Abstract

Aim: The main objective of the study was to estimate response of some wheat varsities and the effect of varieties on the given water uptake, germination and growth parameters and then determinant the salt tolerance level of varieties and compare salinity tolerance between varieties to identify.

Materials and Methods: Charmo, Maroof and Alla were new promising rust-resistant wheat varieties had been tested for their salinity tolerance through seed water uptake, (germination percentage and germination mean), as well as the growth of radical and plumule. The varsities  were tested for their salt tolerance level by using salt solutions concentration levels with a control,  0.01, ,0.03.0,05, 0.07, and 0.09 molL -1, which were answer to 0.0,  0.58, 1.75,  2.9 , 4.01 and 5.26 gL -1, that symbolized as  C0, C1, C2, C3, C4 and C5.

Results: The results showed significant effects of varsities on water uptake, germination percentage germination meantime, wet and dry radical, but not significant effect on radical number and length as well as plumule length and wet dry plumule. The effects of salt levels on germination parameters and growth of varieties, a significant effect of salt on germination mean, germination percentage, radical and plumule length as well as on wet radical weight. And the interaction between varsities and salt levels, the result has shown a significant effect of interaction between varsities and salt levels on dry radical. Salt levels from C3 have indicted to have a significant effect on germination on wet radical but not a significant effect on water uptake, dry radical, as well as on wet and dry plumule.

Conclusion: It was concluded that the effect of varieties on germination and growth parameters showed that charmo and maroof are better than Alla, Charmo and Maroof found tolerating C2 inspite of Alla.
