A rain tower and wind tunnel for studying the dispersal of plant pathogens by rain and wind
The rain tower/wind tunnel complex at Rothamsted consists of a rain tower (height 11 m, cross-section 1 m2) linked to the upwind end of a wind tunnel (length 12 m, cross-section 1 m2), which may be operated in either an ...
Factors affecting the germination of Septoria nodorum pycnidiospores
Most pycnidiospores of Septoria nodorum were released from pycnidia into water in 30 min, more than 50% being released in 10 min. The viability of pycnidiospores in aqueous suspension, assessed by germination on a selective ...
Effects of rainfall intensity and duration on dispersal of Rhynchosporium secalis conidia from infected barley leaves
Simulated rain of two intensities was allowed to fall for 30 min on to barley leaves infected by Rhynchosporium secalis. The resulting splash droplets were collected on horizontal pieces of fixed photographic film. Most ...
Preferential association of apocytochrome c with negatively charged phospholipids in mixed model membranes
The mitochondrial precursor protein, apocytochrome c, binds to model membranes containing negatively charged phospholipids (Rietveld, A., Sijens, R., Verkleij, A.J. and Kruijff, B. (1983) EMBO J. 2, 907-913). In the present ...
Effects of irrigation and benomyl treatment on chocolate spot (Botrytis fabae) and yield of winter-sown field beans (Vicia faba)
In 1976-7, 1977-8 and 1978-9 plots of winter-sown field beans, either irrigated in June and July or unirrigated, were treated with one or more sprays of benomyl or were untreated. The amounts of chocolate spot on field ...
Effects of leaf age, inoculum dose and freezing on development of chocolate spot (Botrytis fabae) lesions on field bean (Vicia faba) leaves
Botrytis fabae spore suspensions containing c. 1, 10, 102, 103, 104, 105, or 106 spores/ml were used to inoculate 5, 17 or 30-day-old field bean leaves. The percentages of the leaf areas covered by, chocolate spot lesions ...
Age of onset of schizophrenia in siblings: A test of the contagion hypothesis
The possibility that schizophrenia is horizontally transmitted has been assessed in an analysis of age of onset in 264 recorded pairs of siblings with the disease. Age of onset was found to be correlated between siblings, ...
The development of eyespot (Pseudocercosporella herpotrichoides) lesions in winter wheat crops
The development of eyespot (Pseudocercosporella herpotrichoides) lesions on main shoots of plants in winter-sown wheat crops in 1981/82, 1982/83 and 1983/84 was studied by recording the incidence and penetration of leaf ...
