Proper storage of peanut(Arachis hypogaea L.) seed is essential for maintaining viability to ensure adequate plant stands are achieved upon planting. Experiments conducted in Georgia from 2017 to 2018 evaluated cultivar by storage condition by sampling date effects on three peanut cultivars. The effects of varying environments, with respect to different temperatures and humidity, on peanut seed viability was evaluated when stored up to 72 d. Seed germination and vigor were assessed in petri dishes on a thermal gradient table with temperatures ranging from 10.2 to 33.2 °C and incubated for 7 d. Daily mean temperature data were used to calculate growing degree day (GDD) accumulation via thermocouples. Maximum germination rates (b0) and GDD values at 80% germination (Germ80) were quantified. Results indicated that germination and vigor varied by cultivar, storage environment, and sampling date with respect to GDDs required to reach Germ80 and maximum germination (b0). Storage environment treatments consisted of (a) 9–12 °C and 43–51% relative humidity (RH), (b) 18–27 °C and 42–54% RH, (c) 12–37 °C and 48–74% RH, and (d) 24–46 °C and 33–85% RH. Storage environments affected seed germination, where environments with large fluctuations in temperature and RH (12–37 °C, 48–74% RH and 24–46 °C, 33–85% RH) for up to 72 d resulted in decreased percentage germination (>20 points) and vigor (>5 GDDs). However, excellent seed germinationand vigor were sustained where storage temperatures were below 18 °C and RH was below 54%. Therefore, maintaining proper temperatures and RH is key to sustaining seed quality (germination and vigor) over time.

脱壳后贮藏环境对花生种子萌发及活力的影响

适当储存花生 ( Arachis hypogaea L.) 种子对于保持活力至关重要，以确保在种植时获得足够的植株。2017 年至 2018 年在乔治亚州进行的实验通过采样日期对三个花生品种的影响，按储藏条件评估了品种。当储存长达 72 天时，评估了不同环境（相对于不同温度和湿度）对花生种子活力的影响。种子萌发和活力在培养皿中在温度梯度表上评估，温度范围为 10.2 至 33.2 °C，并孵育 7 天。日平均温度数据用于通过热电偶计算生长期 (GDD) 累积。最大发芽率 ( b 0) 和 80% 发芽时的 GDD 值 (Germ80) 被量化。结果表明，就达到 Germ80 和最大发芽 (b0) 所需的 GDD 而言，发芽和活力因品种、储存环境和采样日期而异。存储环境处理包括 (a) 9–12 °C 和 43–51% 相对湿度 (RH)，(b) 18–27 °C 和 42–54% RH，(c) 12–37 °C 和 48– 74% RH，和 (d) 24–46 °C 和 33–85% RH。储存环境影响种子发芽，温度和相对湿度（12–37 °C，48–74% RH 和 24–46 °C，33–85% RH）波动较大的环境长达 72 天导致种子发芽率下降(>20 分) 和活力 (>5 GDD)。然而，在储存温度低于 18 °C 和相对湿度低于 54% 的情况下，种子仍能保持良好的发芽和活力。所以，
