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 ...

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 ...

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 ...

Cellular substance exudation and seed vigour
Journal of Northeast Forestry University, 1992In this paper, seeds ofpinus koraiensis which has a characteristic of deep dormancy were selected as an experiment material, and the relation of cellular substance exudation to seed vigour is discussed based on the dormant state, the different measuring parts and the imbibed state of seeds before testing, as well as on the respiration of embryo and ...

STUDIES ON SEED VIGOUR IN SORGHUM
Madras Agricultural Journal, 1987Studies 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.

Effect of seeding date on canola seed quality and seed vigour
Canadian Journal of Plant Science, 2004Seedling 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, 1990SUMMARYThe 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.

Barley seed vigour and mechanical weed control
Weed Research, 2000Two field experiments investigated the influences of crop seed vigour on the effect of weed harrowing and crop:weed interactions in spring barley. Artificially reduced seed vigour, which was similar to the variation within commercial seed lots, caused a reduction in germination rate, delayed time of emergence and, consequently, caused reduced ...

Seed vigour in Iranian wheat seeds exposed to cold condition.
Mededelingen (Rijksuniversiteit te Gent. Fakulteit van de Landbouwkundige en Toegepaste Biologische Wetenschappen), 2005Cold stress occurring in the seedbed of winter wheat at the end of autumn results in reduced emergence, even of undeteriorated seed lots (which have not been subjected to a long period of storage and have not been kept in bad storage conditions). The purpose of the present study was to determine the ability of different wheat cultivars at emerging at ...

EVALUATION OF SEED VIGOUR TESTS IN BAJRA
Madras Agricultural Journal, 1987Correlations were worked out to find out the inter-relationship among the vigour toats. The standard germination test was positively and significantly correlated with the vigour tests viz. field emergence, shoot-length, root-length, dry-matter production. vigour index germination energy, brick-grit test and ammonium chloride soak test.
