根输水机理研究进展

概述了从根的结构出发开展根运输水分机理的研究进展 ,包括输水阻力的分布、水孔蛋白和根的复合运输模型等 ,并就其可能的生理意义加以评述。

From the point of view that root structure determines its functions, the mechanism is proposed for water transport in root at both tissue and membrane levels. This paper presented a review of the mechanism of water transport in root including the distribution of hydraulic resistance to water transport, aquaporin and composite transport model of root, and their possible physiological significance was also discussed.
