The headblight or scab of wheat caused by Gibberella zeae (Schw.) Petch.has in recent years become more prevalent in the rice-wheat growing area ofEastern China with two heavy epidemics in 1952 and in 1954.It was reportedfrom this area that wheat varieties showed marked differences in their susceptibilityto headblight and that native varieties in general were less susceptible than theimproved ones.It was also reported that the degree of susceptibility appeared tobe related to the stage of host development.In 1952,varieties with earlier date ofheading were generally less susceptible than those which headed late. Varietal tests for the headblight resistance were made in Nanking in 1952and 1954.In 1952,235 varieties and hybrids were studied for their resistance toscab under natural conditions in the field.Great differences were found in theirdegree of infection,although none of them was immune.The percentages of in-fected heads ranged from 0.9 to 89.1 with most of them having 10 to 40% infec-tion.No definite correlation was seen between the percentage of infection andthe date of heading or of maturing.In 1954,tests on varietal resistance to scabwere again made with 40 varieties and hybrids including those being relatively lesssusceptible in the previous test.Attempts were made to induce epidemics in thefield by means of artificial inoculation.Results indicated that both mycelial andconidial suspensions were similarly effective for artificial inoculation.The averagepercentages of infected heads in the inoculated plots ranged from 4.2 to 77.7 incontrast to the uninoculated plots where the average percentages of infected headsbeing only trace to 7.1 with one variety not infected. From the experimental results obtained in 1952 and 1954,it was found thatrelative stability in resistance to headblight existed among different wheat varie-ties,although there was great variation in varietal resistance due to the effect ofenvironmental factors.Two hybrids,"5201" and "5204",were found to be muchmore resistant than all other varieties tested in both years.Hybrid "5204" gave ??0.9% of infected heads in 1952 and 3.4% in 1954,and hybrid "5201" gave5.5 and 9.0% of infected heads in the respective years.Both hybrids also possessother desirable characteristics such as early maturity,relative high yield,stiffystems,and high resistance to the stripe rust. Greenhouse studies were made in 1954 with two susceptible varieties ofwheat for testing their susceptibility to headblight at six different stages of deve-lopment from shooting to hard dough.Results indicated that the plant was sus-ceptible at all these stages of development with a tendency of being more heavilyinfected toward maturity.It was also observed that temperature had obvious effecton the degree of infection.Plants inoculated at flowering stage were more heavilyinfected when kept at 25℃ after inoculation than when kept at 15℃.However,the inoculated plants kept at 25℃ during the day and at 15℃ at night resultedin a degree of infection similar to those kept at 25℃ all the time.

(一)小麦赤微病在苏、浙、皖的稻麦两熟地区经常严重发生,1952及1954年两度猖獗流行,造成苏南及浙江地区小麦生产上的严重损失。通过调查,发现各地小麦品种对病害的反应确有显著差异。地方品种,一般发病较轻,而改良品种如“2905”、“2419”、“玉皮”、“矮立多”等,常常严重地感染病害。(二)1952年在自然情况下,观察此较235个小麦品种结果,虽没有一个品种不发病,但品种间的发病率相差极大,自0.9%至89.1%,而不同品种感染程度的轻重与抽穗期及成熟期的早迟关系不大。(三)1954年大田人工接种结果,效果显著,供试40个品种接种区的最高发病率达77.7%,而自然感染区的最高发病率只有7.1%。在接种试验中,初步证明:(1)大量有效的病原体与适合病害发生的气候因子同是病害流行的主要条件;(2)接种方法,用菌丝体接种与用分生孢子接种的效果,并无多大差别;(3)品种的抽穗先后,与发病轻重无一定关系。(四)温室试验指出,小麦自抽穗至糊熟各期麦穗被害率相似,但小穗的被害率在抽穗期最低,开花以后,有愈近成熟感染程度愈重的趋势。(五)开花期接种后的小麦,置於25℃的麦穗被害率和置於15℃的相似,但前者的小穗被害率此后...

Among collections chiefly from North China,different races of Pucciniaglumarum were identified by means of differential hosts used by Gassner & Straibor a set of improved varieties of wheat grown in China. Among 14 improved varieties,marked differences in resistance to stripe rustwere observed.Li-Yung I was resistant to 40 out of 50 collections of striperust,with unstable reactions to 7 collections; Nanking 4197 was resistant to 37 ??collections with unstable reactions to 9 collections; while Yechao 35368 and Ye-Ta 1885 were susceptible to all except 5 collections from FJymus ckinense.Theinstability of varietal reactions is one of the principal obstacles in identification.As a consequence,tests with 6 improved varieties including Early Premium,Pi-Ma 1,etc.,only 21 out of 50 stripe rust collections could be differentiated into10 distinctly different races (Y 1 to Y10).However,there were great differencesin pathogenicity among different races so far identified.All the 6 improvedvarieties were resistant to race Y 1 and susceptible to race Y 2.The virulenceof other races differed from one another also pronouncedly. Races Y2,Y3,Y4,Y5 ,Y6,Y7 ,and Y8 were collected from wheat; Y 9 andY10 from Agropyron spp.; and Y1 was collected mainly from Elymus chinense(including 1 collection from wheat).Races Y 1,Y 3.Y 4,Y 5,Y 7,Y 8,Y 9,Y 10were found in Hopeh; Y 1,Y 2,Y 6,Y 7 in Shansi; and Y 6 in Shantung. All collections could be readily grouped into 16 different forms if the highestreaction type was taken as a basis for identification (this method of groupingwas adopted by Fang et al).Comparing the results with that of Fang et al,itappeared that reactions of certain varieties,such as Early Premium,Li-Yung 1 tocollections from North China were distinctly different from their reactions tocollections from East China.This suggested strongly that races of stripe rustorganism between these two regions might be quite different. All wheat varieties tested were found to be resistant to stripe rust collectionsfrom Elymus chinense.whereas collections from Elymus sibiricus and Agropyronspp.were capable of attacking many wheat varieties. Single spore infection of stripe rust frequently resulted in sporulation on thewhole leaf blade.This is definitely much more systemic than infections of eitherstem rust or leaf rust organism.Inoculations with single uredospores and mono-uredospore lines often produced mixtures of infection types ranging from resistantto susceptible on same leaf blades.This is analogous to "X" type reactions re-ported in stem rust and leaf rust literature; therefore,"X" type reaction shouldalso be recognized in the study of stripe rust.

1950年以来自华北以及少数其他地区搜集的条銹菌种,不論在Gassner和Straib所用的鑒定寄主或在国內推广品种上鑒定,都可区分出許多不同的类型。所用14个推广品种对于这些条绣菌种的抗病性有着很大的差別;其中以驪英1号最抗病,对50个菌种中的40个菌种是抵抗的,对7个菌种反应不稳定;金大4197次之,对37个菌种是抵抗的,9个菌种反映不稳定;燕交35368及燕大1885除了对5个碱草(Elymus chin-ense)条銹菌种抵抗外,对其他所有菌种的反应都是感染型。品种反应的不稳定,是鑒定工作中的主要困难。加根据早洋麦、农大3号、碧螞1号、碧螞4号、驪英3号、玉皮麦等6个品种的稳定反应加以分析,仅能將50个菌种中的21个区分成10个显著不同的类型。这6个品种对第一类型均为抵抗,对第二类型均为感染,其他类型的致病力介于二者之間。在这10个类型中,类型Y_2,Y_3,Y_4,Y_5,Y_6,Y_7,Y_8采自小麦;类型Y_9,Y_(10)采自Agropyron spp.;类型Y_1主要采自Elymuschinense(包括一个小麦菌种)。河北出現的类型有Y_1,Y_3,Y_4,Y_5,Y_7,Y_8,Y_9,...

The acute and chronic toxicities of parathion, O,O-diethyl O-p-nitrophenyl thiophosphate, in the white mice (Mm rmtseulus albus Bechstein) were investigated by oral administrations. The dosage rate was based on the weight of the mouse; and the calculated volumes of the diluted parathion emulsion in various concentrations were fed to the test animals by means of a needle of the micrometer syringe. The various dosage rates for five groups of mice were as follows:(1) A single oral dose of 20 mg. of parathion per kg. of body weight;(2) A daily dose of 5 mg. of parathion per kg. of body weight;(3) A daily dose of 10 mg. of parathion per kg. of body weight;(4) The mouse recieved a dose of 1 mg. of parathion per kg. of body weight at the 1st day and thereafter the dosage was increased by 1 mg. per kg. of body weight with the increase of days;(5) The mouse recieved 2 mg. of parathion per kg. of body weight at the 1st day and the dosage was increased by 2 mg. per kg. with the increase of days.In the above various daily dosage rates for the different groups of mice, parathion was fed continuously over a period of 12 days except in cases when all the test animals under experiments were dead before that period of time. The experimental results may be summarized as follows.1. The symptoms of parathion poison in the white mice were observed at follows: inaction, slight tremor, followed by omitting, tears, diarrhea, and the intensive convulsion. Finally the mouse with its erected and stiffened tail ran about for a few seconds and died.2. Either in treatments of a single acute oral dose or of daily oral dosages of parathion in succesion, the poisoned mice showed no apparent differences in susceptibilities between males and females or among animals with various body weights.3. It was found that a single dase acute oral LD50 value within 24 hours was between 10 mg. and 20 mg. of parathion per kg. of body weight.4. The average period of time required from the last administrations to the dealh of the animals was about 2 hours in the treatment (1), (3), (4), and (5). The treatment (2) took about 7 hours. In all the treatments, the required time varied from only 16 minutes to 11 hours.5. In the treatment of daily dosage of 5 mg./kg. 6 mice died within 4 days after the beginning of the administration, 9 mice survived to the end of the 12 days, having taken a total dosage of 60 mg./kg.The treatment with a daily dosage of 10 mg./kg. showed that 11 out of the 15 tested mice died before the 3rd day. Of the remaining 4 mice, 2 died suddenly at the 7th day, while the other 2 survived to the end of the 12th day, having taken a total dosage of 120 mg./kg.In those cases, when the mice recieved a dose of 1 mg./kg. at the 1st day, and then dosage increased by 1 mg./kg. at the successive days, some of the mice (so treated) died at the 4th day and the death of the poisoned mice continued to happen till the end of the 12th day. Only 3 out of the 15 mice survived after haying taken a last dose of 12 mg./kg. and total dosage of 78 mg./kg.In those cases, when the mice recieved a dose of 2 mg./kg. at the 1st day and continuously recieved a dosage which increased by 2 mg/kg. at the successive days, all the 15 test mice died before the 8th day, after having taken a total dosage of 72 mg./kg.The results of the four above dosage treatments showed that the daily administration of parathion at sublethal dosages to the mice did not apparently have any accumulative action, while the daily dosages near the acute lethal level did cause some susceptible mice to die. This may be due to the possibility that the poisoned mice could not recover their cholineste-rase level enough to resist the inhibiting effects of the next applications of parathion.
