Development duration in the cactus is directly related to changes in the environment caused by the management, which can result in advancing or delaying the harvest. The aim of this study was to analyse the growth, phenology and cutting time of irrigated cactus intercropped with millet, with and without the use of mulch. The experimental design was of randomised blocks (regular arrangement) with four treatments: monocropped cactus, and intercropped cactus and millet, both with and without mulch. The cladode area index and dry matter were used to calculate the morphophysiological indices. The total number of cladodes on the plant was used to delimit the phenological phases. The ideal cutting time for the crop was determined from the dry matter. Under the monocrop system with mulch, the cactus was superior to the other systems regarding morphophysiological indices. The intercrop caused a reduction in phenophase 2 of the cactus and the advancement of phenophase 3, but there was no reduction in crop yield. The ideal cutting time was between 2,300 and 2,400 ºC day. The irrigated intercropping of cactus and millet advances the cutting time of the forage cactus, irrespective of the use of mulching. |

Inselbergs support highly specialized vegetation with many endemic species. Here we studied by an integrated approach a rare and threatened species from Brazilian inselbergs. Pitcairnia encholirioides (Bromeliaceae) is included in the Red Book of Brazilian Flora, in the ‘Endangered’ category. Only one single population on unprotected private property was known at the beginning of our study. We studied several life-history traits including clonal growth, reproductive biology, seed germination and cryopreservation, and genetic diversity. Pitcairnia encholirioides has the phalanx type of clonal growth strategy. Its self-incompatible flowers are successfully pollinated by hummingbirds. However, less than 5% of clonal fragments produced flowers. Seeds can be wind-dispersed, but most of them are dispersed by gravity and fall close to the mother plant. The percentage and speed of germination were significantly affected by different temperatures, water potential, and red:far-red light ratios, although more than 80% of seeds germinated under optimal physiological conditions. The genetic diversity was very low (Hsp = 0.09) and the population was highly structured (ΦST = 0.51). The combination of dispersal mode and environmental conditions seems to be the main factor leading to the rarity of P. encholiroides. Low genetic diversity combined with small population size and low reproductive capacity suggest that the species is highly susceptible to environmental disturbance. Similarly to P. encholiroides, many species from Brazilian inselbergs are restricted to only a few localities. For more widely distributed species, a higher genetic diversity among populations has been consistently detected. The pattern of low gene flow of many species with small distributions highlight the importance of population-based conservation strategies for such taxa the areas of occurrence of which being naturally fragmented at inselberg sites. We discuss some strategies that may help in conservation of such species. MenosInselbergs support highly specialized vegetation with many endemic species.
