Abstract
The current study was carried out at a private farm in Al Sananiyah, Damietta Governorate, Egypt during two successive seasons of 2018/19 and 2019/20 on two years-old seedlings of Arabian jasmine plants to investigate the effect of foliar spraying with boron (80 ppm), zinc (120ppm), salicylic acid (200ppm) and their combinations on vegetative growth, flowering, and biochemical characteristics of
Arabian jasmine plants. The most important results indicated that foliar spraying with salicylic acid alone or in combination with Zn led to a significant increasing of the most vegetative growth characteristics and biochemical characteristics (tryptophan, polyphenols, total carbohydrates and reducing sugars), while spraying with Zn alone increasing the dry weight of shoots and NPK% during the two seasons. In addition, foliar spraying with zinc or salicylic acid alone or in combination led to a significant improvement in the flowering characteristics (number of total flowers, number of flowering points, number of clusters, number of single flowers, mean number of flowers/cluster). Moreover, foliar spraying with boron alone gave the highest values for flowering characteristics except for the mean number of flowers/clusters. However, gradual decrease in the leaf pigments content (chlorophyll a, b, total chlorophyll and carotenoids) were recorded in all spraying treatment comparing to the control. Accordingly, this study recommends foliar spraying with the combination treatment containing zinc at120 ppm and salicylic acid at 200 ppm to improve the vegetative growth and to increase the flowers number of Grand Duke of Tuscany Jasminum sambac L. plants.
