The main objective of this study was to elucidate the roles of silicon (Si) in enhancing tolerance to freezing stress (−5 °C) in two contrasting wheat ( Triticum aestivum L.) cultivars: i.e. cv. Yangmai No. 5, a freezing-susceptible cultivar and cv. Linmai No. 2, a freezing-tolerant cultivar. Shoot...
