Propagation of our plants is something that most of us are concerned with, and we know that this can be achieved through cuttings, self-fertile seeds, or fertile seeds. But in plants which are able to reproduce clonally (i.e. without a second plant being involved), what proportion of the progeny are produced this way? The authors examined a wild population of Mammillaria magnimamma which is under threat, and carried out experiments on controlled pollination. They found that more seeds per fruit were produced in cross-pollination, but that the population likely depends on clonally reproducing to survive.
An interesting work.
