1,3-Diphenylurea

一种细胞分裂素；在1-16mg/L的培养基中可增加烟草植物组织的鲜重；在32µM和100µM浓度下促进菜豆（P.lunatus）愈伤组织的生长；在首次传代培养时外源施用，可在32µM和100µM浓度下诱导菜豆组织在第二次传代培养中获得细胞分裂素自主性。A cytokinin; increases fresh weight of tobacco plant tissue from 1-16 mg/L in growth media; increases the growth of cultured P. lunatus callus tissue at 32 and 100 µM; exogenous application during first-passage culture induces second-passage cytokinin autonomy in cultured P. lunatus tissue at 32 and 100 µM.分子式C13H12N2O分子量212.3O=C(NC1=CC=CC=C1)NC2=CC=CC=C2
