Abstract

Background: N. wightii (Leguminosae) is valued as a cover crop and as a potential source of protein in food insecure countries. However, plantlet establishment is limited by physical dormancy. Our previous work has shown that exposure of N. wightii seeds to cryogenic temperatures is able to overcome physical dormancy.

Objective: The current study is an extension of that work where the field performance and nutritional composition of plants regenerated from N. wightii seeds was investigated.

Results: It was evident that plants regenerated from cryopreserved seeds displayed faster growth rates than those from control seeds. In addition, cryopreservation did not alter the nutritional profile of plants produced from cryo-stored seeds.

Conclusion: Collectively, the results indicate that cryopreservation serves as a suitable strategy for the preservation of seeds of N. wightii with the added benefit of also serving as a dormancy breaking mechanism upon retrieval from cryogenic temperatures. Doi.org/10.54680/fr23510110712.

新白桦种子的低温保存:一种保存、打破休眠和保存营养状况的策略。

背景:豆科植物N. wightii (Leguminosae)在粮食不安全国家被视为覆盖作物和潜在的蛋白质来源。然而，植物的建立受到物理休眠的限制。我们之前的工作已经表明，将白衣黑衣种子暴露在低温下能够克服物理休眠。目的:本研究是对羽衣甘蓝种子再生植株的田间生产性能和营养成分进行研究的延伸。结果:冷冻种子再生植株的生长速度明显快于对照种子。此外，低温保存不会改变冷冻种子所产生的植物的营养成分。结论:综上所述，低温保存是一种适合于夜蛾种子保存的策略，并且还可以作为低温恢复后休眠打破机制。Doi.org/10.54680/fr23510110712。
