Interactive effect of boron and NaCl on germinatinion performance in soybean.

ABSTRACT

The present work was carried out to study the individual and combined effects of boron and salinity on soybean seed germination. The results revealed that all the treatments of both NaCl and boron (5 ppm) delayed the germination. However higher concentrations (50 and 100 ppm) of boron was found to be enhanced germination percentage over control by 10 %. The combinations of boron with NaCl (especially 5 and 100 ppm Boron with 200 mM NaCl and 50 ppm boron with 100 mM NaCl) effectively mitigate the adverse effects of NaCl on germination of soybean seeds. In addition to it 50 mM NaCl concentration was found to be reduced the delayed effects of 5 ppm boron on germination.
