Vegetative propagation of caltrop (Tribulus cistoides L.), multipurpose ornamental plant

Abstract:

The caltrop (Tribulus cistoides L.) is a multipurpose specie well adapted to semi-arid and arid conditions of Venezuela, and is used in other countries for ornamental purposes. The aim of this study was to evaluate the effect of cutting type (apical and subapical), concentration of indole butyric acid (IBA) (0, 500, 1000, 2000 and 4000 mg.kg-1) and relative humidity around the cutting (RHC) (environment shading-without humidity chamber-and close to 100% with humidity chamber) on the rooting of caltrop. After five weeks it was found that only the RHC influenced significantly (P<0.01) in the percentages of viable cuttings, rooted cuttings, number of roots per cutting and root length. It was concluded that planting apical or subapical cuttings, without IBA application, and directly exposed to the environment under shade allowed high percentages of living and rooted cuttings, and greater root development.
