1. Intraspecific and reciprocal pollinations were made with Rhododendron japonicum and R. mucronatum, and pistils were collected at established intervals after pollination. This material was sectioned and examined to observe rate of pollen-tube growth, fertilization, and subsequent seed development. 2. The azalea megagametophyte is typical of the Ericales. 3. Pollen-tube development is slow, and callose plugs occur frequently throughout the length of the tubes. Fertilization occurs about 96… CONTINUE READING
