Abstract
The aim of this research was to study the influence of foliar spray with different concentrations of benzyl adenine on growth and flowering of stock (Matthiola incana, v. Canneto White). The experiment was carried out at nursery and laboratories of Faculty of Agriculture, Tishreen University during season 2017/2018, and included five treatments of foliar spray of BA: 0, 50, 100, 150, 200 ppm, with three replicates (30 plants for each replicate). The results showed a positive effect of BA, especially with the highest concentration, on the development vegetative parameters (plant height, leaves number, leaves area and chlorophyll content). In other hand, the best flowering parameters (flowering initiation, spike length, number of flowers on spike, and flower diameter) were obtained with 100 ppm concentration (80.1 day, 30.1 cm, 32.5 flowers\spike, 3.5 cm respectively). Growth regulator treatment had significantly economic income compared to the control, especially with 100 ppm concentration of BA.
Key words: Stock (Matthiola incana), Benzyl adenine, Growth and flowering traits.
