The day of the puncture is what is known as day 0 of the embryonic development, as this is when fertilization (union of the egg and sperm) occurs. Ammonium nitrate is better than KNO3, NaNO3 and (NH4)2 HPO4. Culture in the in vitro fertilization laboratory begins after obtaining the eggs by means of follicular puncture, also called ovum pick-up. In his experiment, he had isolated embryos of two plants belonging to crucifers (Cochlearia and Raphanus). Laibach( 1952) use of embryo culture technique in inter specific crosses of Linum. Definition of embryo culture techniques in the Definitions.net dictionary.
