通过试验,作者提出了适用于预测毒病的标准诱蚜法的建议:1.黄皿颜色朵用金盏黄;2.黄皿边缘做一条(宽约5厘米的)黑边;3.皿的面积为900平方厘米,深3厘米;4.黄皿设在离地0.5米的高度。为了防止下雨溢水,皿边上缘开一小孔(直径约1厘米),孔上蒙一层铜炒。对别的诱蚜方法也进行了简单的评述。

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。

This is a discussion of the natural phenomena and the reported experimental data ofcitrus yellow shoot disease in China which come to the writer's notice.The disease,allied with tristeza virus disease,has long been known.However,in thenorthern citrus growing regions and at high elavations in the southern part,it is entirely ab-sent or only rarely occurs.Shading provided by topography,such as hills of a valley,andother trees,such as wind break and interplanted deciduous fruit trees,is also unfavorablefor its outbreak in individual orchards,despite of plenty of severely diseased ones in the sur-roundings.There are several possible explanations for the correlation of macro-and micro-climates with the incidence of the disease.But it is considered important to find out firstwhether the influences are exerted on the vector of the virus or on the post-infectional host-virus relationship.The scions taken from diseased shoots develop into apparently normal shoots which remainhealthy for a considerable length of time.Yellow shoots most frequently make their firstappearance on young trees following a year of over-loading of fruits.There is one case ofsuccessful permanent cure of the young tree at its early stage of disease by simultaneousheavy pruning and side-grafting.These phenomena may be explained on the basis of therelation of top/root ratio to pathogenesis of the virus disease.Apparently,there are specific and varietal differences in tolerance of citrus trees to thevirus infection.Similar differences may also exist among clones and individuals within thesame variety,because scions taken from old healthy-looking trees in diseased area give lowerpercentage of diseased plants than those taken from young trees.Variations in transmission and occurrence of the disease may also be due to the differencein virulence of the virus strains which interfere with each other and the fluctuations or un-eveness of concentration of the virus within its host.The writer hereby expresses the beleif that further researches might lead to the applica-tion of cultural,varietal and vaccinal immunization against the hazard of citrus yellow shootdisease.

柑桔黄龙病在我国北部产区及南部高山发生得很轻微或完全不发生。在南部的重病区中,由于地势、防风林、间作果树等所造成的遮蔭条件也不利于病害的发生。大气候和小气候与黄龙病的相关有多种可能的原因。但首先应当研究它们对病毒传播媒介和侵染后发病的影响。用病芽作为接穗所长出的新梢在相当长时间内没有病状。最容易发病的是着果很多的幼树。初期发病的柑桔树通过重修剪和靠接辅助砧木的方法治疗有成功的实例。这些现象都可以从树冠树根比例与发病的关系来解释。柑桔类的种和品种间显然存在着耐病力的差异。这种差异也可能存在于同一品种的不同株系和个体间,因为用病区老树的接穗比幼树的接穗育成的苗木发病率较低。在黄龙病传播和流行上的许多不一致的现象还可能决定于病毒浓度和株系间毒力的差异及其相互关系。上述问题的研究可能导致栽培免疫、品种免疫和人工接种免疫方法的应用。
