| Abstract | ||
| This study was conducted in the laboratories of the Faculty of Science and glass house of the Agriculture Department of the province of Diyala in the growing season (2011-2012) in order to study the effect of the interation between salinity and plant hormones and its impact on the growth and evolution of the wheat plant Triticum aestivum L. , And which carried out two stages first agriculture in dishes using concentrations of salt increased (0,25,50,75,100,125,150) mMol / L to study the germination percentage and speed, and the length of plumule and radicle, the second using soils levels saline (10.7 , 7.5, 4.7)ds .m-1 to study the effect of salinity and interfere between salinity and plant hormones in plant growth wheat and evolution using some landmarks phenotypic and physiological shoot length, and the content of plant protein and Carbohydrate, as results showed that salinity increasing led to low germination, speed and length plumule radicle and the length of the shoot, also declined content of plant protein and carbohydrates. Availability of plant hormones led to reduced negative effects of salinity as improved properties plant morphological and physiological, and results showed that plant hormones play a big role in improving traits and especially sodium content, which witnessed a decline in its content, as results showed that the gibberellin an important role in increasing the proportion of germination and speed where gave higher values, either hormone kinetin had a role more in increase plumule length and radicle, and the length of the shoot, while the rest of the qualities he was interfere between (K + GA3) significant effect in giving the highest values in the content of plant proteins and carbohydrates | ||
