Studies on the development of the intercellular spaces in the roots and leaves of the seedlings of rice plants

[摘要] The development of lysigenic intercellular space in the roots and aboveground parts of the seedlings of rice plants "Norin No. 18" and "Kinugasawase." was comparatively studied and besides the connection betweeen the intercellular spaces in roots and those in aboveground parts was examined. The results are summarized as follows: 1) The development of intercellular spaces in roots and aboveground parts of the rice plants was evident, and difference in the mode of development according to the variety was observed. 2) The formation of intercellular spaces in the cortex of roots was more evident in the variety "Norin No. 18" than in "Kinugasawase" and the similar tendency wad observed in their leaves, too. 3) It was confirmed that intercellular spaces in roots and aboveground parts were connected eachother.
