Time relationships of sporopollenin synthesis associated with tapetum and microspores in Lilium.
The development of the sporopollenin orbicules (Ubisch bodies) on the tapetal cells of Lilium begins while the spores are still enclosed in the meiotic tetrads. Spherosome-like structures, the pro-orbicular bodies, accumulate in the vicinity of the plasmalemma early in the tetrad period, and are ext...
