Although most higher plants are hermophroditic, monoecious or dioeoious plants are not infrequently met with in nature. In some cases, plants or organs of one sex possess greater economic value than those of the other sex. Therefore, to change the sex of plants or vary the numbar of either male or female flowers (usually toward the direction of femaleness) is of both theoretical and practical significance.It has long been observed that the sexuality of plants changes with a change of environmental factors. But those -observed facts received little attention in the past, since they could not be reconciled with the then-prevalent chromosome theory of sex determination. Biologists of the Michurin school believe .that sexuality of plants is but one of the characteristics that the plant exhibits under certain environmental conditions. Thus, like any other characteristic, it is determined by the metabolic conditions of the plants themselves. We are convinced that by changing one or more of the environmental factors, thereby altering the metabolic pattern of the plants, we can successfully control the sexuality of plants for the banefit of mankind.Minina in her monograph has comprehensively reviewed the literature pertinent to the change of sexuality in the plant world under changed enviromental conditions. It has been shown that either treatment with CO, or an alteration of the nutritional status of plants can affect the sex expression of plants.The present investigation purposes to study in greater detail the principles governing the formation of male and female flowers in the cucumber plants.Treatment of the 24-day-old cucumber seedlings with CO gas (at 1%, 0.5% and 0.3%) for 161 hours has remarkably altered the order in which the mala and .female flowers appear. The numbar of female flowers greatly increases, whereas the male flowers do not appear until much later. Marked morphological changes have also been noticed. Physiologically, treated young plants decrease their respiratory activity by 50-70%, as measured at the close of the experimental period. The activity of catalasa has had corresponding changes.When plants are given ample phcspliorus fertilizer successively at the 3-leaf stage, the. stage of bud appearance, and the stage of opening of the female flowers, they bear much more female flowers, whereas the number of male flowers remains unchanged. Plants thus treated also show lower calalase activity hi their leaves.Higher water content of the soil has favored the formation of female flowers. Plants grown under such condition absorb more nitrogen than control plants. This is in line with what is reported in the literature to the effect that high nitrogen is favorable for the development of femaleness.The increase of the number of female flowers is not necessarily connected with the state of the growth of plants. This has led us to believe that it is not the general nutritional status of plants, i.e., the abundance or deficiency of fertilizer, that determines sexuality,The present investigation has clearly demonstrated the possibility that different environmental factors which showed their effect on sex expression may have performed their functions through the same or similar mechanism.The effects of some respiratory inhibitors, including NaN3, malonate, fluoride, etc. are being examined. Investgations are also being undertaken to elucidate the possibility of treatment of seeds with various substances to change the sex ratio of the flowers in the cucumber plants.

在自然界中不少植物是雌雄异株或雌雄同株而异花的。不同性别的植株或花的经济价值不同,因此,定向改变植物性别的问题就不仅仅具有理论上的意义,而且也有着实践上的意义。很早就有人观察到植物性别可随环境而发生改变的事实;但是这些事实没有受到足够的重视,因为它们与性别决定的染色体学说是不相容的。米丘林生物学者认为植物性别的形成和发展也是植物有机体在一定环境条件下所表现的发育特性之一,是决定于植物体内的新陈代谢的。因此,我们深信,通过环境条件的改变,改变植物体内的新陈代谢过程,从而定向地控制植物的性别是完全可能的。 曾详尽而全面地介绍了定向改变植物性别方面的文献。本文目的在于进一步探讨环境条件对于黄瓜雌雄花出现的规律性的影响以及这些影响的生理实质。 在黄瓜幼苗期间用CO(浓度为1%,0.5%,0.3%)处理植株161小时显著地改变了雌、雄花出现的顺序,增加了雌花的数目,降低了雄花的数目。提高了果实的产量。在外部形态方面亦发生了显著的改变。在生理方面,遭受气体处理的植物在处理结束后呼吸强度降低50—70%,过氧化氢酶的活性也有相应的改变。 在植株三叶期、现蕾期、雌花开放期均施以充足的磷肥,这种处理选择性地增加了雌花的数目,而...

1. This article reports the observations of the early (5, 30, 60 minutes and 6 hours) reactions of the male germ cells of the white mice to a single dose and whole-body irradiation. The conditions of irradiation are: voltage, 140 kvp; current, 11 ma; dose rate, 100 r/min.; distance, 46 cm; and the effective dosage, 600 r. As fixative we use FAA and the paraffin sections are stained with method of Feulgen reaction, counterstaining with fast green.2. In the sections of the testes fixed at the intervals of 30 and 60 minutes after irradiation we observed within the seminifereous tubules the germ cells of different developmental stages having various reactions: (a) the spermatogonia may form the chromosomal bridges at the anaphase of mitosis; (b) the spermatocytes at the growth period may undergo pycnosis, nuclear swelling, reversion of pachytene nucleus to the resting state, or formation of syncytia; at the time of meiosis, they either form chromosomal bridges, possess irregularly distributed chromosomal clumps, or die at the stopped metaphase; (c) the spermatids and the developing sperms may appear pycnotic, undergo nuclear or cytoplasmic vacuolization, form syncytia, or enclose one or more anormalous nuclei, resulting from the lag or abnormal development; (d) the mature sperm, the Sertoli cells, as well as the interstitial cells are not affected. 3. The cells of the same stage are subjected to the various degrees of radiation injury and the mode of their reactions is also various.4. The problems, such as the cellular radiosensitivity, the mitosis and the expression of the radiation effects, and the action of radiation on cytoplasm and nucleus, are tentatively discussed.

1.本文系报告用X射线一次全身照射小白鼠以观察其睾丸中生殖细胞对600伦X射线照射后的早期(5分钟、30分钟、60分钟、6小时)反应。照射条件为:电压140千伏,电流11毫安,出射率100伦/每分钟,距离46厘米,有效剂量600伦。固定剂用FAA;用孚尔根反应着色,快绿作补染。 2.在照射后30分钟及60分钟固定的睾丸制片中观察到精小管内不同发育阶段的生殖细胞有各种反应:(1)精原细胞在分裂后期形成染色体桥;(2)精母细胞在生长期呈固缩,核胀大及返回休止态,组成合胞;在分裂时形成染色体桥,染色体凌乱分布,中期滞死等等;(3)精子细胞与发育中的精子表现固缩,胞核或胞质空泡化,形成合胞,核畸形(变态延缓或失常);(4)成熟的精子,支持细胞和间隙细胞不受影响。 3.同一发育阶段的细胞受到射线的伤损程度不同,反应的方式亦不一致。 4.对于细胞的辐射敏感性,有丝分裂与辐射效应的表现,以及辐射作用对于胞质和胞核的影响等问题作了初步的讨论。

This paper has been prepared as a supplement and rectification to "PreliminaryObservations on Faunal Regions of Termites in Southern Part of China" published by thesame authors in 1957. In the first part of this paper, based on the conceptions of "Quality, Quantity,Time, and Space" to study the subject, an attempt has been made to define tentative-ly the terminology" the Fauna of the Insect". The term is used here to designate the specific forms and number of the insect or-ganism in a certain space at a moment. Classifying insects into different Faunal regionsis to give expression to the forms and number within a certain taxonomic unit of variousdimensions by systematic grading, thus showing the identity and particularity of eachother and possibly interpreting the law of their development in course of time. The Faunal Region of Isoptera has been tentatively divided into five grades: 0. Supplemental grade--Kingdom 1. World grade--Region and Sub-region 2. Termo grade--Zone and Sub-Zone 3. Eco-pattern grade--Eco--fauna and sub-ecofauna 4. Domicile grade--Habitat In the second part of the paper, a modified scheme for classifying the Faunal regionsof Isoptera in China is presented. The Isoptera in the above-mentioned district has been classified on the degree ofeco-fauna for the time being with taxomical genera as its basis. And a brief accountof the geographic locations of different eco-faunae, their composition and economic im-portance has been given. The following figure is presented to outline the Faunal regions of Isoptera in China. Finally, the geographic origin of Rhinotermitidae, the distribution characteristics ofMacrotermitinae and the relationships between Isoptera in China and those of other sub-regions of Oriental region are discussed. The newly-proposed central-China sub-region is the one besides the four existing sub-regions, the boundary in the eastern part of China between Palaearctic and Orientalregions is determined to be some where about 35°North latitude.

本文首先以质、量、时、空的概念,为区系加以定义。就等翅目进行了区系的系统等级划分。简述了各区系间的地理位置、种属组成、生态特性和其经济意义。从不同分布地区存在着的物种形式与组成和数量的差异,分析它们和社会主义建设的关系。最后讨论了犀螱科的地理来源,大螱亚科在我国分布的特色及我国南方等翅目区系与其他东洋热带地区等翅目区系的亲缘关系。至于作者等新拟的华中亚区,是东洋区现有四亚区的另一亚区,主张古北区和东洋区在我国东部的分界线约在北纬35度左右。还对等翅目中文定名作了建议。
