Low soil temperature causes delayed and unsynchronized germination, emergence, and seedling growth, which increases the probability of seedling diseases and weed infestation during stand establishment of sugar beet. In this study, different seed priming methods (control, hydration, aerated hydration, preconditioning, GA₃, KNO₃, and kinetin) were examined to promote the germination, emergence, and seedling growth performance of sugar beet seeds under low temperatures (10 °C and 18 °C) and optimum (25 °C) conditions. Results showed that seed treatments gave higher germination, emergence, and seedling length along with shorter mean time to germination and emergence than unprimed seeds at low and optimum temperatures. However, a suitable seed treatment at low and optimum temperature was different. Preconditioning gave better results than the control seeds, while it was not superior to other seeds treatments. At 10 °C, emergence percentage increased from 37.0% in unprimed seeds to 99.5% in seeds treated with 1% of KNO₃. The lower temperature resulted in delaying the mean time to germination and emergence. Aerated hydration was found to be most suitable method for enhancement of germination and seedling growth at all temperatures. It was concluded that 8–16 h of hydration with aeration or 1% of KNO₃ should be recommended for enhancement of emergence and seedling growth of sugar beet under low temperature compared to other treatments.

较低的土壤温度导致延迟和不同步的发芽，出苗和幼苗生长，这增加了甜菜林分立过程中幼苗疾病和杂草侵扰的可能性。在这项研究中，不同的种子引发方法（控制，水合，充气水合，预处理，GA ₃，KNO ₃（和Kinetin）在低温（10°C和18°C）和最佳（25°C）条件下可促进甜菜种子的发芽，出苗和幼苗生长。结果表明，在低温和最佳温度下，种子处理比未处理的种子具有更高的发芽，出苗和苗长，并且平均发芽和出苗时间更短。但是，在低温和最佳温度下进行合适的种子处理是不同的。预处理比对照种子提供了更好的结果，但并不优于其他种子处理。在10°C时，出苗率从未涂底漆的种子中的37.0％增加到用1％KNO ₃处理的种子中的99.5％。。较低的温度导致延迟发芽和出苗的平均时间。发现充气水合是在所有温度下增强发芽和幼苗生长的最合适方法。结论是，与其他处理相比，应建议在低温下进行8-16小时的水合或1％的KNO ₃水化，以提高甜菜的出苗率和幼苗生长。
