• Photosynthetic pigment

A pot experiment was conducted to elucidate influence of foliar application of various combinations of BR and macro- nutrients (NPK) nutrition on morphological and physiological attributes of Leymus chinensis (Trin.). The results revealed that BR and NPK nutrient mixtures altered growth, photosynthetic pigments, and osmolytes of L. chinensis (Trin.). Furthermore, analysis of various factors revealed that most effective application was the treatment of urea 1%, potassium dihydrogen phosphate 1% and BR 0.1 mg/l which proved most advantageous pertaining to plant height, fresh and dry weight, biosynthesis of chlorophyll, carotenoids, soluble sugars and proteins. Results suggested that foliar applied BR and NPK mixtures on L. chinensis improves growth and alters plant physiology.
