The AS-CO (A. asterias x A. coahuilense
F1 hybrid ) shows intermediate density of
hairy scales, while the number of
ribs vary from 5 to 8.
Cultivation: Relatively easy to grow. It is sometime seen as a grafted plant but grows very
well on its own roots too. Use mineral well
permeable substratum with little organic matter (peat, humus). Water
sparingly from
March till October and keep perfectly dry in
winter
at temperatures from 5 to 15 degrees centigrade.
(but it is
Hardy to -7°C for short periods) In
the rest period no high atmospheric humidity!!
Sun Exposure:
Light shade to full sun.
Propagation: They can be propagated easily from seed or graft.
How to make plant
crossbreedings:
To
crossbreed,
or
hybridise, two different
plants it is necessary to take the
pollen from the
anther (male
organs) of one plant and move it to the
stigma, (female
organ) of
another, making sure that no other
pollen apart from the one that is
supplied can reach the
stigma. In
autosterile
species
(like the plant in example) 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
receptive
stigma, after that the
fecundated
flower can be covered with a paper bag.
