GABA-mediated modulation of drought stress tolerance and seed morphology during flax (Linum usitatissimum L.) germination via image analysis.

ABSTRACT: Seed coat color, a trait exhibiting significant phenotypic variation, has been reported in previous studies to influence key germination parameters, including germination percentage, germination rate, and mean germination time. Looking into these relationships can help us identify plant varieties that better withstand both living threats and environmental challenges, which would make breeding programs more effective and focused. The objectives of this study were to evaluate the drought tolerance of 20 flax varieties at the germination stage, investigate the effects of gamma-aminobutyric acid (GABA) on seed germination performance under drought stress conditions, and explore potential associations between seed coat color and germination parameters under both stressed and non-stressed condit
