Comparison of ripening processes in intact tomato fruit and excised pericarp discs
(1990-12-01)
Physiological processes characteristic of ripening in tissues of intact tomato fruit (Lycopersicon esculentum Mill.) were examined in excised pericarp discs. Pericarp discs were prepared from mature-green tomato fruit and ...
Expert system supervisory control of the Wheal Jane tin concentrator
(1990-11-22)
This paper reports computer simulation and modelling techniques used at the Wheal Jane tin mine in Cornwall to improve processing efficiency.
Strategies for control of eyespot (Pseudocercosporella herpotrichoides) in UK winter wheat and winter barley
(1990-10-31)
This review considers strategies for control of eyespot (Pseudocercosporella herpotrichoides) in winter wheat and winter barley in the UK. Varietal resistance to eyespot may take the form of direct resistance to the growth ...
The Development of Eyespot on Seedling Leaf Sheaths in Winter Wheat and Winter Barley Crops Inoculated with W-type or R-type Isolates of Pseudocercosporella herpotrichoides
(1990-10)
In 1986–88 the development of eyespot lesions in winter wheat or winter barley differed plots inoculated with W-type isolates of Pseudocercosporella herpotrichoides and plots inoculated with R-type isolates. In the spring ...
Effects of potassium sorbate and environmental factors on growth of tobacco spoilage fungi
(1990-10)
Potassium sorbate was found to inhibit germination and growth of a range of spoilage fungi isolated from tobacco below pH 5. However, at and above pH 5 the efficacy of potassium sorbate was influenced by substrate composition ...
Utilization of potassium sorbate by tobacco spoilage fungi
(1990-10)
Aspergillus, Eurotium and Penicillium species (total of 11 isolates) were examined for their ability to utilize potassium sorbate as a sole carbon source in liquid culture, under different pH and temperature conditions. ...
Molecular organisation of an A mating type factor of the basidiomycete fungus Coprinus-cinereus
(1990-10)
The Aα3 and Aβ3 genes, which together constitute the A42 mating type factor of Coprinus cinereus, were isolated from a cosmid genomic library by walking 50 kb, a map distance of 0.5 units, from the closely linked metabolic ...
