During 1957 and 1958,a survey of the virus diseases of cucurbit crops was carried out inPeking.Not only the symptoms of the naturally infected plants were described,but also thesamples of the diseased plants were collected and proceeded to routine diagnosis.The mosaicdisease of vegetable marrow(Cucurbita pepo L.var.)was very severe in this district.Theessential causal factor of this malady was revealed to be the Muskmelon Virus(=Marmormelonis Raeder et al.)which evidently caused the systemic infection of watermelonand hada lower thermal death point(55-62℃).In the case of the mosaic disease of squash(Cucurbitamoschata var.melonaeformis,Makino),a similar virus was isolated,however,it differed fromthe above strain by not attacking watermelon,although having the same thermal resistance.From the specimens of the mosaic disease of cucumber plants,all isolates were pertain-ing to the Cucumber Mosaic Virus(CMV=Marmot cucumeris Holmes)group,consisting oftwo or more distinct strains,except a peculiar entity was isolated from a specimen of theautumnal cucumber plant.This entity,having a higher thermal death point(85℃),did notattack Nicotiana glutinosa L.,but did systemically infect N.tabacuum L.and N.sylvestris L.and caused local necrotic spots on Datura stramonium L.It was tentatively considered as anew strain and named Autumnal Cucumber Mosaic Virus(ACMV).All isolates from variousmelons were demonstrated to be the same entity as that obtained from the vegetable marrow,namely the Muskmelon Virus(MMV).A virus isolated from Luffa cylindrica Roem.was shown to have distinct properties butclose to MMV.Owing to its rather restricted host range among cucurbits,it was possibly adistinct strain of the Muskmelon Virus. 从1957到1958年,在北京都区进行了瓜类作物花叶病毒的调查研究。在记述病作物症状的同时,还采集了各类花叶病株的标样,进行了病毒的常规鉴定。西葫芦的花叶病是一个严重的病毒病,鉴定的结果证明其毒原主要为典型的甜瓜花叶病毒(MMV),而且能侵染西瓜而产生系统性花叶症。在南瓜的花叶病标样中分离到的也是甜瓜花叶病毒,但是这个株系不同于典型的甜瓜花叶病毒,因为它们都不侵染西瓜。从黄瓜花叶病标样中分离出来的病毒全属于黄瓜花叶病毒种羣(GMV),其中可能有不同的株系,而秋黄瓜上却分离出了一个毒原,不侵染心叶菸,系统侵染普通菸和毛叶菸,在蔓陀蘿叶上产生局部枯斑而具有较高的致死温度(85℃)。作者认为这可能是一个新单元,称之为秋黄瓜花叶病毒(ACMV)。所有在甜瓜,哈密瓜及绞瓜上分离出来的毒原都是属于典型甜瓜花叶病毒的,但梢瓜(即白瓜)上的毒原都是黄瓜花叶病毒(CMV),没有广州报告的白瓜花叶花病毒。丝瓜花叶病的分离物类似甜瓜花叶病毒,但寄主范围远较狭隘,很可能是一个甜瓜花叶病毒的新株系。 An isolate of MMV from Cucurbita moschata,infecting watermelon,became non-infectiousto Cucurbita maxima after passage through Luffa cylindrica.CMV is pretty common on various cultivated and wild plants in the vicinity of Peking.Eight strains are differentiated from the reactions on Benincasa hispida,Cucurbita moschata,Cucurbita maxima,Datura stramonium,Nicotiana glutinosa,and N.tabacum. 北京郊区南瓜、西葫芦花叶病是由甜瓜花叶病毒类型所致。黄瓜、参瓜、丝瓜的花叶病都是由黄瓜花叶病毒类型所引起;黄瓜花叶病毒除为害瓜类作物外,还广泛分布在郊区其他栽培作物和野生植物上。根据 CMV 各分离物在冬瓜、南瓜、蔓陀罗,心叶菸,菸上的病状反应,建议将 CMV 分离物区分为八个毒株。来自南瓜并侵染西瓜的一个甜瓜花叶病毒分离物在侵染丝瓜后不能用汁接侵染荀瓜。 The watermelon mosaic virus-WMV-2 (BJ),inducing a mosaic di- 根据作者研究西瓜花叶病毒除侵染葫芦科作物外,还在苋色藜上形成枯斑,桃蚜可作为传毒媒介。病毒的长度为600～700mμ的线状分子等特性,引起北京西葫芦花叶的病毒应属于西瓜花叶病毒——WMV-2。

The study also showed that intercropping with watermelon and vegetables proved to have the highest economic return among the treatments adopted.
The rheological properties of ethylene-vinyl acetate copolymers of various compositions in blends with pectins of various origins (pectins recovered from apple pulp, watermelon peel, and citrus fruits) were studied.
Using carboxyfluorescein, a fluorochrome transported along the phloem, we demonstrated that symplasmic phloem unloading in the watermelon root occurred in the basal zone of the meristem adjusting to the elongation zone.
