Abstract
Abstract A plant tissue culture vessel with a substantially flat fine screening element (2) elevated above the inner bottom surface (3) of the vessel, the vessel being sterilizable, substantially sealable (by a lid, not shown) and adapted for growing plant tissue cultures supported on the surface of the screening element in optimal contact with a culture medium filling the vessel to the level of the screening element (2). The screening element has a mesh size which permits the passage of the culture medium therethrough while retaining the tissue culture on the surface thereof.
