In Vitro Double Fertilization
In vitro double fertilization is often used to study the molecular interactions as well as other aspects of gamete fusion in flowering plants. One of the major obstacles in developing an in vitro double fertilization between male and female gametes is the confinement of the sperm in the pollen tube and the egg in the embryo sac. A controlled fusion of the egg and sperm has already been achieved with poppy plants. Pollen germination, pollen tube entry, and double fertilization processes have all been observed to proceed normally. In fact, this technique has already been used to obtain seeds in various flowering plants and was named “test-tube fertilization”.

Famous quotes containing the word double:
“... the next war will be a war in which people not armies will suffer, and our boasted, hard-earned civilization will do us no good. Cannot the women rise to this great opportunity and work now, and not have the double horror, if another war comes, of losing their loved ones, and knowing that they lifted no finger when they might have worked hard?”
—Eleanor Roosevelt (1884–1962)
