The effect of thidiazuron on the yield of salinity stressed wheat
1992
Beckett, R.P. | Van Staden, J.
The effect of the phenylurea-like compound thidiazuron with reported cytokinin-like activities on the yield of salinity-stressed wheat was investigated. Application of thidiazuron during early growth reduced the yield of unstressed plants had little effect on moderately stressed plants, and at high concentrations significantly increased the yield of highly stressed plants. A decrease in grain N concentration accompanied the yield-increase. Although thidiazuron reduced spikelet and grain number in highly stressed plants. In plants treated with high concentrations of thidiazuron an increase in grain weight mare than compensated for the lower grain number. A possible mechanism for the thidiazuron-induced increase in yield is discussed.
