Abstract

Squash (Cucurbita pepo) belongs to Cucurbitaceae family. Every year Cucurbitaceae are planted world wide. They are one of the most important economic crops. Cucurbitaceae are threatened by viruses. Many viruses damage the plants of this family. Since nine viruses have been reported on squash from Iran. In this survey, during 2002--2003, to determine the distribution of Cucumber mosaic virus (CMV), Zucchini yellow mosaic virus (ZYMV) and Watermelon mosaic virus (WMV), 466 samples were collected from squash field in Tehran province. Infected plants showing symptoms such as: mosaic, yellowing, deformation, shoestring of leaves and fruit deformation and yield reduction. Distribution of CMV, ZYMV and WMV were determined by DAS-ELISA. Thepercentage of ZYMV, WMV and CMV were 35.6, 26.1 and 25.1% respectively. Triple infection (CMV+ZYMV+WMV) were found in 6.4% of samples. ZYMV were found the most frequently the viruses. This is the first report of WMV on squash in Tehran province.

摘要

西葫芦（南瓜属）属于葫芦科。每年葫芦科作物都在全球范围内种植。它们是最重要的经济作物之一。葫芦科作物受到病毒的威胁。许多病毒会损害该科的植物。自伊朗已报道有九种病毒感染西葫芦。在本次调查中，于2002年至2003年期间，为确定黄瓜花叶病毒（CMV）、小西葫芦黄花叶病毒（ZYMV）和西瓜花叶病毒（WMV）的分布情况，从德黑兰省的西葫芦田采集了466个样本。受感染的植株表现出诸如：花叶、黄化、变形、叶片呈鞋带状以及果实变形和产量降低等症状。通过双抗夹心酶联免疫吸附测定（DAS - ELISA）来确定CMV、ZYMV和WMV的分布。ZYMV、WMV和CMV的感染率分别为35.6%、26.1%和25.1%。在6.4%的样本中发现了三重感染（CMV + ZYMV + WMV）。ZYMV是最常发现的病毒。这是德黑兰省关于西葫芦感染WMV的首次报道。
