ISTA Workshop on Advanced Seed Vigour Testing Add event to my calendar International Seed Testing Association (ISTA)* Bangalore, India The workshop will be focused on two of the ISTA validated tests, the Radicle Emergence test and the Conductivity test. The workshop will be made up of practi...
Seed vigour is an important aspect of seed quality. It is a quantitative trait which is responsible for overall seed performance in terms of rate and uniformity of seed germination, seedling growth, emergence ability under unfavourable environments and post storage performance. Seed vigour is controlle...
however, compare to ethrel GA3 only given better result. During seed priming the process of hydration initiates the earliest physiological stages of germination and perhaps physiological repair of membranes and organelles damaged during seed storage resulting in more rapid and uniform seedling emergence....
Correlation analysis revealed that volatile aldehyde was the optimal index for seed vigour assessment of super sweet corn and dehydrogenase activity was the optimal for sugar‐enhanced sweet corn. On the basis of correlation analysis, regression equations were established for predicting field emergence ...
VigorindexII=Germination%×drybiomass Statistical analysis Each treatment consists of three replicates. The greenhouse experiment was organized using completely randomized designs (CRD). Utilizing SPSS Software version 9, the data were subjected to an ANOVA, and the means of treatments were compared usin...

Early vigour would also be important for drilled crops. There is a large genotypic variation for seedling emergence from deep soil. Lee et al. (2017) found this variation to be associated with mesocotyl length for seed sown at 5 cm depth. Using 57 rice genotypes, they found indica genotypes...
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 developme...
The first three axes of the principal component analysis across the two seasons captured 86.34% of the total variation among the entries and identified seedling vigour index-I, seedling vigour index-II, speed of germination index, percentage germination, seedling establishment, emergence percentage and...
Germination, seed emergence and subsequent seedling vigour are critical for good establishment and healthy early plant growth. In cotton production systems, poor germination and emergence and low early seedling vigour can lead to reductions in yield1. In addition, the presence of pathogens, water ...
