Book Description
The second part deals with the relationships between environment and infection. Resting spores germinated more rapidly if dried and apparently only in the presence of host roots. In air-dry soil resting spores survived 56 days at -24°C. Minimum, optimum and maximum temperatures for infection of roothairs were below 11°, 14°- 20°, and 22°-25°, respectively. Between pH values of 5.2 and 7.5, soil pH had hardly any influence on invasion of root-hairs. At 16° to 20° the incubation period for tuber and root infection was less than 3 weeks.

Book Description
Now established worldwide as the standard guide to the recognition and understanding of the causes of deterioration in temperate and tropical fruits and vegetables, these two superbly illustrated full-colour volumes deal clearly, concisely and systematically with each of the main diseases and disorders, emphasising those of importance to international trade. Dr Snowdon has designed each volume to be used in two different ways: 1. Full colour photographs and practical text provide the basis for preliminary identification by the owner or surveyor. 2. Using the microscope drawings and references, diagnosis can then be confirmed or modified by a specialist.

The Mycetozoans
Author: Lindsay OlivePublisher: Elsevier
ISBN: 0323156738
Category : Nature
Languages : en
Pages : 305
Book Description
The Mycetozoans brings together, for the first time in a single volume, comprehensive information on the biology and classification of the mycetozoans and associated groups. The mycetozoans and their associates remain of prime interest to taxonomists and phylogenists because major new taxa continue to be discovered among them. This book informs the reader where to find mycetozoans, how to isolate and culture them, their life cycles and ultrastructure, and some of the experiments that may be performed with them. It presents studies on Protostelia (protostelids); Dictyostelia (dictyostelid cellular slime molds); Myxogastria (myxomycetes); Acrasea (acrasid cellular slime molds); Plasmodiophorina (plasmodiophorids); and Labyrinthulas (labyrinthulina and thraustochytrids). This text can serve as a reference tool in courses on mycetozoans, protozoology, mycology, and developmental biology of lower organisms, and as a concentrated source of information for research workers in all aspects of the biology and taxonomy of these organisms.
