Nitsch Medium
The medium defined by Nitsch was used in the production
of haploid plants of various species of Nicotiana raised from pollen grains. In
this procedure, pollen that were still uninucleate were isolated and then
cultured in vitro. Some pollen grains proliferate into embryo-like structures
that develop in stages similar to those of zygotic embryos. The plantlets
matured and flowered profusely, but did not set seed.
