Investigating the intracellular water dynamics within leaves will clarify plant responses to different water conditions and provide a theoretical basis for enhancing water-use efficiency. Detached leaves of Chinese flowering cabbage (Brassica campestris L. ssp. chinensis var. utilis Tsen et Lee) and broccoli (Brassica oleracea L. var. italica Plenck) were used as experimental materials in this study. Electrophysiological parameters of the leaves under saturated and non-saturated conditions were measured, and the intracellular water, nutrient, and energy related indices were calculated according to Nernst equation. The acceleration (a) reflecting the change rate of water transport rate in cel... More >
