中文摘要：

以花生为材料,结合根长实验、苏木精染色和根尖铝含量测定等方法,筛选出耐铝品种99-1507和铝敏感品种中花2号。99-1507半抑制浓度大于100μmol/L,中花2号约为60μmol/L。在铝诱导产生细胞程序性死亡后,经苏木精-伊红复染后,花生根尖细胞表现出细胞核致密,核型发生变化,呈新月状或椭圆状,出现类似凋亡小体。

英文摘要：

Peanut cultivars 99-1507 （Al-resistant） and Zhonghua No.2 （Al-sensitive） were selected for root elongation experiment, hematoxylin dyeing and root tips Al content detection. After the appearance of PCD induced by Al treatment, peanut root tip cells showed some changes in their morphological characteristics, such as cytoplasmic shrinkage, nuclear condensation, crescent and ellipsoid nucleolus, and the emergence of similar apoptotic bodies after Hematoxylin-Eosin （HE） dyeing.
