PHYSIOLOGICAL CLASSIFICATION OF DORMANCIES IN INSECTS

The Canadian Entomologist, 1971
AbstractA new classification of dormancy in insects is proposed on the basis of the evolutionary nature of dormancy, its synchronization with the aetiology of the species for their phenological advantage, the nature of ecological adversity, and the consequent physiological and biochemical adjustments. The roles of the above factors in the induction and

Physiological regulation of potato tuber dormancy

American Journal of Potato Research, 2004
At harvest, potato (Solanum tuberosum L.) tubers are dormant and will not sprout. As the period of postharvest storage is extended, tuber dormancy is broken and sprout growth commences. The loss of tuber dormancy and onset of sprout growth is accompanied by numerous biochemical changes, many of which are detrimental to the nutritional and processing ...

Physiological Adaptation and Partial Dormancy in Ascaris Eggs

Nature, 1967
PHYSIOLOGICAL adaptation of the rates of life processes in response to changes in environmental temperature is now known to be commonplace in poikilothermic organisms1. Animals, plants and micro-organisms experimentally subjected to a change in temperature within normal viable limits initially show modified rates of metabolic functions which, in the ...

Assessment of Dormancy Level and Germination Ability of Seeds with Physiological Dormancy

Germination test is fundamental and commonly used technique for seed dormancy and germination studies, and proper assessment of dormancy level and germination ability of a given set of seeds is prerequisite for most of the studies. However, germination is very sensitive to imbibition conditions, and dormancy development is also sensitive to growth ...

Physiological Ecology of Seed Dormancy and Longevity

1996
Studies of seed biology represent a sizable part of existing botanical research due to the importance of seeds for plant propagation, forest regeneration, and conservation. From an ecological perspective, knowledge of plant community structure, dynamics, and succession must include information about plant reproduction, dispersal, and establishment in ...

Bulb Dormancy and Storage Physiology

2018
In reports on onion bulb dormancy the workers seemed generally to follow the latter definition of Emilson but the use of the terms rest and dormancy is very complicated and sometimes confusing. Aoba, T. made a morphological study of bulb formation in onion.

Physiology of Seed Dormancy in Heliotropium eichwaldi Steud

Biochemie und Physiologie der Pflanzen, 1977
Summary Seed dormancy in Heliotropium eichwaldi is dependent on the endogenous level of promoter and inhibitor. These seeds posses a water-soluble inhibitor requiring light for its activity. Indirect evidence also showed the presence of one or more light-activated inhibitors which were not water-soluble. The seed dormancy in H.

A review of the physiology of potato tuber dormancy

Annals of Applied Biology, 1996
Summary.A review of the scientific literature relating to the physiology of potato (Solanum tuberosum) tuber dormancy is presented. Effort has been concentrated on an up‐to‐date overview of the current state of understanding, rather than comprehensively covering the very extensive literature going back over many decades.

THE PHYSIOLOGY OF DORMANCY IN THE SWEETCLOVER WEEVIL

Canadian Journal of Zoology, 1956
The physiology of the overwintering adult stage of Sitona cylindricollis (Fahr.), the sweetclover weevil, has been examined. It has been shown that the dormancy is characterized by a drop in oxygen consumption, a cessation of development in the reproductive organs, and a slight rise in fat content; and that the termination of dormancy is characterized
