Abstract :ウコンの栽培技術を検討する一環として, 遮光処理がウコンの生育・収量に及ぼす影響について調べた。1) 自然光に対する受光量が100∿57%の条件では, 遮光度が増加するにつれ草丈及び主茎生葉数は増加し, 分げつ数は減少した。2) 地上部乾物重, 根茎乾物重および根乾物重は, いずれも遮光によって著しく増加した。自然光に対する受光量が78∿57%の条件では, 遮光の強弱による差は認められなかった。3) 遮光によって根茎乾物率は増加し, 根茎への同化産物の蓄積が促進されたものと思われた。4) 以上のように, 遮光による生育の促進, 根茎収量の増加が認められたことから, ウコンの栽培に被陰は有効であると考えられた。
Effects of shading on the growth characteristics and yield of Turmeric were investigated in the experiment. The following results were obtained. 1) Plant length and number of leaves per main stem were increased with the increased shading levels. On the contrary, number of tillers decreased with the increased shading levels. 2) Top dry matter weight, rhizome dry matter weight and root dry matter weight were increased considerably under shading condition from 78 to 57% relative light intensity. There were no significant difference of these dry matter production within these shading levels. 3) Percent dry matter of rhizome increased by shading, which might be facilitate the storage of assimilation products. 4) It was observed that Turmeric growth and yield were promoted under shading. It was suggested from the experimental result that Turmeric might be possible to cultivate under the shading condition for increased yield.
