Style of Stigma Interaction

The style has been distinguished into two types:

In open styles a stylar canal is present which is lined with a well-developed glandular epidermis (monocotyledons),
In closed styles a compact core of transmitting tissue is present (dicotyledons, especially in Gamopetalae).

A correlation between the types of style with that of composition of the stigmatic exudate has been observed. The solid style exudate is usually rich in polysaccharides, lipids and proteins whereas, open style exudates only have polysaccharides.
