The present study was conducted during the 2022 season on seeds of Balady Ziziphus (Zizphus spina-christi (L.) Desf. in El-Kwamel at Sohag University, Sohag, Egypt. This study examined how (Z. spina-christi) responded physiologically, in terms of seed germination, to scarification by using sandpaper and cracking of the seedcoat, and sulfuric acid (98%), was applied for (60 and 120 min) then, the seeds were washed and placed underwater for 30 minutes. As a result, the maximum value of germination percentage, shoot length, root length, number of root hairs, and number of leaves was recorded by soaking in sulfuric acid (98%) compared with the control. Therefore, it is concluded that using soaking (Z. spina-christi) seeds in sulfuric acid (98%) for (120 min) once led to clear enhancements in the majority of the tested parameters of (Z. spina-christi). This study explored treatments (Scarification by using sandpaper and cracking of the seedcoat, sulfuric acid (98%) for 60 minutes, and sulfuric acid (98%) for 120 minutes). After 60 days have been determined of germination percentage (G.P) and Mean germination time (MGT), root and shoot lengths were measured with the help of a ruler and expressed in centimeters (cm). After that calculated, the number of root hairs and leaves was. The emergence percentage was highest after immersing seeds in acid for 120 minutes, while untreated seeds (control) had the lowest germination percentage. All treatments except untreated seeds significantly increased the total number of seedlings.
