Relative Salt Tolerance of Switchgrass (Panicum Virgatum) Varieties During Germination Development

X. Fan, X. Hou, J. Wu & Y. Zhu
In November 2010, one experiment was set up to investigate switchgrass salt tolerance in the germination phase. Seeds of nine varieties in four replicates were exposed to solutions containing 0 (distilled water), 50, 100, 200, 300 and 400 mM NaCl. The results show that seed germination characteristics and seedling biometric traits resulted significantly influenced by salt levels, varieties and the interaction of both. Plant responses resulted progressively worse with increasing salt levels with the exception...
