New form of azeda reproduction identified in the Iberian Peninsula

Researchers from the Center for Functional Ecology at the University of Coimbra (UC), in partnership with the University of Vigo, have identified a new way of reproducing the invasive plant. Here, the plant, commonly known as "soursop" or "yellow clover", is able to reproduce by seed (sexual reproduction), an ability that until now had been exclusive to the area where the species is native - South Africa.

João Loureiro, coordinator of the study co-funded by FCT, explains that this way of reproducing sorrel, which spreads preferentially in agricultural areas, "allows it to cross with other species, which increases its genetic diversity and makes it possible to combine characteristics that can make plants more aggressive and damaging to the ecosystem".

The results obtained so far show that the propagation process "has become faster, easier and very aggressive", with an impact "on the reproduction of native plants in invaded areas, which could compromise the reproduction of some species and affect the dynamics of natural populations. For example, there has been a negative impact on kale".

According to the researcher, the study aims to provide relevant information to "better understand this species and thus develop measures to control and eradicate the plant".
