Development of D-type Stomata in the Leaves of Ilex crenata var. convexa

Description
Summary:Small black or brown scars are scattered over the lower epidermis of the mature leaf of Ilex crenata var. convexa that are interpreted as wound responses to the deterioration of large stomata. These stomata are few in number, large, arise early during development, and are short-lived compared to typical leaf stomata. Such developmental, or d-type, stomata are arranged in an ordered pattern over the leaf surface as demonstrated by nearest neighbour and quadrat analyses. Computer models of several possible modes of origin of d-stomata were tested for their similarity of quantitative features of spatial distribution to that for actual material. The one model that gave acceptable results in all tests was one in which each newly formed d-stomate produces a zone of inhibition that prevents additional d-stomata from forming during subsequent growth. The usefulness of quantitative descriptions and computer modelling of patterns in plant morphology is discussed.
