Although self incompatibility in walnut has not been reported, but the dicogamy limits self pollination of walnut cultivars. As the density of female flowers produced by the tree is low, if a high fruit set occurs, yield especially in terminal bearing cultivars will not be high. So breeding of a pollinizer cultivar with proper pollen shading period is highly necessary for increasing fruit produ...
most of walnut production in iran comes from seed originated trees with low quality and quantity as product. for breeding new cultivar(s), from 1983 selection of iranian walnut germplasm was started at seed and plant improvement institute and at the first phase 117 genotypes were collected. seedlings of these genotypes were planted in kamalshahr (karaj), torogh, kahriz and bastam horticultural ...

آنتراکنوز گردو شایعترین بیماری قارچی گردو در ایران بوده و در سالهای پرباران و خنک، خسارت زیادی به این محصول وارد میکند. این مطالعه به منظور سبب شناسی و تعیین پراکندگی بیماری در ناحیه شمال غرب کشور به عنوان یکی از قطبهای عمده تولید گردو انجام گردید. در این تحقیق تعداد 75 جدایه از گردوکاریهای 11 استان ناحیه شمالغرب کشور جداسازی گردید. پریتسیومها از برگهای ریخته شده استحصال و یا تولید آن...
Diversity and species composition of endophytic fungi on leaves of 11 tree 10 species in Betulaceae were studied, with reference to climatic, tree species, and seasonal 11 variations. A total of 186 fungal isolates were obtained from 190 leaves collected in a 12 subalpine, a cool temperate, and a subtropical forest in Japan and were divided into 46 13 operational taxonomic units (OTUs) accordin...
