(1) The calcium, phosphorus, iron & ascorbic acid contents of 73 kinds of vegetables in Nanch'ang have been determined.(2) The ascorbic acid content of one kind of turnip tops was found to be 187.3 mg/100g and that of small cabbage 106.6mg/100g. The calcium content of the lafter was found to be 185 mg/100g. All these results indicate that such contents of the Nanch'ang vegetables are higher than those of the corresponding vegetables in North China.(3) Pickling causes a decrease of both the calcium and phosphorus contents in vegetables. In salt water at room temperature, the decrease of the calcium and phosphorus contents was found to be 38.8% and 18.1% respectively, while in hot salt water the decrease was raised respectively to 45.4% and 37.9%.

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。

Chinese rape, varieties of Brassica campestris and B. chinensis and many cruciferous crops including radishes, but except varieties of B. oleracea, are generally affected by a mosaic disease, causing serious losses amounting occasionally to a death rate of over 90%, while an infection rate of over 30% is not uncommon. The symptoms involved were vein-clearing, yellow or green veinbanding, typical mosaic, rugosity of leaf lamina, dwarfing and rosetting. They may appear in different combinations. Flower stalks may not come out or are shortened, deformed and twisted. Flowers appeared pale yellow and become abortive, or forming only small and twisted seed pod, which are sometimes spotted with black necrosis, and bearing small and deformed seeds. When the winter temperature is low, diseased plants may succumb first, forming missing hills. Late infections may result only in vein-banding of the upper leaves and partial abortion of the seeds. On several varieties of radish, mostly of the green type, which apparently are more resistant, only fine mottling appears on the leaves while infected. On varieties of B. napella, another oil-bearing group, the symptoms are entirely different (plate 1, fig. 5), appearing as systemic bright yellow spots on the leaves. Necrotic flecking can eventually be found at the center of these spots. Necrotic streaks and spots develop on the flower stalks and seed pods. Dwarfing and distortion occur on leaves, stalks and pods, and death may even be resulted from severe infections. However, this species showed certain degree of resistance to the disease in the form of late infection and the lower incidence of the disease. The viruses from different host plants are cross-inoculable, although some strains do not infect B. napella. None of them can infect the cabbage group by sap inoculation. 3 viruses were identified: differentiated by their physical properties and the host reactions they induced (Tables 1 and 2 for the viruses 1 and 2): 1. Thermal inactivation below 70℃. 2. Producing necrotic local lesions only on N. tabacum var, "Nungling 400" …… virus 1 2. Producing necrotic local lesions and systemic mottling on the same host……virus 2 1. Thermal inactivation above 90℃., necrotic local lesions on N. glutinosa…… virus 3 The first two viruses can be subdivided into 2 strains each by their ability to infect B. napella. Virus 1 is considered to be a strain of Brassica virus 2 or the Turnip mosaic virus; from the type, it differs in not infecting the cabbage group. Virus 2 is identified as a strain of Cucumis virus 1 or the Cucumber mosaic; virus; from the type, it differs in having lower thermal inactivation point (55℃.), lower dilution end point (1: 1,000—3,000); and shorter longevity invitro (2 days), in producing local lesions on tobacco, and in that the typical strain of Cacumis virus 1 gives only a partial protection to this strain on tobacco. The 3rd virus was less studied. It shows affinity to Nicotiana virus 1 or the tobacco mosaic virus. A limited test showed that the first virus was the only virus found present in the field in 1957. An analysis of 17 isolates of virus from the Chinese rape, exhibiting various syndromes of symptoms in the field, gave an Unanimous result in host reactions, indicating that these isolates belong to a single virus. Virus 1 was found to be easily transmitted by sap, by aphids, including peach aphid (Myzus pcrsicae), false cabbage aphid (Rhopalosiphum pseudobrassicae), and cotton aphid (Aphis gossypii). In insect relationship, the virus belongs to the nonpersistent group, a single feeding will enable an active transmission of about 20 minutes. Peach aphid seems to be an effective vector that 2 or more viruliferous aphids per plant are capable of 100% transmission. The virus is not seed-transmitted. Fresh residue of diseased plant in the soil may cause occasional infection of the replanted plants. The virus can infect several cruciferous weeds, but, among them, only Rorippa montana (wall.) Small grows all the year round and possesses a perennial crown. It is also foundto be commonly infected in the nature. Rubbing with infected sap or using aphid as vector, the virus from this weed can easily be transmitted to the Chinese rape, producing the typical mosaic symptoms. This weed, therefore, seems to be capable of beoming a source of inoculum for the primary infection of the Chinese rape.
