摘要
以7个抗旱力不同的水稻和范远缘杂交后品系为试材,进行抗旱测定,对其种子、幼苗、成株进行水分胁迫及叶片气孔观察发现,寒九和远4437是真正的抗旱类型,而其余6个品系均同敏感抗旱类型。
Seven hybrid progenies with different drought resistance,from distantly hybridized be-tween Oryza sativa and Zizania caducifera,were used to determine drought resistance in thisexperiment.Through studying water stress of their seeds,seedings and platns,and observingtheir leaf stroma,the result indicated that Hanjiu and Yuan 4437 are real drought-resistant culti-vars,and the other six ones are sensitive to drought resistance.
