Effect of water stress on cell division and cell-division-cycle 2-like cell-cycle kinase activity in wheat leaves

abstract：:The activities of the free base and ribonucleoside forms of cytokinins bearing saturated and unsaturated N(6)-isoprenoid side chains have been examined in callus cultures derived from Phaseolus vulgaris cv. Great Northern, P. lunatus cv. Kingston, and the interspecific hybrid Great Northern x Kingston. In callus of cv...
