Abstract
Na CI salinity at 2500 and 500 ppm decreased wheat plant growth expressed by plant height, number of fertile tillers, dry weight of shoot system (g) and flag leaf area (Cm) as well as photosynthetic pigment concentrations in flag leaf in both seasons. Accumulation of both Na‘ and Ci‘ ions in the shoot system was increased With increasing NaCl levels, while K’ concentration was decreased. Yield and its components represented by number of spikes per plant, spike length (cm); number of spikelets per spike, grains weight per spike and 1000-grain weight as well as carbohydrate, protein, N. P and K percentages in the grains were decreased compared with control. Anatomically, salinity decreased root diameter, cortex thickness, vascular cylinder diameter and metaxylem vessel diameter as well as flag leaf thickness in the keel region, mesophyll tissue thickness, main vascular bundle dimension, xylem and phloem tissues thickness and metaxylem vessel diameter. Treatment with either trehalose or glycinebetaine at 100 ppm and their interactions with salinity increased all the above mentioned parameters in both non-salinized and salinized plants. Trehalose was the most effective in this respect. Treatments with either trehalose or glycinebetaine are recommended not only for improving plant growth and yield of wheat plant but also for recovery the adverse effects oi salinity. '
