratory assays, we showed conclusively that the transmission of viruses between individuals of the chestnut blight fungus Cryphonectria parasitica is controlled primarily by vegetative incompatibility (vic) genes. By r...
