The stylar transmitting tissue

The differentiation of the transmitting tissue of the style of Petunia hybrida was investigated with the electron microscope. The cells of this tissue are surrounded by an intercellular substance. The same holds true for a number of styles of other investigated species. This intercellular substance may not be compared with a middle lamella. The earlier suggestion, that the transmitting tissue of solid styles is collenchymatic in nature, is rejected.
