STUDIES ON THE PROPERTIES OF SOIL‐BORNE VIRUSES OF THE TOBACCO‐RATTLE TYPE OCCURRING IN SCOTLANDSoil‐borne viruses of the tobacco‐rattle type occur in sandy and peaty soils in many parts of Scotland, and infect many species of crop and weed plants, often only in the roots. They also occur in potato plants that have diseases of the stem‐mottle type. The viruses can be distinguished from other soil‐borne viruses occurring in Britain by the symptoms they cause in tobacco, C... ...

The effect of certain antibiotics on reproduction of the black bean aphid, Aphis fabae Scop.SUMMARY The antibiotic terramycin at 0.2% concentration was consistently effective in greatly reducing the populations of Aphis fabae on Vicia faba when sprayed on larvae on and off the plant. The insects were not killed, but their fertility was decreased by over 97% in the first generation, leading to total ster... ...

Abundant genetic diversity of the wild rice Zizania latifolia in central China revealed by microsatellitesAbstract Wild rice Zizania latifolia is a perennial emergent aquatic plant widely distributed across China. Wild populations of Z. latifolia are important to aquatic ecosystems and are valuable genetic resources for breeding. However, they have been faced with significant habitat losses in recent decades. For 10 ... ...

STUDIES ON THE IMPORTANCE OF WILD BEET AS A SOURCE OF PATHOGENS FOR THE SUGAR‐BEET CROPBeet yellows virus, beet mosaic virus, rust (Uromyces betae (Pers) Lév.), and downy mildew (Peronospora schachtii Fuckel.) were found to be common in wild beet (Beta vulgaris s.‐sp. maritima L.) growing on the foreshores of south Wales and southern England. The virus diseases were mo... ...

THE CALCULATION OF THE DOSAGE‐MORTALITY CURVESummary. The sigmoid dosage‐mortality curve, secured so commonly in toxicity tests upon multicellular organisms, is interpreted as a cumulative normal frequency distribution of the variation among the individuals of a population in their susceptibility to a toxic agent, which susceptibility is inversely proportional to the logarithm of the dose applied. In support o... ...

Race non‐specific resistance of oats to primary infection by mildewSUMMARY A range of oat species, species hybrids and derived addition lines, varied in their level of race non‐specific resistance to mildew. This resistance prevented attempted primary penetration by a proportion of spores. It was generally expressed more strongly in fifth than in first formed leaves and thus appeared to be a component of adult plant resistance. Pen... ...

II. Cereal disease: the interplay between resistance and pathogenicity: Some effects of host resistance on the development of oat mildew
Annals of Applied Biology - Tập 94 Số 2 - Trang 290-293 - 1980
Effects of host resistance on the development of haustoria and colonies of oat mildewSUMMARY Colony development of Erysiphe graminis f.sp. avenae race 2 was studied on detached leaf segments of a range of Avena hosts with different levels of resistance, none of which possesses known specific gene resistance to this race. Resistance affected the length attained by mature... ...
