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.

利用北极狐、黑白色长毛狐和水豹所做的实验表明溴水化氯醛具有明显的麻醉作用。麻醉效力没有水化氯醛强(小1.5—2倍),但毒性却比水化氯醛低。北极狐每公斤体重静脉注射溴水化氯醛0.5克可引起麻醉10—20分钟;水化氯醛,每公斤体重注射0.3克可引起麻醉20—30分钟,但在每公斤体重注射水化氯醛0.3克后已发现有动物死亡的现象。黑白色长毛狐对溴水化氯醛和水化氯醛比北极狐敏感。每公斤体重静脉注射溴水化氯醛0.3克,水化氯醛0.2克已能引起麻醉10—15分钟。实验也表明溴水化氯醛在与巴巴米或吗啡合并使用时,巴巴米和吗啡可使溴水化氯醛的麻醉期延长,麻醉后的睡眠期长而深。利用北极狐和水豹所做的直肠麻醉,结果符合于Л.М.普列阿布拉任斯基的材料, 即毛皮兽在进行直肠麻醉时部分麻醉剂往往在投药后立即或经20—30分钟被排出体外。

The mortality of the Pohai Sea prawns in autumn has been estimated with avariety of methods. After mating, male prawns die in large numbers. We have found that undersome assumptive conditions the mating mortality of male prawns may be estimated withsex ratio. The results are Iisted in table 2. The mating mortality is about 0.65 in lateOctober. The accumulative value of mating mortality of male prawns is about 1.05 inesrly December. The total mortality of Pohai Sea prawns have been estimated. The results are asfollows. The catch in number per month and catchpereffort as indices of abundanceare regressed against time to calculate the total mortlity. For ten-day average in 10years is about 0.25 for femals 0.34 for mals, and that in 12 ysars about 0.23 forfemals 0.34 for mals. Now we assume that the natural mortality of female prawns maybe negligible in comparison with its fishing mortality, then the total mortality of femaleprawns is approximately equal to its fishing mortality which is about 0.25 per ten-dayperiod in about 800 standard unit of fishing effort. Therefore the catchability is equalto 3.125×10~(-4). After discussing the relationship between mortality and fishing effort, we confirmthat when fishing effort is less than 1000, fishing mortality varies with effort, andwhen fishing effort is greater than 1000, the increase in effort has little influence onfishing mortality. The fact shows that there is a certain limit, being about 0.3perten-day period to fishing mortality with regard to the prawn fishery in the autumnfishing season.

我们用各种方法估算了秋汛渤海对虾(Penaeus orientalis Kishinouye)的死亡值。总死亡系数的估算结果:用渔获尾数为相对资源量估计的10年平均旬死亡值,雌虾约0.25,雄虾约0.34;用y/f为相对资源量估计的12年旬平均死亡值,雌虾0.23,雄虾0.34;用世代分析(Pope 方法)估计的3年雌虾旬平均死亡值约0.30。交尾后部份雄虾死亡,我们找到了一个用性比资料估算雄虾交尾死亡的方法。估算结果,到10月末,雄虾交尾死亡系数约为0.65,并有陆续死亡现象,到12月初的累计死亡系数约1.05左右。我们在讨论了渤海秋汛对虾渔业的 F和f之间的关系后,认为当 f<1000,捕捞死亡随捕捞努力量的变化而变化;当f>1000,捕捞努力量的变化对捕捞死亡已无多大影响,所以渤海秋汛对虾渔业平均每 10天的捕捞死亡系数不能大于0.3。
