“…Kinetin is also used to enhance the crop growth under diverse conditions of salinity (Salama andAwadalla, 1987), water-logging (Gadallah, 1995), and soil acidity (Gadallah, 1994). Foliar applied kinetin tends to combat with increased concentration of abscisic acid and hence delays the leaf senescence by decreasing the chlorophyll and protein degradation possibly due to increased leaf sugar contents (Ali et al, 2008). Silver nitrate is also very helpful to mitigate the adverse effects of stresses due to temperature extremes.…”

The performance of spring maize hybrids are severely affected by high temperature at reproductive phase causing marked reduction in yield. Exogenous application of natural and synthetic plant hormones may induce tolerance against temperature constraints. Therefore, a field study was conducted to evaluate the performance of two maize hybrids i.e. PS525 (heat tolerant) and P1543 (heat sensitive) with exogenous application of growth promoting substances (3% moringa leaf extract (MLE), 75 mg L-1 kinetin, 85 mg L-1, silver nitrate and 0.1 mg L-1 triacontanol). Plants without spray (control) and water spray were taken for comparison. Different agronomic, physiological and quality traits were measured using standard procedure. Both hybrids showed improved performance in response to foliar spray of growth promoting substances. But maximum results were observed in hybrid PS525 with foliar application of 0.1 mg L-1 triacontanol and followed by 3% MLE. Enhancement in maize growth and yield through foliar spray of growth promoting substances was attributed more likely due to improved chlorophyll and relative water contents, LAI and decreased cell membrane permeability.
