Various factors affect the development of headblight of wheat caused by Gibbe-rella zeae (Schw.) Petch under field conditions.The present investigation carriedout in 1955 and 1956 at Nanking,Kiangsu province,was primarily concerned withthe development of spores of the pathogen and the amount of rainfall in relationto disease development.For the purpose of inducing epiphytoties of the disease,asusceptible variety of wheat to headblight was grown in the inoculated plots.Inoculation was made at the surface of the soil with mycelium cultured on wheatgrain shortly after planting,and an "artificial rain" by frequent spray of water tothe plants was supplied after heading.Investigations were made on the develop-ment and dissemination of ascospores and conidia of the pathogen,the seasonaldevelopment of the disease and the meteorological factors involved. Field observations showed that the headblight fungus on the soil surface inthe inoculated plots produced both kinds of spores with ths ascospores much morepredominant than the conidia.Perithecia and mature ascospores could be formedboth in the fall and in next spring through early summer under conditions ofadequate moisture and warm temperature suitable for their development.It wasindicated by trapping the spores in the air that the ascospores produced on thesoil surface were the chief source of inoculum for primary infection although theconidia formed on the infected spikes were equally important in spreading the di-sease in the field later in the season.The frequency and amount of ascosporesand conidia present in the air depended upon the height in spore trapping.Whilespores were found most frequently and most abundantly at a height of 17 cm.above the ground,much less spores were caught at heights of 33 cm.and up to117 cm.There was a tendency to decrease in the amount of spores with theincrease in height.A comparative survey of the spores in the air in the inoculated ??and uninoculated plots indicated that a great majority of spores could not bedisseminated very far from their source of production.This,together with thefact that comparatively more spoies were trapped on raining days,made it rea-sonable to consider splashing rain as the more important agent than wind forspore dissemination. The amount of inoculum existing in the soil and the rainfall were proved tobe the factors of utmost importance for the epiphytotic of the disease.In 1955,the average percentages of headblight for the inoculated plots with and withoutthe spray of water were 29.4 and 13.4% respectively,in comparison with the neigh-bouring fields where only very few infected heads were observed.In 1956,theaverage percentages for headblight in the four experimental plots:(1) inoculatedand sprayed with water,(2) inoculated and not sprayed,(3) uninoculated andsprayed,and (4) uninoculated and not sprayed,were 42.98,42.05,11.91 and6.26%,respectively.In these four corresponding plots,the average percentagesfor culm rot were 4.27,3.89,3.65 and 2.17%.Although there was no significantdifference in the final percentages of both headblight and culm rot between thesprayed and unsprayed plots either with or without inoculation,probably due tothe continuous heavy rain in the latter part of the wheat-growing season,yethigher percentages were always observed in the sprayed plots than in the un-sprayed ones throughout the period of disease development.Under conditions ofabundant inoculum in the soil and heavy rainfall,increase in percentage of head-blight could reach as much as 32% within a period of two days even when theplants were already near maturity.In 1955,a daily average temperature over20℃ was found to be favorable for the development of headblight,but observa-tions made in 1956 did not show significant effect of the temperature on thedevelopment of disease.

1.黄麻根腐病为黄麻新的问题,目前了解的主要分布地区为浙江省沿钱塘江两岸的肖山、杭州市郊、原杭县等麻区。1954—1957年各地黄麻圆果种的平均发病率在14.7—24.6%以上。2.本病为害黄麻根及莖基等部分,使形成褐腐。病部不收缩,或微现收缩。后期病菌侵入输导组织,木质部形成黄褐色。8月下旬后,在病部出现大小约0.63×0.36毫米扁平不整形的黑色菌核,为本病的重要标志。3.本病以为害黄麻成株期为主。从6月下旬开始渐次出现病株,高峯期为8月下旬至9月下旬。在沙壤土中,地温(5厘米)平均在28—30℃,每旬降雨量在70毫米左右可以诱致严重发病。在一定温度下,雨量多少关系于发病程度极重要。4.经接种证实,本病为真菌Papulospora sp.所致,在病组织及普通培养基上不见分生孢子。生长发育以25—30℃为最适。矿物营养在缺碳时生长最差,缺氮时生长无大影响,迅速形成大量菌核;如加入蛋白腖,菌丝不复变色(白色),菌核不能形成。钾及磷对病菌生长发育的影响仅次于碳。5.含粘粒在10%以下的轻松土壤为最有利的发病环境。连作或轮作,对发病关系极为明显,多年连作地发病率较多年轮作或2—4年轮作地高7—53倍。...

禾谷类穗腐病系指由穗螨传播的真菌性白穗病。穗螨和真菌之间为专一性的共生关系。螨传播病原菌并刺激菌株生长;菌为螨的食物,并为螨提供适宜的生境。穗螨和真菌这种相互依赖的共生关系又受寄主植物、温度、湿度等条件影响。本文是穗螨与病原真菌共生关系的实验研究结果。
