Vigour and Pattern in Taxonomy
Journal of General Microbiology, 1968SUMMARY: A method is described for calculating taxonomic relationships based on qualitative characters so as to reduce dissimilarity that is due principally to differences between the strains in growth rate (or other similar factors). By this the total difference is partitioned into two components, ‘Vigour Difference’ and ‘Pattern Difference’, which ...

Morphological and yield characters of eight intervarietal hybrids of brinjal were studied to assess the extent of vigour expressed in different parental combinations. The most economic combination was found to be between Muktakeshi × Banaras giant in which the increase in yield was over 100%.

ABSTRACT Probably no other component of seed quality has been the subject of as much controversy and misunderstanding as seed vigour. Although the complex underlying mechanisms of seed vigour have not been fully described, much progress has been made in our understanding of the phenomenon and its practical consequences.

Seeds start to deteriorate as soon as they have reached peak maturity on the mother plant at a rate which depends on seed moisture content and temperature. Symptoms of reduced vigour include slower and more variable rates of germination, a greater proportion of morphologically abnormal seedlings, and a decreased ability to emerge from seedbeds under ...

A viable seed is one which is capable of germination under suitable conditions. The definition includes dormant but viable seeds, in which case the dormancy must be broken before viability can be measured by germination. A non-viable seed, therefore, is one which fails to germinate even under optimal conditions, including treatments for the removal of ...
