{"title":"[Virus infestation of garden radish (Raphanus sativus L. var. sativus) (author's transl)].","authors":"K Schmelzer","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>In July 1974 a mosaic disease was stated in seed plants of garden radish near Aschersleben which spread more and more within some weeks and eventually infected over 40 per cent of the stand. Investigations in comparison with healthy seed plants demonstrated the following average losses induced by the disease: number of pods 51 per cent, seed weight 67 per cent, number of seeds per plant 53 per cent, weight of 1,000 seeds 33 per cent. Nearly unaffected were: number of seeds per pod, percentage of seed germination, and percentage of emerged seedlings. However, the seedlings were smaller when they derived from diseased mother plants. From diseased seed plants cauliflower mosaic virus was isolated. Seed transmission of this virus could not be stated with several hundreds of seedlings deriving from diseased garden radish. Back transmissions were successful with sap and with aphids. Only one strain which was cultivated in greenhouse for a long time gave no positive results. Three isolates of cabbage black ring virus from different plant species and the four beetle-transmissible viruses, namely turnip yellow mosaic, turnip crinkle, turnip rosette, and radish mosaic viruses induced no symptoms on garden radish seedlings. However, Erysimum latent virus, also belonging to the beetle-transmissible viruses, sometimes caused symptoms in garden radish. For the first time the investigations demonstrated in Europe, but probably also for the other continents, a spontaneous virus infection of Raphanus sativus var. sativus.</p>","PeriodicalId":23868,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.

{"title":"[Lipolytic activity in some Candida strains (author's transl)].","authors":"L Pospísil, A Kabátová","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The authors carried out an examination on the production of lipase in 300 Candida strains. The lipolytic activity was present in the majority of strains. In the 60 of the strains a more precise measurement of lipase production was performed qualitatively in a solid medium according to SIERRA (1957) and quantitatively in a liquid medium by titration with 0.1 N KOH. Furthermore, the correlation was determined between the production of lipase and the Candida growth. It was found that the qualitative proof of lipase in a solid medium according to SIERRA (1957) is a good informative method for determining lipolytic activity in Candidae. A much more sensitive method, however, is the quantitative method in a liquid medium; by this method the authors were successful in determining lipolytic activity even in some cases where the qualitative test was negative. On the whole, Candidae are lipolytically highly active. The mean values of lipase production in the Candida albicans cultures is 622 units in 1 ml of liquid medium; in other strains it is 798 units in 1 ml. There is a direct relation between the density of the culture and the amount of lipase produced.</p>","PeriodicalId":23868,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.

In comparison of farm-yard manure, the liquid manure involves -- a decrease of C and N in the soil, -- a deterioration of the soil structure, -- a dangerous change in the CEC for K+ and Na+, -- an excessive stimulation of the microflora. In brief, through its composition the liquid manure involves a hyperactivity of the microglora. This heterotropic microflora is particularly mineralizing and breaks down the organic matter. The result is a temporary increase in fertility. But this stimulation of the soil life disbalances the eco-system in which -- the pool of organic matter decreases without replacement, -- the content in Ca++ and Mg++ decreases to the benefit of K+ and Na+.</p>","PeriodicalId":23868,"journal":{"name":"Zentralblatt fur Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene.
