In order to optimumly control the growth of plant tissue in vessels, physical coditions in gel medium is re quired to be kept in optimum conditions. Especially, solute and/or water movements through gel medium could effect growth condition in plant tissue culture vessels. In this report, physical parameters for these movements are measured. The results are summarized as follows :1. Matric potential in gel medium is over-5cm(aq.)and negligible as a driving force for water movement.2. Overburden weight on gel me dium is directly changed to overburden potential and increase water potential in the medium.3. Hydraulic conductivity through gel medium depends highly on gel concentration and changes markedly around the gel concentration for normal use.4. Morechlar diffusion coeficients of solutes in gel medium can be regarded to have the same values in water.5. Solute movement by molecular diffusion is more have influencial than that by mass flow with water.

为了最好地控制植物组织在容器中的生长，凝胶介质中的物理条件需要保持在最佳条件下。尤其是凝胶介质中的溶质和/或水分运动会影响植物组织培养容器的生长状况。在本报告中，测量了这些运动的物理参数。主要研究结果如下：1.凝胶介质中的基质电势大于-5 cm(Aq)，对水运动的驱动力可以忽略不计。冻胶介质上覆岩层重量直接转化为上覆岩层水势，增加了介质中的水势。凝胶介质的导水率高度依赖于凝胶浓度，正常使用时在凝胶浓度附近有明显的变化。溶质在凝胶介质中的较大扩散系数在水中可视为具有相同的值。分子扩散对溶质运动的影响比带水的质量流动更大。
