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...

This is a further study on the "Kwuting" of Chinese cabbage which has beendemonstrated to be caused by a strain of turnip virus (Turnip virus 1 Hoggan etJohnson).Isolates from the "Kwuting" of Brassica pekinensis,mosaic of B.chinensis,of B.oleracea var.capitata and of Raphnus sativus var.longipinnatus are mixed invarious proportions and inoculated to the Chinese cabbage seedlings.All mixturesproduce the same symptoms and the same degree of severity as Kwuting virusinoculated alone.Therefore in pathogenicity they can only be grouped under thesame strain. When the air temperature in greenhouse is maintained at an optimum (around28℃) of the disease development,a variation of the soil temperature (15°,20%25° and 30℃) by using the modified Wisconsin soil tanks doas influence the degreeof expression of symptoms.However,the influence is more significant in the caseof a susceptible variety as Chiaochowpai,and less in the cases of a tolerant varietyas Chinpaikou and a variety of Brassica chinensis L. During the course of the development of the Chinese cabbage plant,an infec-tion which takes place at the early stage (especially in the stape prior to 7-8leaves),causes far more severe symptoms than in the case of late infections(usually after the starting of heading).This effect is also more pronounced inthe case of a susceptible variety "Chioachowpai". Varietal tests for the resistance to "Kwuting" are crrried out both at Pekingand Hsingchen (Northeast China).According to the results of a two-years-test,it is revealed that four varieties,namely Shangtung No.1,No.2,KungchulingTamayi and Hsingchen Tamayi are highly resistant both at Peking and Hsingchen,whereas a tolerant variety Chinpaikuo shows high tolerance at Peking,but highsusceptibility at Hsingchen.Some commercial varieties which are generally cultiva-ted in north-eastern provinces,such as Chiaochowpai,Heitaoweng and Pantsoutsaiare all highly susceptible.

白菜孤丁病毒与油青菜花叶病毒、甘兰花叶病毒及蘿卜花叶病毒经各种配合的混合接种后,在症状土及發病率上沒有显著的差异,说明它們不但是同一个毒种,而且可能是同一个毒株。土壤温度影响白菜弧丁的發病,土温在30℃时,高度感病的胶州白菜的發病几乎比在15℃的土温高出一倍。但这种关系在耐病的青白口上,以及感病的另一菜种油青菜(Brassica Chinensis L.)上,則不显著。白菜在幼苗期受侵较后期受侵的發病严重,但这种影响也是以高度感病的品种为显著,例如胶州白菜在8月29日接种的比在10月23日接种的病情指数高一倍多。这种关系对耐病的青白口及高度抗病的山东二号说来,在北京田间情况下不明显。在北京和辽宁兴城两地經1954及1955两年的比較試驗,选出了高度抗孤丁病的山东一号及二号、公主岭的大麻叶及兴城的大麻叶等4个品种。北京的青白口在北京地区是一个耐病的品种,但在兴城則失去其耐病性。山东著名的胶州白菜是一个高度感病的品种,其他如东北的半矬菜在兴城、徐水的白帮核桃纹在北京都是高度感病的。

The correct limit of U(t,t0) is obtained without introducing any adiabatic device when the limit t0→±∞ is properly taken. Discussion are given on the properties of the special limiting process proposed by Gell-Mann and Goldberger.In addition, the formal expression of U(t,t0) and its limit is generalized to comprise various forms of perturbation formalism of damping and scattering.
