Recently detected but unidentified cytokinin activity in crown gall tumor tissue from Vinca rosea L. grown on media containing sources of reduced nitrogen has now been attributed to two adenine-type cytokinins. These compounds are glucopyranosyl derivatives of zeatin and ribosylzeatin. The substitution in each case is on the isopentenyl chain of the parent compound. Neither of these compounds had activity in the soybean callus bioassay at concentrations lower than 1 nm whereas zeatin had activity at 0.1 nm.
最近在含有还原氮源的培养基上生长的长春花（Vinca rosea L.）冠瘿组织中检测到但尚未鉴定的细胞分裂素活性，现在已归因于两种腺嘌呤型细胞分裂素。这些化合物是玉米素和核糖玉米素的吡喃葡萄糖苷衍生物。在每种情况下，取代都发生在母体化合物的异戊烯基链上。在大豆愈伤组织生物测定中，这两种化合物在低于 1nm 的浓度下均没有活性，而玉米素在 0.1nm 时有活性。
