  Salinity is one of the rising problems causing tremendous crop productivity losses in different parts of the globe. Silicon can be regarded as multi-talented quasi-essential element due to its versatile role in providing several benefits for plant growth particularly under stress conditions. The present investigation deals with the impact of potassium silicate on the germination and biochemical parameters of tomato under salt stress. Maximum seed germination of tomato seeds 98% was observed with potassium silicate. The seed germination and other growth characteristics followed the order: PS > C > NaCl (1mM)+PS > NaCl (1.5 mM)+PS > NaCl (2mM)+PS > NaCl. Application of potassium silicate significantly increased biochemical components such as pigment content, sugar, proline, protein and total antioxidant contents in tomato seedlings. Maximum total antioxidant content 55% was observed in NaCl (2mM)+PS treatment. The results revealed that potassium silicate acts as a plant growth promoter and it can be used as fertilizer for tomato under salt stress. تفاصيل المقالة

   Elouaer Mohamed Aymen 1 *, Ben Fredj Meriem 1, Zhani Kaouther 1,Hannachi Cherif 1  Sousse University, High Institute of Agronomy, Chott Mariem, 4042, Tunisia     * Corresponding author E-mail: aymenouaer@gmail.com   Received: 17 July 2013 Accepted: 12 November 2013   Abstract   This experiment was conducted to evaluate the effects of NaCl priming on growth traits and some biochemical attributes of safflower (Carthamus tinctorius L. cv Safola) in salinity conditions. Seeds of safflower were primed with NaCl (5 g L-1) for 12 h in 23 °C. Primed (P) and non primed (NP) seeds were directly sown in the field. Experiments were conducted using various water concentrations induced by NaCl (0, 3, 6, 9 and 12 g L-1) in salinity experiment. Results showed that growth (plant height, fresh and dry weight) and biochemical (chlorophyll, proline and proteins content) of plants derived from primed seeds were greater of about 15 to 30% than that of plants derived from non primed seeds. It seems that salinity tolerance in priming resulted plants was due to higher potential of these plants to accumulate more biochemical attributes (more chlorophylles, proline and proteins in primed plants than controls ones).         تفاصيل المقالة
