Relationship of Seed Vigor to Crop Yield: A Review

Seed viability and vigor directly affect the performance of seeds planted to regenerate the crop. Although seed quality can influence many aspects of performance (e.g., total emergence, rate of emergence), the objective of this review was to examine the relationship of seed vigor to one aspect of performance : crop yield. Reductions in yield can be indirectly related to low seed vigor if plant populations are below a critical level. Thus, we have reported only on the direct effects of seed vigor on yield in the absence of population differences (...)
