摘要 许多涉及 G. klotzschianum 的棉属种间杂种会导致胚胎或幼苗死亡。在组织学上，致死症状的特征是在胚胎致死物中受精后10-15天出现坏死细胞和肿瘤，在幼苗致死物中出现在第一真叶阶段。幼苗致死细胞坏死的超微结构研究表明，第一个亚细胞异常是线粒体内膜和嵴的变性。在其他细胞器显示结构畸变的证据之前，线粒体变性基本上已经完成。芸苔属（Kehr，1965）、曼陀罗属的种间杂种中的遗传肿瘤已被描述
A B S T R A C T Many Gossypium interspecific hybrids that involve G. klotzschianum result in either embryo or seedling lethals. Histologically, lethal symptoms are characterized by necrotic cells and tumors that appear 10-15 days after fertilization in the embryo lethals and at the first trueleaf stage in the seedling lethals. Ultrastructural studies of cell necrosis in seedling lethals show that the first subcellular abnormality is the degeneration of the inner membrane and cristae of the mitochondria. Mitochondrial degeneration is essentially complete before other organelles show evidence of structural aberrations. GENETIC TUMORS in interspecific hybrids have been described for Brassica (Kehr, 1965), Datura
