Abstract

湿害発生時におけるダイズの根粒着生の意義を明らかにするために, 根粒着生系統「T 202」と根粒非着生系統「T 201」の同質遺伝子系統を転換畑で栽培し, 花芽分化期, 開花期および登熟期に8~10日間, 畦間に5~8 cmの深さに水を溜めて過湿処理を行った。葉身窒素含有率ならびに乾物生産は, 両系統ともいずれの生育段階においても過湿処理によって減少したが, その程度はT 202の方が小さかった。花芽分化期と開花期においては, 葉身窒素含有率, 乾物生産ともにT 202では処理が終わると約15日で回復したのに対し, T 201では回復しなかった。子実収量は乾物生産量の減少によって低下したが, その程度もT 202で小さかった。このような両系統の違いは, 根粒による固定窒素供給の有無によってもたらされた。すなわち, T 202は根粒が着生することによって過湿障害が軽減され, それからの回復も早められることが明らかとなった。また, 以上の結果から判断して, 根粒による固定窒素の供給は湿害を軽減するうえで重要な役割をはたしているものと推察された。
