Abstract

At least seven cytokinins have been detected in mature leaves of Populus x robusta Schneid after chromatography on Sephadex LH-20. Two of these have similar elution volumes to zeatin and zeatin riboside. A third appears to be a cytokinin glucoside. A fourth is a new, unidentified cytokinin, susceptible to mild oxidation, and yielding two cytokinin active products after acid hydrolysis. This cytokinin complex has been found in fully expanded leaves, a tissue in which cell division is completed.

摘要

用 Sephadex LH-20 柱层析法分析，在美洲黑杨成熟叶片中至少发现了七种细胞分裂素。其中两种的洗脱体积与玉米素和玉米素核苷相似。第三种似乎是细胞分裂素葡萄糖苷。第四种是一种新的、未鉴定的细胞分裂素，易被温和氧化，在酸水解后生成两种具有细胞分裂素活性的产物。这种细胞分裂素复合物存在于完全展开的叶片中，而细胞分裂在该组织中已经完成。
