| 摘 要： | 在人工水分胁迫条件下,通过对12份云南西双版纳割手密82-114(简称云割82-114)血缘F2代丙二醛含量(MDA)、相对电导率(PMP)、株高伤害率及+2叶相对重量测定,并采用隶属函数法进行综合分析.结果表明,①09-P58、09-P88、08-821、09-P54、08-719共5份材料抗旱性较强,08-721、09 -P42、09-P68共3份材料抗旱性中等,09-P75、09-P78、09-P109、09-P60共4份材料抗旱性较弱.②12份材料的抗寒性均超过对照新台糖ROC22.可为甘蔗抗旱品种选育提供亲本材料和依据.

| Abstract: | The malondiadehyde content(MDA),leaf plasma membrane permeability(PMP),plant height and leaf weight of 12 descendants F2 of Saccharum spotaneum 82-114 in Yunnan were measured under drought stress.Comprehensive analyzing evaluation by the method of subjection function,the results showed that(i) the drought resistance of 09-P58,09-P88,08-821,09-P54 and 08-719 were stronger than that of others,and the drought resistance of 08-721,09-P42 and 09-P68 were medium;(ii) the drought resistance of 12 descendants were ... |
