Freezing tolerance in alpine plants as assessed by the FDA-staining method
We established a method employing fluorescein diacetate (FDA)-staining with a laser scan microscope for evaluation of the freezing tolerance of leaf mesophyll cells, and applied it to assessments of freezing tolerance in leaves of nine alpine plants, Arcterica nana, Cassiope lycopodioides, Diapensia...

We established a method employing fluorescein diacetate (FDA)-staining with a laser scan microscope for evaluation of the freezing tolerance of leaf mesophyll cells, and applied it to assessments of freezing tolerance in leaves of nine alpine plants, Arcterica nana, Cassiope lycopodioides, Diapensia lapponica, Empetrum nigrum, Loiseleuria procumbens, Phyllodoce nipponica, Rhododendron aureum, Schizocodon soldanelloides, and Vaccinium vitis-idaea, which naturally occur on Mt.
