Abstract:
This study was conducted during the year 2022 with the aim of studying the effect of location, depending on the altitude above sea level, on the germination rate of seeds of some environmental types of carob at the Agricultural Scientific Research Center in Lattakia, Where carob seeds were collected from locations varying in altitude above sea level (Umm al-Tuyur – Sanobar Jablah – Jibol – Bastoir). then they were germinated and the growth and development of the seedlings were monitored. It included four treatments: A1 (Umm al-Tuyur), A2 (Sanobar Jablah), A3 (Jibol), and A4 (Bastoir). Each treatment included three replicates, with an average of fifty seeds per replicate. The experiment was designed using a completely randomized block method. The results were statistically analyzed using the program (12GENSTAT) and the differences were tested using the least significant difference (L.S.D) method at a significance level of P=0.05.The results showed a clear effect of height above sea level on the germination rate and germination time, as Umm al-Tuyour seeds exceeded the rest of the sites with a germination rate of 90.67%. Umm al-Tuyour seeds also began to germinate four days earlier than Bastoir seeds, and the speed and uniformity of germination also improved. The weight of 1000 seeds was higher in the Umm al-Tayur site, significantly superior to the rest of the sites. The seeds of Umm al-Tuyur and Sanobar Jablah were also significantly superior to the rest of the sites in terms of the values of shoot and root systems, diameter, and number of leaves.
