Main conclusionSeed priming with gas plasma activated water results in an increased ageing resilience inEragrostis tefgrains compared to a conventional hydropriming protocol.AbstractTef（Eragrostis tef）是一种禾本科牧草，是埃塞俄比亚和厄立特里亚的主要粮食作物。尽管它在生产、消费和经济作物价值方面具有重要意义，但tef的研究不足，其生产力也很低。在本研究中，茶籽经不同引发处理以提高种子活力及幼苗表现。一个传统的水引发和一种新的添加剂引发技术与气体等离子体活化水（GPAW）已被使用和茶籽颗粒，然后进行发芽性能测定和加速老化。Tef引发提高了种子的发芽速度和活力。GPAW引发在老化后保留了种子的储存潜力，因此，提出了一种创新的环境友好型种子技术，其前景是应对多变的天气条件和最终的粮食不安全。种子技术开辟了新的可能性，以提高tef作物种植的生产力，通过育种以外的农业可持续集约化，在埃塞俄比亚实现安全和有弹性的tef粮食系统和经济增长。
Main conclusionSeed priming with gas plasma-activated water results in an increased ageing resilience inEragrostis tefgrains compared to a conventional hydropriming protocol.AbstractTef (Eragrostis tef) is a cereal grass and a major staple crop of Ethiopia and Eritrea. Despite its significant importance in terms of production, consumption, and cash crop value, tef has been understudied and its productivity is low. In this study, tef grains have undergone different priming treatments to enhance seed vigour and seedling performance. A conventional hydropriming and a novel additive priming technology with gas plasma-activated water (GPAW) have been used and tef grains were then subjected to germination performance assays and accelerated ageing. Tef priming increases the germination speed and vigour of the grains. Priming with GPAW retained the seed storage potential after ageing, therefore, presenting an innovative environmental-friendly seed technology with the prospect to address variable weather conditions and ultimately food insecurity. Seed technology opens new possibilities to increase productivity of tef crop farming to achieve a secure and resilient tef food system and economic growth in Ethiopia by sustainable intensification of agriculture beyond breeding.
