The limited number of spikelets and the rate of abortion of the florets causes huge losses in the grains yield of bread wheat, so regulating the differentiation of spikelets and florets may be contributing to solving that problem!
Zeatin promotes floret development and significantly increases the number of fertile florets as well as grain set, especially at the stage of anther-lobe formation. Zeatin also increases the sugar concentrations in spikes at anthesis. So regulating the differentiation of spikelets and florets through exogenous application of hormones is possible.
