Seed Vigor and Vigor Tests

1999
Seeds, as reproductive units, are expected to produce plants in the field. However, farmers and seed producers have long recognized that the labeled percent germination often overestimates the actual field emergence of seed lots. This observation is attributed to the objective of a standard germination test which states that germination is the ...

Seed Vigor Testing

Journal of New Seeds, 2000
Over the years, many seed vigor tests have been developed and evaluated. A brief outline of some of the most commonly used tests is supplied.

Understanding the molecular pathways associated with seed vigor

Plant Physiology and Biochemistry, 2012
Farmers and growers are constantly looking for high quality seeds able to ensure uniform field establishment and increased production. Seed priming is used to induce pre-germinative metabolism and then enhance germination efficiency and crop yields.

Effect of Seed Priming on Seed Dormancy and Vigor

2019
Seed dormancy is a prerequisite for preservation and cultivation of crops. The genetic characteristics of seeds and external environmental conditions combinedly influence the seed vigority. Therefore, seed dormancy and vigor can modify the growth, development, and yield capacity of both agronomic and horticultural crops.

Corn Seed Germination and Vigor Following Freezing during Seed Development

Crop Science, 2006
The potential for an early autumn frost to reduce corn (Zea mays L.) seed quality is a concern for seed producers. This study evaluated the effect of freezing rate, freezing temperature (−6, −11°C) and duration (4, 6 h), ear attachment, and endosperm composition on seed germination and vigor (accelerated aging [AA] and cold test) during seed ...

Combining ability of seed vigor and seed yield in soybean

Euphytica, 2000
Studies have shown no consensus in relationships between seed yield and vigor in soybean [Glycine max (L.) Merrill]. The lack of information regarding the inheritance of seed vigor prompted this study to determine the types of gene action and combining ability estimates for seed vigor and its related traits.

Protein Damage and Repair Controlling Seed Vigor and Longevity

2011
The formation of abnormal isoaspartyl residues derived from aspartyl or asparaginyl residues is a major source of spontaneous protein misfolding in cells. The repair enzyme protein L: -isoaspartyl methyltransferase (PIMT) counteracts such damage by catalyzing the conversion of abnormal isoaspartyl residues to their normal aspartyl forms.

Smoke–water treatment of seeds, an ancient technique for increasing seed vigor

Protoplasma
Germination is an essential phenomenon in the life cycle of plants, and a variety of external and internal factors influence it. Fire and the produced smoke have been vital environmental stimulants for the germination of seeds in many plant species, like Leucospermum cordifolium and Serruria florida.

[Effects of seed priming on vigor of Prunella vulgaris seeds].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2009
To select an effective way to enhance vigor of Prunella vulgaris seeds.Three population seeds were treated at the 20 degrees C and dark enviroment.Priming with 20% - 30% PEG and 200 - 400 mg x L(-1) GA3 could enhance seeds germination and vigor. Germination percentage of three population seeds treated with 0. 6% - 3.0% NaCl reduced, but they started to

Determination of seed vigor of the pea

2013
Seed producers regularly control seed before the distribution. Some of those methods are standard (standard germination – SG, germination energy – GE, 1000 grain mass) but some which would show reaction of the seed on unfavorable conditions in the field are not regular (cold test – CT, elctrical conductivity – EC).
