Abstract:
The study was conducted during the years 2020 and 2021 at the Scientific Agricultural Research Center in Lattakia, affiliated with the General Commission for Scientific Agricultural Research. with the aim of studying the effect of Stratification, lighting, and storage on the germination of seeds and embryos of wild apple Malus trilobata (Lab). Seeds were collected from one of the type of the wild apple species Malus trilobata (Lab). from the site of Khirbet al-Sindyaniyah in the Qardaha region in Latakia Governorate, which is 900 meters above sea level. The results of the study showed that the Stratification at (6-8) degrees C° is very effective in breaking the dormancy of the seeds of the studied species. The 90 day Stratification treatment outperformed the rest of the treatments with a 100% germination rate, while the non-stinging seeds did not germinate at all. The study also concluded that lighting is a major factor in the germination of embryos of the studied species. The average percentage of germination did not exceed 20% in the absence of lighting. While it reached 100% in the presence of full lighting, the study also showed that the seeds do not enter a secondary dormancy phase after being stored. The average percentage of seed germination after a year of storage reached 100% after cold Stratification treatment for 90 days, and the same applies to embryos grown at successive intervals of 4 months; While the complete seeds did not germinate at all.
Key words: wild apple Malus trilobata (Lab), Stratification, Lighting, seeds, embryos.
