Considerable difficulties caused by unstable reactions of wheat varieties were encountered by the authors in the study of physiologic specialization of Puccinia glumarum. The fluctuation of varietal reactions was chiefly due to the variation of light and temperature in ordinary green house. It was found that strict control of temperature (constantly at 15℃) and a stable light source were necessary. Fluorescent lamps serves as a good source of cool light, and a daily supply of 16-hours illumination with an intensity of 4,000 Lux is sufficient for normal development of infection-types. Temperature plays most important role among the environmental factors causing the variability of varietal reactions of wheat to stripe rust. In general, wheat varieties become more resistant to stripe rust as the temperature raises from 10℃ upward. The critical temperature at which host reactions changed from susceptible to resistant varied with different combinations of wheat varieties and races of P. glumarum. Eight variety-race combinations out of 60 had their infection types changed from susceptible to resistant at 15℃, 15 combinations changed at 20℃, 18 combinations at 25℃, while 16 combinations had their resistant infection types unchanged under different temperatures. Highly resistant wheat varieties such as Early Premium, Li-Yung 1, Naking 4179 remained resistant to all 4 races tested under a wide range of light intensities, while highly susceptible variety Ycnta 1885 remained susceptible throughout. Other susceptable varieties behaved rather specifically as light intensity and daily length of illumination varied. Infection type, amount of sporulation and range of cnvironmental conditions for sporulation should all be considered as criteria for the exact evaluation of varietal resistance of wheat and pathogenicity of rust races. Race Y6B isolated from wheat vareity Pima-1, has been proved to be a dangerous race, causing Pima strains severely diseased at 10°—20℃, with the capability to sporulate at 25℃. Race Y6, of which the pathogenicity resembled that of race Y6B on 6 differential hosts, had been(?)olated from Shantung and Shansi provinces during 1954—55. These findings correlated well with the breakdown of Pima 1 in resistance to stripe rust over a wide geographic area since 1955. Early Premium, Naking 4197, Liyung 1 and Nungta 6 are highly resistant varieties to race Y6B.

試驗証明温度和光对小麦品种抗条銹病性的影响极大。由于小麦品种对条銹菌不稳定反应所造成生理鑑定小种的困难,基本上可通过严格控制温度和光获得解决。条锈菌生理小种的鑑定最好在15℃恆温和恆光的設备下进行。用日光灯为光源,光強度保持4,000 Lux,每日照射16小时即已足够使小麦品种正常发病。当温度逐漸提高时小麦品种漸由感染变为抵抗。由感染型变为抵抗型的温度轉变点因品种和生理小种的不同組合而有差异,在60个品种小种組合中,自15℃起变为抵抗型的有8个組合,自20℃起变为抵抗型的有15个組合,在25℃下变为抵抗型的有18个組合,在10—25℃温度范围內均为抵抗型的有16个組合。高度抗病的品种如早洋麦、金大4197、驪英一号等在所有光強度(日光40.000 Lux及鎢絲灯与日光灯組成人工光強度为8,000 Lux、6,500 Lux、5,000 Lux、2,500 Lux和1,200Lux.)及各种不同光照时間下(日光灯为光源,4,000 Lux,不同光照时間每日为8、12、16及24小时)均抗病。高度感病品种燕大1885則在所有光強度及各种不同光照时間下均为感染型。孢子产生的数量則随光強度和光照时間的增加而增多。其他...

Stunty rice plants commonly grown in the fields of mountainous regions of northern Fujian were carefully investigated for the cause in this paper. Characteristics of this physiological malady and its distribution were studied. Reasons of its formations were summarized in final systematic types,The aim of this investigation is to supply valuable experimental data to check this physiological malady with a fundamental idea of promoting high rice yield ecosystem in northern Fujian,as well as protecting the rice-growing industry in such regions. Results reveal that “Stunty green rice model” is due to deficiency of available phosphorus,and “Stunty yellow rice model” is due to deficiency of available sulfur,nitrogen or low temperature stress of the air as well as the earth.Such types of malady are resulted from characteristic topographic cnvironments-soils-land utilization and management systems.According to analysis of sporadic rate,wide sporadic rate,and great covering areas of rice plants,they have the peculiarities of wide distribution and complex origins.The combination of the stress is not only complicated but also universal in occurrence.In northern Fujian,such defective rice fields come from cold stress of low air and soil temperature,deficient mineral elements, toxic elements and destruction of soil ecological balance.Thus they lead to the physical abnormality of soil media,defects of available soil water, soil temperature,and nutritional status.Soil carbon nitrogen,phosphorus, sulfur as well as other mineral contents and their relative amounts are in disoroder.The results of such conditions come from complicated interactions of environmental dificiencies of light and temperature together with available water defects.Thus the improper utilization and management of land accelerate the barrenness of the soil,leading to stunting.From various aspects,the authors assumed a system of stunting field classification.They form two main groups,with four subtypes and eleven sorts or species. Mixed curative methods were presented recommending the main procedures as well as emergency measures.

本文探讨了长期存在于闽北山区的一群病态稻田——发僵田的障害实质;发生分布特征及形成因素;最后总结阐明了有关其障害机制类型简明系统。本文的研究目的是为这类病田的正确施治提供实验根据,而其实际意义还涉及闽北高产稻田生态系统的创造与维护。研究结果表明,闽北稻绿型发僵是由土壤缺少有效磷,而稻黄型发僵是由土壤缺少有效硫、氮或强烈冷害引起的;这类病田是特球的地域性环境——土壤——土地利用管理体系作用下的必然产物。据发生片率(频率)、面率及成片度的调查分析,它们具有分布广泛而发生类型复杂特点,从而揭示了这类病田在闽北有着特别广泛的发生因素和复杂的障害组合。此类稻田对水稻生长的障害,可概括为存在于环境——土壤中的冷障、缺素与毒质的作用,及正常土壤生态平衡之破坏。有关后者的重要情况是土壤基质物理、水热状况和营养化学性质有严重缺陷,尤其是土壤碳、氮、磷和硫的含量和比值的失常。这一状态的产生根源是环境光热不足,水文状况复杂,土壤普遍贫瘠化;而落后的农田利用管理是其强有力的促成因素和稻发僵的“导火线”。作者根据各方面研究结果而拟订的僵田分类系统,包括了两大类四个亚型共11种。在最后总结中指出了综合施治的基础、中心环节及应急措施。

The photosynthetic and photorespiration rates of flag leaves of three varieties of rice, i.e. Guangluai No. 4, Zhenzhuai No. 11, and IR-24, under four light intensities (35, 40, 45, and 50 Klx) and three temperatures (30℃,35℃. and 40℃) were measured with potted rice plants in the laboratory. It was found that all three varieties showed light saturation at about 45 Klx under three different temperatures. But the photosyntheysis of these three varieties responded differently to differing combinations of light...

The photosynthetic and photorespiration rates of flag leaves of three varieties of rice, i.e. Guangluai No. 4, Zhenzhuai No. 11, and IR-24, under four light intensities (35, 40, 45, and 50 Klx) and three temperatures (30℃,35℃. and 40℃) were measured with potted rice plants in the laboratory. It was found that all three varieties showed light saturation at about 45 Klx under three different temperatures. But the photosyntheysis of these three varieties responded differently to differing combinations of light and temperature conditions. The highest photosynthetic rate of Guangluai No. 4 was found at 35℃ under all four light intensities, that of IR-24 at 30℃. The variety Zhenzhuai No. 11 seemed to be more tolerant to temperature fluctuation,with only a relatively small change of photosynthetic rate under these three temperatures. The relative photosynthetic rates of these three varieties differed under differing conditions. Under 30℃, the photosynthetic rate of the variety Guangluai No. 4 was relatively lower than that of the other two varieties, but under 35℃ the reverse was true. Uuder optimum temperature and saturated light intensity, the highest photosynthetic rates attained were 26.7, 21.9, and 21.8 mg CO 2 dm-2, hr-1 for the varieties Guangluai No. 4. Zhenzhuai No. 11 and IR-24 respectively. The highest photorespiration rates were found at 35℃ for all three varieteis. The variety Guangluai No. 4 had the lowest photorespiration rate and relatively lower CO2 compensation point. Discussion was made on the combined effects of light intensity and temperatuce on photosynthesis of rice.

本文报道广陆矮4号、珍珠矮11号、IR—24三个水稻品种的剑叶在不同的光照强度(35,000、40,000、45,000、50,000勒克斯)和30℃,35℃,40℃三个不同温度下的光合作用和光呼吸的变化情况。在三个温度下测得三个品种的光合作用光饱和点均在45,000勒克斯左右。在不同温度和不同光照的综合条件下,三个品种的光合强度变化情况不同:广陆矮4号的光合作用在35℃下最强,在四个光强下均是如此;IR—24的光合作用则在30℃下最强,在四个光强也是如此;珍珠矮11号的光合作用在三个温度下变化不大。在饱和光强和不同温度下,各品种的相对光合强度也不同。在30℃下广陆矮4号的光合作用比其他二个品种稍弱,但在35℃下则相反,其光合作用强于其他二品种。在最适光、温条件下,广陆矮4号、珍矮11号和IR—24的光合强度分别为26.7、21.9、21.8mgCO_2/dm~2/小时。三个品种的光呼珠吸均以在35℃为最强,其中以广陆矮的光呼吸最弱,二氧化碳补偿点亦较低。本文对光、温条件与水稻光合作用和光呼吸的关系,以及各品种对光、温条件的不同要求进行了讨论。
