摘要

1. Rice seedlings were grown under various levels of phosphate fertilizing in upland seed-bed. One of the important characters of upland seedlings, high level of starch accumulation at transplanting time, was strengthened by an adequate assimilation of phosphate. Such seedlings, when transplanted in the field, surpassed the others in rooting, growing, and incidentally, yielding abilities. For the adaptation to such bad environments as low temperature or less light intensity, seedlings were needed to reserve a little higher phosphate level. 2. Rice seeds were soaked in phosphate solution of various concentration, and also ionized phosphate solution made by electro-osmosis. Positive effects were obtained on the growth of seedlings, especially, root development by the both treatments. As the former, 0.1∼0.05 molar solutions were most effectual. As the latter, there were no significant differences between ionic values of phosphate of sodium salts ionized, and co-existence with such anions as silicate or molybdate did not increase the effect of phosphate ion. Agar coating of seed with phosphate also promoted the rooting ability of young seedlings.
