Subject field(s)
  • Plant Biology

Two classes of pollen grains have been found in Nicotiana tabacum anther cultures : normal and atypical pollen. The normal grains stained intensely with acetocarmine, followed the gametophytic development pathway, and degenerated when cultured in vitro. The atypical grains were smaller, stained weakly, and followed the embryogenetic pathway. This second class of grains was named p-pollen(pre-mitotic pollen) by Heberle-Bors and Reinert(1979).

Reproductive processes in some plants can be influenced by air pollutants. In the bracken fern(Pteridium aquilinum) the alternation of gametophyte and sporophyte generations may be affected by acid precipitation. For fertilization to occur in gametophytic plants water must be present to provide a medium for the transference of motile sperm which are provided with flagella.
