Effect of seeding date on canola seed quality and seed vigour

Canadian Journal of Plant Science, 2004
Seedling vigour is a key critical component to produce well-established canola (Brassica napus) seedlings under less than ideal conditions in western Canada. Our objective was to determine if seed lots from late October (fall) or early spring (April) seeding dates improve seed vigour relative to mid-May (May) seeding dates. We compared seed size, seed

Seed vigour and water relations in wheat

Annals of Applied Biology, 1990
SUMMARYThe laboratory germination (criterion radicle emergence) of seven seed lots of winter wheat cv. Slejpner was similar. However, they differed in vigour as demonstrated by differences in germination after controlled deterioration carried out at a range of seed moisture contents, at two temperatures and for different times.

STUDIES ON SEED VIGOUR IN SORGHUM

Madras Agricultural Journal, 1987
Studies made on the nature of association of different vigour tests with field emergence in sorghum (CSH 5) seeds revealed that standard germination, vigour index, germination after soaking them in sodium hydroide and ammonium chloride solutions and rate of germination correlated positively and highly significantly with field emergence.

Seed Composition, Seedling Emergence and Early Seedling Vigour of Red Kidney Bean Seed Produced at Elevated Temperature and Carbon Dioxide

Journal of Agronomy and Crop Science, 2009
Understanding the influence of growth temperature and carbon dioxide (CO2) on seed quality in terms of seed composition, subsequent seedling emergence and early seedling vigour is important under present and future climates.

What Is Seed Vigour?

Journal of New Seeds, 2000
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.

Seed and seedling vigour

1988
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 ...

Seed Viability and Vigour

1988
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 ...

​A Novel Seed Priming Technique for Enhancing Seed Vigour and Yield Potential in Marginal Vigour Seeds of Blackgram (Vigna mungo L.)

LEGUME RESEARCH - AN INTERNATIONAL JOURNAL, 2021
Background: Seed priming is controlled hydration and dehydration that results in improved seed quality and yield. However, hydration-dehydration of fresh seeds would result in soaking injury especially in legumes. The disadvantage reported in pulses can overcome through pre-conditioning of seeds which allows the seeds to slow hydration and prevent the ...
