ABSTRACT
The effect of salinity (0, 4, 8 or 12 dSm-1) induced by NaCl in irrigated water was studied
on the shoots of wheat cultivars. After 80 days from sowing, fresh and dry weight of shoot
and shoot content of Ntot, P, K, Ca, Mg and Cu were significantly decreased as salinity
level increased, whereas Na, Cl, Mn and Zn were increased in the shoot...
This experiment was conducted in pots with a randomized complete design to study the
effects of foliar application with Hoagland’s solution (0, 1/4, 1/2, 3/4 and full strength) on
some morphological, physiological and yield characters of barley cv. Towetha. Both 1/4 and
1/2 strength treatments showed significant increase in all morphological (heigh...
ABSTRACT
A greenhouse pot experiment was carried out during October 26, 2009 to May 15, 2010. Winter wheat
grains (Triticum aestivum L.) cv.Rizgary was used to investigate the role of spraying the plant with
200ppm ascorbic acid (AsA) on vegetative, biomass and some chemical and biochemical constituents of
leaves under drought condition. The water...
Effect of spray application with salicylic acid (200ppm) on shoot and root biomass, some ionic and biochemical constituents on shoots of wheat (Triticum aestivum L. var. Cham 6) plants exposed to salinity stress induced by (2%, 3% and 4%) NaCl solutions in the irrigated water were studied. Salicylic acid led to significant increases in shoot and ro...
