Abstract:

The present experiment was performed throughout two successive seasons of 2014/2015 and 2015/2016 at a Private Farm in Fayoum Governorate - Egypt. It intended to find out the individual and the combined effects of phosphorus fertilizer at four levels (20 “is considered as control”, 40, 60 and 80 –unit/fed.) and gibberellic acid at four concentrations (control, 75, 150 and 300 ppm) on growth, flower quality, corms production, chemical composition and concrete oil percentage of tuberose (Polianthes tuberosa, L.) cv. Double. The results emphasized that using phosphorus fertilizer or gibberellic acid treatments had significant response on all parameters in this study. Likewise, resulted in supported vegetative growth parameters and improved flowers quality, as well as, increased concrete oil percentage and chemical constituents of essential oil, especially using the medium and high levels. Additionally, the interactive between various levels of phosphorus fertilizer and different concentrations of gibberellic acid improved all the studied parameters, particularly using the combinations between phosphorus fertilizers at 60 –unit/fed and together with gibberellic acid at 150 ppm.


Keywords: Tuberose, Phosphorus fertilizer, Gibberellic acid, Vegetative growth, Flowering production and essential oil.
