Analysis of seed germination attributes and kinetics of Polygonatum sibiricum Red. through metabolomics and transcriptomics

Polygonatum sibiricum Red. (P. sibiricum) seeds exhibit strong dormancy, which prolongs germination period, reduces germination rate, and thus hinders its production. Research on breaking seed dormancy via optimized sand storage and clarifying germination-related mechanisms is insufficient. This study focused on optimizing sand storage conditions of P. sibiricum seeds and analyzing their biological traits, enzyme gene expressions, and metabolic changes to elucidate germination kinetics.
