By: Kandil AA, AE Sharief, Ola S.A. Shereif Key Words: Canola, Cultivars, Salinity stress, seedlings characters. Int. J. Agr. Agri. Res. 8(2), 10-18, February 2016. Abstract To study the effect of salinity concentrations on seedlings parameters of some canola cultivars, a laboratory experiment was conducted at Agronomy Department Laboratory of Seed Testing, Faculty of Agriculture, Mansoura University, Egypt, during December 2013. The experiment included two factor, the first factor included three cultivars of canola i.e. Serw 4, Serw 6 and Serw 51 and the second factor included ten concentrations of salinity as NaCl i.e. 0.0 (control treatment), 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, and 1.8 % NaCl). The results showed that Serw 6 cultivar significantly exceeded the other studied cultivars in root and shoot lengths and shoot fresh and dry weights. Whilst, Serw 51 cultivar significantly exceeded the other studied cultivars in root fresh and dry weights, seedling height reduction (SHR), relative dry weight and chlorophyll content in leaves. Salinity stress significantly affected seedlings characters of canola. Due to increasing salinity levels from 0 (control) to 1.8% NaCl, seedlings characters of canola was significantly decreased. It could be concluded that for maximizing canola seedlings parameters, germinated seeds of Serw 6 or Serw 51 cultivars under control treatment (without salinity stress) or under conditions of 0.2% NaCl.

The contamination and potential ecological risk posed by heavy metals from thirteen (13) sediment samples from different sampling sites along the lower portion of Agusan River were analyzed and assessed using different pollution indices. The results obtained shows that the total digest concentrations of different heavy metals under investigation have the following order: Cd < Pb < Zn < Mn, for both first sampling periods. The speciation and distribution pattern have shown that significant amounts of all metals are present in the residual fraction. Similarly, oxide-bound and organic-bound fractions were found to be highly important for Zn and Mn while Cd and Pb were significantly associated in the residual and exchangeable fractions. The results of different pollution indices moreover, showed that among all the heavy metals being studied, Cd posed the highest environmental risk across all sampling stations in both sampling periods and Mn metal was highly enriched and abundant in all of the sampling stations. Importantly, PCA results suggest that Zn, Mn and Pb may have the same origin while Cd might be coming from different sources, and this is corroborated well with the cluster analysis results. The results obtained from this work provide baseline data on the assessment of heavy metal pollution in the lower portion of Agusan River. Importantly, the acquired environmental indices will certainly help safety managers in assessing and interpreting the potential risk of the sediment associated chemical status that might adversely affect aquatic organisms in the selected sampling sites.
