摘要: The anther connective tissue and hypodermal stomium between adjacent locules in the anthers of Capsicum annuum L. (Solanaceae) are sites formation calcium salt crystals with four different habits. spatial temporal associations these idioblastic cells which they form indicate that crystal sand occurs earliest development near single vascular strand, followed by spherulites prismatic farther out tissue, finally druses occur stomium. Both encased chambers associated distinct membranes, whereas not bounded any apparent membranes but surrounded dense material is rich stains positively for polysaccharides proteins. Quite often observed within a cell contact each other. X-ray diffraction preparations containing all habits elemental analyses crystals, as well visual observations acid treatments, suggest consist oxalate. degenerate at pollen stage causing to fuse. Shortly afterward, epidermis splits open along length releasing pollen. It suggested idioblasts involved this process, possibly temporally orchestrated sequestration from both cytoplasm wall.
