Physiology of Plants Affected by Ageing

physiology of plants affected by ageing

objective: ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. accelerated ageing has been recognized as a good predictor of the storability of seed lots. aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. the characteristics of the chemical composition of...

Rat hippocampal GABAergic molecular markers are differentially affected by ageing.

We previously reported that the pharmacological properties of the hippocampal GABAA receptor and the expression of several subunits are modified during normal ageing. However, correlation between these post-synaptic modifications and pre-synaptic deficits were not determined. To address this issue, we have analysed the mRNA levels of several GABAergic molecular markers in young and old rat hipp...

Conservation physiology of plants

Conservation physiology was first identified as an emerging discipline in a landmark paper by Wikelski and Cooke (2006). They defined it as ‘the study of physiological responses of organisms to human alteration of the environment that might cause or contribute to population decline’. Although the case studies and examples presented by Wikelski and Cooke (2006) focused on wild animals, they also...

Physiology and Pathology of Plants

In order to study the effects of solutions on the life processes of a tree it is desirable to introduce them directly into the trunk, since when added to the soil they may be greatly modified and it is often difficult to determine what actually enters the tree. The direct injection of trees and other plants with solutions seemed until recently to offer insuperable difficulties from a practical ...
