Abstract: In this study, 15 oat varieties were used to investigated the effects of different seed moisture content [12% (T1), 14% (T2), and 16% (T3)] and storage methods (conventional and hermetic storage) on the germination characteristics. The results revealed that there were significant genotypic differences (P<0.05) in response to moisture stress among the varieties, which were further influenced by storage duration and method. For example, ‘Baiyan 7’ exhibited the best performance during the initial germination stage at 16% moisture treatment (T3), whereas varieties such as ‘Qinghai Sweet Oat’ showed higher germination rates under low moisture conditions (T1). In addition, storage methods significantly altered moisture sensitivity of varieties: conventional storage increased the suitable moisture threshold to T3 for certain varieties, while hermetic storage reduced the moisture requirement of most varieties. Embryo development analysis revealed that distinct patterns in radicle and plumule biomass responses to moisture levels among varieties. Hermetic storage induced a shift from linear to peak-curve responses in these traits. Differential sensitivity to moisture between radicles and plumules was also observed, indicating genotype-specific resource allocation strategies. Hermetic storage had a highly significant effect (P<0.01) on oat seed germination characteristics. Based on TOPSIS comprehensive evaluation, ‘Qingyan 1’ was identified as the best stablity. Furthermore, strong correlations were observed between embryo indicators and germination parameters, suggesting that they could be used as a reliable predictor of seed vigor.

摘要: 本研究以15个燕麦品种为材料,探讨不同种子含水量[12%(T1)、14%(T2)、16%(T3)]与贮藏方式(常规贮藏、密闭贮藏)对发芽特性的影响。结果表明,品种对水分胁迫的响应存在显著基因型差异(P<0.05),且该响应受贮藏时间和方式的显著调控(‘白燕7号’在16%含水量下萌发初期表现最佳,而‘青海甜燕麦’等品种在低水分(T1)条件下发芽率更高)。此外,贮藏方式显著改变品种水分敏感性:常规贮藏使部分品种适宜含水量阈值升高至T3,密闭贮藏则使多数品种对水分的需求降低。胚胎发育分析显示,不同品种胚根与胚芽生物量对水分响应模式各异,密闭贮藏可诱导线性响应转为峰值曲线。胚根与胚芽对水分敏感性存在器官差异,表明资源分配策略具基因型特异性,同时,密闭贮藏对燕麦种子发芽特性产生极显著影响(P<0.01)。TOPSIS综合评价表明‘青燕1号’稳定性最优。此外,胚胎指标与萌发参数高度相关,表明其可作为种子活力评估的可靠依据。
