Two winter wheat (Tritium aestivum L.) cultivars, Linmai No.2 (resistant) and Yangmai No.5 (susceptible), were grown hydroponically to investigate the effects of exogenous silicon (Si) on photosynthetic and physiological parameters, chlorophyll content, active oxygen radicals, antioxidative defenses, and osmotic adjustment in cold-stressed wheat seedlings. The main results were presented as follows:
Exogenous Si increased shoot Si content of both wheat cultivars with Si content being higher in Li...
