STORAGE OF YOUNG RICE PLANT AND RAISING SEEDLING OF STORED YOUNG RICE PLANT

摘要

PURPOSE: To provide a liquid for the storage of a young rice plant, composed of an inorganic salt, having an osmotic pressure adjusted to a specific level and effective for the long-term storage of a young rice plant redifferentiated by a tissue-culture technique to obtain a seedling suitable for the transplantation to a paddy field. ;CONSTITUTION: This storage liquid is composed of an inorganic salt and has an osmotic pressure adjusted to 5-120mOSMOL/kg. The storage liquid is preferably a culture medium residue left after the redifferentiation treatment of rice plant. The liquid is preferably incorporated with a plant growth regulator having a spindly growth suppressing action such as ancymidol. In the case of storing a young rice plant, it is preferable to culture the plant in an inorganic salt liquid medium free from sugar and containing ancymidol and an agent having root-taking and growthpromoting actions under light irradiation and aeration with air enriched with carbon dioxide gas and store the cultured plant in the storage liquid at 15-20°C, a photoperiod of 3-24hr and an illumination intensity of 200-30,000Lux.;COPYRIGHT: (C)1996,JPO
