Effect of some medias and treatments on germination and growth of Amygdalus spartioides Spach.

Abstract

The research was carried out in the nursery of the Faculty of Agriculture in Damascus during the years 2018 and 2019 in order to study the effect of the soil media components (soil; agricultural soil + fermented municipal fertilizer 1: 2; sand + fermented municipal fertilizer 1: 2; agricultural soil + sand + fermented municipal fertilizer 1: 1: 1), and the period of stratification (control, 4 weeks, 6 weeks), and gibberellin concentration (control, 750 ppm, 1500 ppm) in the germination and plant growth of Amygdalus spartioides.

The results for the average germination percentage showed that the treatment of seeds with gibberellin at a concentration of  750 ppm with 4 weeks stratification in each of the two medias showed that soil + sand + fertilizer (73.33%) and soil + fertilizer (68.33%) were significantly superior to the rest of the treatments.

As for the average plant height, the plants outperformed in the media: soil + sand + fertilizer from the stratification treatment 4 weeks and gibberlin at a concentration of  750 ppm (65.67 cm) significantly over the rest of the treatments.
