Assays for the cultivation of two native plant species largely utilized as aphrodisiac in the central region of South America
The two vegetable species more frequently used as aphrodisiac in the central region of South America are: A-Catuaba [Anemopaegma arvense (Vell.) Stellfeld & J. F. Souza, (Bignoniaceae)] and B-Nó-de-Cachorro [Heteropterys aphrodisiaca Machado, (Malpighiaceae)]. These are native plants withdrawn from the natural environment which is getting degraded. In order to prevent extinction of species A and B, a viable alternative is to cultivate them. To contribute for the definition of a rational production system of these two species, an effective single (AA or BB) or consorted (AB or BA) cultivation system was investigated in Cáceres, MT, Brasil, from Dec 2004 to Aug 2006), through a series of experiments, executed in two phases: „I“–„nursery“ (during 142 days, plants spacing of 12cm); „II“„definitive cultivation“ (during 218 days, plants spacing of 50cm). In the nursery, the growth (cm) of the A species was greater in the consorted (12.93) than in the single (9.92) system while the B species grew less in the consorted (11.33) than in the single system. In the definitive cultivation, the height of the B species (23.85) was not affected by the system while the A species grew less in the consorted (8.61) than in the single (11.70) system. The A species behaved in opposite ways in the single and consorted systems when grown in nursery or definitive cultivation while the B species was affected by the cultivation system only when grown in the nursery. Different responses of plants are strategies developed to adapt to adverse conditions in distinct development stages. This is expressed through alelopathic effects, adaptative capacities, morphological and physiological characteristics as well as phytochemical constitution, important for the explotation of these species.
