title: Formation of root hairs by the wheat Triticum Vulgare Host. Trichoblasts.
abstract: The process of root hair formation has been studied by light-, transmission-and scanning electron microscopy. In the course of root hair development a break of the outer cell wall is observed by electron microscopy. It apparently occurs after the break of the fibrillar layer. The break of the outer layer of the cell wall is assumed to represent the break of the outer mucilage, the cuticle and the adjoining amorphous matrix with irregularly oriented cellulose microfibrils. The scheme of successive ultrastructural changes in the outer cell wall pattern during root hair formation is presented.
