Cite article:- Nejat Najmeh, Sadeghi* Hossein (2023). RESPONSE OF ZIZIPHUS SPINA-CHRISTI (L.) WILLD SEEDLINGS TO NACL-INDUCED SALINITY. Agricultural Science Digest. 32(1): 61 - 65. doi: .
Ziziphus spina-christi is a fruit tree species growing wild in arid and semi-arid areas of Asia and Africa where rural populations intensively use its fruits, leaves, bark and wood. However, little is known about the effects of salinity, a widespread problem in these regions, on early growth and chemical composition of this species. Six weeks old seedlings of Z. spina-christi germinated in a full strength Hoagland solution were subjected to 3.2, 6.4, 9.6 and 12.3 dSm-1 NaCl compared to the unstressed control plants. The results showed that salinity levels of 9.6 and 12.3 dSm-1 reduced plant height, leaf number, total leaf length and breadth and dry matter by > 50%. Salinity levels of 3.2, 6.4, 9.6 and 12.3dSm-1 NaCl enhanced leaf water contents by 53, 71,94 and 124 fold higher Na and 16, 25, 27 and 29 fold higher Cl respectively, compared to control plants.
