Abstract:

The cells full of crystals observed in orient tobacco were verified to be crystal idioblasts.The crystals observed by SEM was multiangle. The ultrastructure of crystal idioblasts changed during the maturing of leaves,the plastids were gradully disppeared while cytoplasmic was gradully dry . The content of calcium was higher in the crystal idioblasts than that of common cells,and so the crystals might belong to calcium salt crystals.Whether the crystals included other organic components were not known.The separation method of crystal idioblasts was studied.
