Abstract

This research was conducted at the Department of Plant Pathology, University of Agriculture Peshawar during the 2011 growing season of the crop to determine the response of various cultivars of cucumber to different isolates of the downy mildew fungus Pseudoperonspora cubensis under artificial epiphytotic conditions. Five cucumber cultivars (Desi, Long Green, F1 hybrid, Dollar and Khyber) were tested for their response to infection by four different isolates of Pseudoperonospora cubensis. Significant differences (p<0.05) were found among the treated and control plants. F1 Hybrid and Dollar F1 were found to have the least disease severity. Among the isolates, isolate 4 caused the highest disease severity. In control plants, the disease severity was less. The interaction of cultivars and isolates was also significant in disease severity after thirty and forty days of inoculation.

不同黄瓜品种对不同菌株的黄瓜假operonospora cubensis的反应(Berk et Curt.)罗斯托在人工附生条件下

本研究于2011年作物生长季节在白沙瓦农业大学植物病理学系进行，以确定不同品种的黄瓜在人工外植条件下对不同菌株的霜霉真菌cubensis假operonspora的反应。以5个黄瓜品种(德西、长绿、F1杂交、多勒和开伯尔)为试验材料，研究了4株不同菌株对黄瓜假operonospora cubensis的侵染反应。处理株与对照株间差异显著(p<0.05)。杂交F1和Dollar F1的疾病严重程度最低。其中，分离物4引起的疾病严重程度最高。对照植株的病害严重程度较轻。接种30d和40d后，品种和分离株的互作对病害严重程度也有显著影响。

期刊介绍： Journal of Soil, Plant and Environment is an open peer-reviewed journal that considers articles and review articles on all aspects of agricultural sciences. Aim and Scope Journal of Soil, Plant and Environment (ISSN: 2957-9082) is an international journal dedicated to the advancements in agriculture throughout the world. The goal of this journal is to provide a platform for scientists, students, academics and engineers all over the world to promote, share, and discuss various new issues and developments in different areas of agricultural sciences. All manuscripts must be prepared in English and are subject to a rigorous and fair peer-review process. Accepted papers will appear online within 3 weeks followed by printed hard copy. Journal of Soil, Plant and Environment (ISSN: 2957-9082) publishes original papers including but not limited to the following fields: Soil–plant relationships; crop science; soil science; biometry; crop, soil, pasture, and range management; crop, forage, and pasture production and utilization; turfgrass; agroclimatology; agronomic models; integrated pest management; integrated agricultural systems; and various aspects of entomology, weed science, animal science, plant pathology, and agricultural economics as applied to production agriculture. We are also interested in: 1) Short Reports– 2-5 pages where the paper is intended to present either an original idea with theoretical treatment or preliminary data and results; 2) Book Reviews – Comments and critiques of recently published books in agricultural sciences.
