[Prevalent forecast of kiwifruit bacterial canker caused by Pseudomonas syringae pv. actinidiae].

The prevalent analysis of kiwifruit bacterial canker for several years showed that the effective ecological factors of severe degree were the precipitation (x1) in the second and last ten-days of March, and the average temperature (x2) of January. The model was y = 2.1359 + 0.0107x1 - 0.6061x2. The main factor of the prevalence was the relative variation of ten-days average temperature and precipitation in Winter and in early Spring, and the regression equation was y = -8.127 + 22.739x - 13.254x2. The forecast effect of the equation was obviously significant after testing.

[Ecological factors affecting prevalence of kiwifruit bacterial canker and bacteriostatic action of bacteriocides on Pseudomonas syringae pv. actinidae].

According to the systematic study for 5 years, this paper dealt with the ecological factors affecting prevalence of kiwifruit bacterial canker. The disease was more serious in the orchards with above 750 m in elevation, and more serious at mountain slope facing south than facing north. Incidence differed significantly among cultivars, with easy disease infection for Jinfeng, and strong disease resistance for Jinkui. The older the trees, the more the diseased plants. The one year old twigs had highest death twig incidence of diseased twigs and death twig incidence than other twigs. Among 6 tested bacteriocides, Jiaruinong and streptomycin showed best bacteriostatic effect.

[Formation of a new antibiotic, nocamycin, by a culture of Nocardiopsis syringae sp. nov].

A culture of a new actinomycetous species, Nocardiopsis syrinage was isolated from a soil sample. The antibiotic produced by it was named nocamycin. It accumulated in the culture fluid on cultivation of the organism in a nutrient medium containing soybean meal, glycerin, sodium chloride and calcium carbonate. Crystalline nocamycin had an antitumor effect. In inhibited by 72--73 per cent the development of an intraperitoneally implanted lymphadenosis of strain NK/LI in mice.
