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 ...

Maize PIMT2 repairs the damaged 3-METHYLCROTONYL COA CARBOXYLASE in mitochondria controlling seed vigor.

The Plant Journal, 2023
PROTEIN L-ISOASPARTYL O-METHYLTRANSFERASE (PIMT) regulates seed vigor by repairing damaged proteins. While capable of isoaspartyl repair in all proteins, those proteins most susceptible to isoAsp formation have not been well characterized and the ...

Soybean seed vigor discrimination by using infrared spectroscopy and machine learning algorithms.

Analytical Methods, 2020
A novel approach to distinguish soybean seed vigor based on Fourier transform infrared spectroscopy (FTIR) associated with chemometric methods is presented. Batches with high and low vigor soybean seeds were analyzed.

Seed Vigor and Vigor Testing

2001
Seeds, as reproductive units, are expected to produce plants in the field. However, farmers and seed producers have long recognized that the labeled germination often overestimates the actual field emergence of seed lots. This occurs because by definition, germination is the “emergence and development from the seed embryo of those essential structures ...

Evaluation of Vigor Tests for Sorghum Seed¹

Agronomy Journal, 1973
AbstractStandard germination tests often overestimate field performance of sorghum [Sorghum bicolor, (L.) Moench] seed. Seed from 60 seed lots were germinated following NH4CI treatment, NaOH treatment, and no treatment. Results from these tests, seed size, and tetrazolium staining were correlated with field stand establishment under four sets of ...

Vigor tests on lettuce seeds and their correlation with emergence.

Ciencia e investigación agraria, 2005
Themain objective of this study was to evaluate some of the available seed vigor tests to predict lettuce ( Lactuca sativa L.) seedling emergence. Eight lettuce seed lots were evaluated by the following laboratory vigor tests: germination (GT), accelerated ageing (AA), saturated salt accelerated aging (SSAA),conductivity (EC), and digital image ...

Grain Sorghum Field Emergence and Seed Vigor Tests

2014
Poor emergence of sorghum [(Sorghum bicolor (L) Moench] affects the stand and potential yields. The major objective of this research was to find correlations among field emergence data and laboratory seed vigor tests. Thirty-two and 30 hybrids of sorghum were planted at three Virginia locations in 1995 and 1996, respectively.
