【摘要】 把具有不同抗旱程度的甘蔗品种种植于抗旱试验池中，在正常水分供应或干旱胁迫条件下测定一些与抗旱性有密切关系的指标。结果表明，株高伤害率可作为甘蔗抗旱性直接鉴定指标。自然水分亏缺与细胞耐热性两项指标结合起来可较全面地评价甘蔗的抗旱性，是较好的间接鉴定指标。更多还原

【Abstract】 Sugarcane varieties with diffderent degree of drought resistance were grown on a ’pool for drought-resistance trial- Some indexes which related to droughtresistance were determined under normal water or drought stress c0nditions- Theresults indicated that injury ratio of plant height can be used as the direct index for identifying drought resistance of sugarcane varieties,and they were good indirect inderes when both plant water deficit and cell membrance thermosta-bility were used simultaneously as a method for evaluating drought resistance of sugarcane varieties.更多还原
