High-performance liquid chromatography, immunochromatography, and radioimmunoassay were used to identify cytokinin-like bases and glycosides in xylem sap of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). Isopentenyladenosine-type (isopentenyladenine and isopentenyladenosine) and zeatin-riboside type (zeatin, zeatin riboside, and dihydrozeatin riboside) cytokinins were detected during springtime. A glucosyl conjugate of zeatin riboside was also present in small amounts. Levels of cytokinin-like compounds varied throughout the spring but were generally highest in late April to early May.
采用高效液相色谱法、免疫色谱法和放射免疫分析法对花旗松（Pseudotsuga menziesii (Mirb.) Franco）木质部汁液中的细胞分裂素类碱基和糖苷进行鉴定。在春季检测到了异戊烯基腺苷型（异戊烯基腺嘌呤和异戊烯基腺苷）和玉米素核糖苷型（玉米素、玉米素核糖苷和二氢玉米素核糖苷）细胞分裂素。玉米素核糖苷的葡萄糖基共轭物也有少量存在。细胞分裂素类化合物的水平在整个春季有所变化，但通常在4月下旬至5月初最高。
