In this present study, seed vigor was tested after different storage durations (0, 60, 120, 180 days; maximum 420 days) in air-conditioning cabinets set to various temperatures (4, 10, 20 °C) and free-temperature at room condition. After seven days for each of the storage durations, germination rate (GR), mean germination time (MGT), germination speed (GS), seed vigor index (SVI), shoot and root length (SL, RL), shoot and root dry weight (SDW, RDW), root number (RN), electrical conductivity (EC) and pH for all seed lots were recorded. The average GR at room temperature storage decreased from 86% recorded on the 60th day, to 59% by the end of the 420th day, while germination rate was still around 70% with the seeds stored at 4 °C. The decrease in GS was recorded after the 300th day till the end of 420 days of storage (ranging between 9.8 and 9.4 seed day−1). The lowest SVI was 7.9 at the beginning of storage (day 0) and increased gradually within 60 days of storage for all temperatures tested. Irrespective of storage duration, the SL and RN showed the highest overall mean of 10.7 cm and 4.8 root for the seeds stored at 4 °C. EC sharply decreased overall to a mean of 18.9 μScm−1 g−1 for all temperatures within the first 60 days of storage. The highest correlation (r = 0.937) was determined between GS and MGT. This study provides a new insight to the farmers for better understanding that concerns practical implications of einkorn farming as follows: storage at 4 °C is best way of the maintanence of highest seed vigor. For the storage duration regardless of the temperatures, it can be kept minimum 60 days, since the seed deterioration can be effective after 180 days of storage depending on storage temperature.

在上单粒小麦种子的各种生理参数不同温度下存储的持续时间的影响(小麦monucocum L.)发芽

在本研究中,在设置为各种温度(4、10、20°C)和自由温度的空调柜中,在不同的储存时间(0、60、120、180 天;最长 420 天)后测试了种子活力。房间条件。每个储存期 7 天后,发芽率 (GR)、平均发芽时间 (MGT)、发芽速度 (GS)、种子活力指数 (SVI)、枝条和根长 (SL、RL)、枝条和根干记录所有种子批次的重量(SDW、RDW)、根数(RN)、电导率(EC)和 pH 值。室温储存的平均 GR 从第 60 天记录的 86% 下降到第 420 天结束时的 59%,而种子在 4°C 下储存时发芽率仍约为 70%。在第 300 天后到 420 天储存结束(范围在 9.8 和 9.-1 )。最低 SVI 在储存开始时(第 0 天)为 7.9,并在所有测试温度下在储存 60 天内逐渐增加。无论储存时间长短,对于储存在 4°C 下的种子,SL 和 RN 显示出最高的总体平均值为 10.7 厘米和 4.8 根。EC 总体急剧下降至平均值 18.9 μScm -1 g -1适用于储存前 60 天内的所有温度。GS 和 MGT 之间的相关性最高 (r = 0.937)。这项研究为农民提供了新的见解,以更好地了解单粒玉米种植的实际意义,如下所示:在 4 °C 下储存是保持最高种子活力的最佳方式。不论温度如何,储存时间至少可以保持 60 天,因为根据储存温度,种子在储存 180 天后会变质。
