Effect of Seed Priming and Molybdenum Foliar Application in some Physiological and Anatomical Traits in Wheat Crop (Triticum aestivum)

Abstract

A laboratory and field experiments subsequently were conducted in order to investigate the effects of molybdenum in some physiological and anatomical traits in wheat. Four treatments of seed priming were used in lab experiment (0, 20, 40 mg Mo L-1 and hydro-priming with H2O) and laid out in CRD with four replications, whereas in the field experiment, three treatments of molybdenum were used as seed priming (0, 20, 40 mg Mo L-1) and as foliar application (20, 40 mg Mo L-1 and spraying with water) and laid out as factorial in RCBD with three replications. Results showed that the concentration 40 mg Mo L-1 was significantly superior as seed primer in length and fresh and dry weight of radical and coleoptile, coefficient of germination velocity and number of spikes in square meter, as well as in number of grain per spike and fertility ratio as foliar application. Anatomically the treatments were significantly differed in leaf anatomy. The concentration 40 mg Mo L-1 showed that the leaf was slightly wrapped and the upper and lower epidermis cell were larger and not organized while chlorenchyma cells were smaller and also not organized. It can be concluded that the use of molybdenum is very useful in wheat as seed primer or foliar application and it can be recommended to use it in higher concentration in different growth stages in wheat.
