The Influence of Carbohydrate Status and Low Temperature on the Respiratory Metabolism of Mitochondria from Etiolated Leaves of Winter Wheat
The separate and combined effect of sucrose (12%, 7 days) and low temperature (2 °С, 7 days) on the growth of plants, the content of carbohydrates in the leaves and oxidative activity of mitochondria isolated from them has been studied on the etiolated plants of winter wheat (Triticum aestivum L.)....
