DALMASSO, Antonio  e  DUPLANCIC, Andrea. Malephora crocea var. purpureo-crocea (Haw.) Jacobsen & Schwantes (Aizoaceae), alien species of interest for xeriscape. Multequina [online]. 2018, vol.27, n.1, pp.35-39. ISSN 1852-7329.

Malephora crocea var. purpureo-crocea (Aizoaceae) presents great adaptation to the conditions of arid and semi-arid zones of Argentina. The objective is to evaluate the response of growth parameters of the species under different watering levels. Six treatments were applied between 100 mm to 500 mm/year of irrigation and variable frequency. Each treatment consisted of 10 replications and the study lasted two vegetative cycles. Then the plants were removed and the following variables were determined: dry weight of standing and underground biomass, number of stems and internodes, length of stems and primary root, and number of flowers. All the variables were statistically higher in the treatments with higher water input. None of the treatments had loss of specimens. With an irrigation supplement of 100 mm/year it would be an interesting species in xeriscape for the arid region of Argentina.
