The rationality of the corresponding moduli variety is proved.
      
If the additive group of complex numbers acts algebraically on a normal affine variety, then the associated ring of invariants need not be finitely generated, but is an ideal transform of some normal affine algebra (Theorem 1).
      
We investigate such normal affine algebras in the case of a locally trivial action on a factorial variety.
      
If the variety is a complex affine space and the ring of invariants is isomorphic to a polynomial ring, then the action is conjugate to a translation (Theorem 3).

This preliminary study of the influence of spikelet pruning on the quality and yield of wheat grains was carried out at Fukien Agricultural College in October 1952 through May 1953. The results are summarized as follows: 1. The number of grains increases in each spikelet as a result of pruning. 2. Size, weight, and protein content of the grain increase both with the difference in variety and the dates of planting. 3. Treated wheat plants ripen earlier. 4. The total yield decreases slightly. This is probably...

This preliminary study of the influence of spikelet pruning on the quality and yield of wheat grains was carried out at Fukien Agricultural College in October 1952 through May 1953. The results are summarized as follows: 1. The number of grains increases in each spikelet as a result of pruning. 2. Size, weight, and protein content of the grain increase both with the difference in variety and the dates of planting. 3. Treated wheat plants ripen earlier. 4. The total yield decreases slightly. This is probably due to the fact that the gain in weight of grains does not overcome the loss of weight by the removal of some of the spikelets,

The rice stem borer, Chilo simplex Bulter, is one of the important rice pestsin Kiangsi. The relative proportion of this borer to Schoenobius incertellus Wk. isgradually increased especially after developing the movement of "Control the RiceBorer by Plowing in Autumn, Winter and Early Spring." This situation induced usto take up this problem. This paper deals with the distribution of the borer Chilo simplex with a dis-cussion of the factors influencing its distributional population. in Kiangsi. The lifehistory, behavior of the borer and its relation to Zizania latifolia Hence are also givenin detail. Zizania latifolia is a good shelter for overwintering larvae of the borer,so it is better to discourage the cultivation of this plant in the rice area, or to treatits stubbles soon after harvest or in late March the following year.

(一)二化螟在江西的分布情况,根据三年来的考察,在比例上较三化螟有逐渐扩展的趋势。此项原因,与江西三年来厉行三耕的结果是分不开的。因三耕后,三化螟大部死亡,二化螟则在越冬期中的顽强性大,能逃逸到其他杂草根部去躲藏,所以死亡率不高。 (二)同地区二化螟的分布密度,常因水稻品种的不同、栽培制度的不同、早晚稻的不同、以及周围有无菱白而发生差异。一般糯稻与粳稻中的二化螟分布密度,较高于籼稻;一季晚籼和一季晚糯的二化螟数目,又高于二季晚籼;早稻枯心苗中极少三化螟,晚稻枯心苗中渐多,到晚稻遗株中,则又往往超过了二化螟而占优势。 (三)菱白为二化螟及大螟的越冬大本营,能提早该地区二化螟第一代幼虫的发生期,增加该地区二化螟发生化数,又能使周围水稻田中,二化螟的数量增多,故稻区最好不种菱白。如果一定要种,则必须注意处理它的越冬遗株。处理的方法,根据二化螟及大螟在越冬前后部位的转移情形,抓紧在10月底前或5月底后,将菱白地上部位齐泥割去,深埋土下,或晒乾烧去,即可免其变蛹羽化,继续加害。

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...
