    • PURPOSE:To obtain a new carboxymethyl cellulase unique to rice and useful as an agent for the production of oligosaccharide in the tissue culture of rice or an agent for forming protoplast of rice. CONSTITUTION:The carboxymethyl cellulase of rice has the following physical and chemical properties. (1) Substrate specificity, decomposes beta-1,4-glucan chain into endo-type and decomposes carboxymethyl cellulose, beta-1,3-1,4-glucan, beta-D- glucan, etc.; (2) molecular weight, 24kD measured by gel permeation with Sephacryl S-200; (3) optimum pH, 5.0-6.0 in the case of treating at 30 deg.C for 15-30min using carboxymethyl cellulose as a substrate; (4) stable pH, 6.0-7.0 in the case of leaving standing in sodium phosphate (10mM, 1mM DDT) for 1 week; (5) optimum temperature, 30-35 deg.C in the case of treating at pH-5.5 for 15-30min using carboxymethyl cellulose as a substrate. It can be prepared by culturing a tissue of rice on an auxin-containing medium and collecting from a section of the cultured tissue.

    • PROBLEM TO BE SOLVED: To provide a germination treatment method that can arbitrarily control the dormant period of the seed of water plant and can rapidly germinate the seed according to need, and the storage vessel for receiving the seed that has become efficiently germinative, and a method for planting the seed of water plant.
      SOLUTION: In this method for storage and germination treatment of seeds of water plant, the seeds of water plant are collected, treated, for example, at 4°C, the first temperature, for example, at least more than one month in water to maintain the dormant condition, then the treated seeds are kept at 20°C, the second temperature condition, thereby the seeds are made germinative. In the method for planting seeds of water plant, the seeds made germinative are scattered in a storage vessel in which water is stored, then the storage vessel is set in the transplanting area together with the rough woven fabric constituting the storage vessel.
