First Report on Fusarium Wilt of Zucchini Caused by Fusarium oxysporum, in Korea
Fusarium wilt of zucchini in Jeonju, Korea, was first noticed in May 2013. Symptoms included wilting of the foliage, drying and withering of older leaves, and stunting of plants. Infected plants eventually died during growth. Based on morphological characteristics and phylogenetic analyses of the molecular markers (internal transcribed spacer rDNA and translation elongation factor 1α), the fung...
متن کاملFirst report on Fusarium virguliforme in Persian Gulf Beach soils

Persian Gulf beaches in Iranare the ideal habitat for a variety of Fusarium species. Therefore, the study is conductedto gather some information on the population of Fusarium species which could be foundin Persian Gulf beaches in Iran. The study involv...
متن کاملCitrus Section Phloem Anatomy of Citrus Trees: Healthy vs. Greening-affected
Phloem cells from HLB-affected trees become obstructed with callose and P-protein plugs. The presence of these plugs is believed to hinder the translocation of photoassimilates (nitrogenous and reduced carbon compounds) to the root system. However, even with seemingly collapsed phloem tissue, citrus trees remain viable and produce fruit for some time, suggesting either incomplete plugging of ph...
متن کاملMorphological and molecular characterization of Fusarium spp. associated with olive trees dieback in Tunisia
Dieback and wilting symptoms caused by complex soilborne fungi are nowadays the most serious threatening disease affecting olive trees (Olea europaea) in Tunisia and presumably in many Mediterranean basin countries. Fusarium is one of the important phytopathogenic genera associated with dieback symptoms of olive trees. The objective of the present study was to confirm the pathogenicity of Fusar...
متن کاملGrowth of Citrus Trees as Affected by Ethylene Evolved from Organic Materials Applied to Soil'
This study was carried out to examine the effect of ethylene, which is evolved from organic materials applied to soil, on the growth of citrus trees. The roots were exposed to 0, 0. 05, 0. 5, 5, and 50 ppm ethylene in the soil atmosphere for 4 weeks. Shoot elongation, total and root fresh weights, main root length, and succinate dehydrogenase activity of roots, were severely inhibited at and ab...
