Effect of silver nitrate on sex expression and pollen viability in parthenocarpic cucumber (Cucumis sativus L.).
1988
Kasrawi M.A.
A study was carried out to investigate the effect of silver nitrate (AgNO3) concentration, number of sprays and time of application on sex expression and the pollen viability of parthenocarpic cucumbers. Induction of staminate flowers is dependent upon AgNO3 concentration, growth stage at time of application, and number of sprays. The greatest number of staminate flowers were produced on plants sprayed twice with 300 ppm AgNO3 at one week intervals, with initial spray at the first-true-leaf stage. Second and third sprays of 200-500 ppm AgNO3 applied at the first-true-leaf stage produced maximum number of staminate nodes. Plants sprayed at the first-true-leaf stage produced staminate flowers starting at the first node and at time of onset of flowering. AgNO3 treatment had no effect on viability of pollen grains.
