Morphological and anatomical responses of four wheat cultivars to water stress

Abstract EN

Apot experiment was conducted in greenhouse station, Biology department, Science college, Salahhadin University to study the effect of three drought periods (0, 7, 14, and 21 days) on four soft wheat cultivars (Amede, Aksad, Florkwa and Aras) under three water stress conditions.

Factorial Completely Randomized Designs were used with four replication for each treatment and the means were compared using least significant difference test.

Morphological and yield characteristics, treatments significantly decreased plant height, tiller numbers, flag leaf length and width, spikes length, spikes number, weight of 100 grains and dry weights of the plants for all cultivars.

While for anatomical characteristics treatments significantly increased cuticle thickness, xylem diameter and upper epidermis for all cultivars and lower epidermis only for Asked cultivar and decreased phloem diameter and stomata numbers as compare to control
