In vitro chromosome doubling of nucellar embryos was investigated in Meiwa kumquat (Fortunella crassifolia Swingle). Nucellar embryos were aseptically treated with two antimitotic agents, colchicine a...
秋水仙碱诱发玉米变异特性的追踪研究Study on Variation Specificity of Maize Induced by Colchicine
秋水仙碱 玉米 变异特性
2008/1/16
摘要对秋水仙碱诱发产生的5种玉米变异材料，在自交2年后,进行了变异特性的追踪检测。结果显示：不同来源的玉米变异材料，其发芽势提高了3%～46%，玉米根尖分生区细胞直径减小了6%～15%，同时分生区细胞核直径则增大了5%～18%，玉米根尖分生区细胞染色体数目变异率达25.25%～38.55%，且染色体数目变异范围主要在10～30条之间。其中，供试玉米No.1和No.16根尖细胞染色体条数趋向大于20...
