Abstract:In order to investigate the variation patterns in seed traits and germinationcharacteristics of different Cerasus dielsiana germplasms, phenotypic traits and germination characteristics of C. dielsiana seeds was measured,the coefficient of variation for each indicator,and conducted correlation and principal component analyses in relation to geographical factors of the germplasm resources were analyzed. The results showed that there were highly significant diferences in seed length,seed width,seed thickness,length-to-width ratio, length-to-thickness ratio,width-to-thickness ratio,and hundred-seed weight among diferent C.dielsiana germplasms.Hundred-seed weight was the primary trait contributing to seed variation,with a coefficient of variation of 24.35% . There were also highly significant differences in seed germination characteristics among different germplasms,with wyO5 exhibiting the highest germination rate and germination potential at 97.33% and 78.67% , respectively. Geographical factors showed highly significant or significant correlations with seed traits,influencing both phenotypic traits and germination characteristics. Altitude was highly significantly positively correlated with hundred-seed weight,seed length,and germination rate,highly significantly negatively correlated with water absorption rate,and significantly positively correlated with germination potential and seed width. Based on the comprehensive scores from principal component analysis,the wy04, wy05,and wyO8 germplasms demonstrated superior seed traits and germination performance,making them the preferred varieties for introduction and cultivation.
