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...

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...

This study compares the individual phenolic response of husk tissues Juglans regia L., infected to different degrees severity with walnut anthracnose, which is one most serious and widespread diseases worldwide. A comparison among three differently susceptible cultivars, ‘Franquette’, ‘Milotai 10’ (‘M10’), intenziv’ (‘M10-37’), made. In our methodology, high performance liquid chromatography co...

Leaf scorch, top dieback, and lethal bole cankers were found in two progeny tests of sycamore in Mississippi. Both tests indicated that southern seed sources are more disease resistant than northern seed sources and that some progenies within seed source have even greater resistance. Although eight organisms associated with one or more of the disease symptoms were identified, determination of t...
