Abstract:

Cycocel ameliorated the osmotic stress at -4bar PEG by increasing chlorophyll contents in slow expanding shoots and increased radicle thickness enhancing root system under water stress. Remarkable effects of CCC on radicle thickness were displayed on root cap enlargement under -4 and -8 bars osmotic stress. Root growth/ radicle length was reduced drastically in kinetin treatments under all levels of water stress. Fast growing roots act as strong sink for food reserves and grow at the expense of shoot growth. The ability of cytokinins to establish local metabolic sinks in pre-soaked seed treatments could change the direction of assimilate transport and synthesis of auxin, gibberellin and ethylene in shoot and root meristems inverting the source-sink relationship in favour of shoot growth. Greater nitrogen productivity of seedlings emerging from protein rich pearl millet seeds presoaked in cytokinin may prove beneficial in increasing fodder yield under drought conditions. Cycocel treatment may have direct consequence on nutrient or water uptake and aboveground biomass/productivity under various levels of stresses.
