Abstract
The diphenylurea derivative thidiazuron induces a variety of cytokinin responses. Levels above 5 x 10(-9) molar and 4 x 10(-7) molar stimulate maximum soybean callus growth and radish cotyledon expansion, respectively. A wider range of dose response related effects follows thidiazuron induced tobacco plant regeneration. Analysis of soybean callus extracts strongly suggests that thidiazuron treatment creates an accumulation and/or synthesis of purine cytokinins, able to induce the growth, expansion and regeneration, mentioned above.
摘要
二苯脲衍生物噻二唑隆诱导各种细胞分裂素反应。浓度高于 5 x 10(-9)摩尔和 4 x 10(-7)摩尔时，分别刺激大豆愈伤组织生长和萝卜子叶扩张达到最大值。噻二唑隆诱导烟草植物再生后，还会出现更广泛的剂量反应相关效应。对大豆愈伤组织提取物的分析强烈表明，噻二唑隆处理会导致嘌呤细胞分裂素的积累和/或合成，从而诱导上述生长、扩张和再生。
