Cytokinins

These are plant hormones that encourage cell division, especially at the tip ends of shoots and roots (the apical meristems). Improved root growth can lead to improve nutrient and water uptake. Cytokinins encourage lateral growth, helping to improve sward density, and can also impact on photosynthesis within a leaf by maintaining greenness of leaf thereby delaying the leaf ageing process. They also encourage seed germination, as well as improve the efficiency of nutrient uptake and utilisation by plants.
