Water constitutes nearly 100% of the volume and 95% of the mass of gelled plant tissue culture media. Even so, plant growth and development responses observed to occur with relatively small changes in gelling agent concentration (0.1% of media total mass) have been attributed to changes in media water availability. Measurements with three alternative direct techniques, specific for measuring physiochemical water availability indicated the effects of a change of this magnitude in gelling agent… CONTINUE READING
