How to make plant crossbreedings: It is harder to give a general explanation about how to
or hybridise, two different
plants, because the details do vary from
one organism to another.
First it is necessary to take the pollen from the
anther (maleorgans) of one plant and move it to the
stigma, (femaleorgan) of
another, making sure that no other pollen apart from the one that is
supplied can reach the stigma.
In autosterilespecies, it is quite easy, the
pollen can be collect
(for example whit a small painting brush or with a pair of forceps) and then
placed directly over the receptivestigma, after that the
flower can be covered with a paper bag.
are also quite easy, because the male and female
flowers are separate.
But autofertile species are much more difficult. In these plants, a
single flower has both male and female parts. For this reason it is
necessary to remove the male parts (emasculation) from the “mother”
flower before adding the pollen from the “father”. The pollen may be
transferred with a fine paintbrush.
