Fernanda da Conceição Moreira, Maria Neudes Sousa Oliveira, Mario Kiichiro Tanaka


Marketing the inflorescences of Comanthera elegans (Bong.) L.R. Parra & Giul. represents a source of income to many families from extractives communities in the portion of the Espinhaço Range located in the state of Minas Gerais, Brazil. Cultivating this species stands out by allying income generation with conservation since the species is currently endangered. This study aimed to assess aspects of the development of C. elegans in three cultivation systems: beds, rows, and whole area. Sowing took place in January 2009 and the inflorescences were harvested in May 2010, which characterized the experimental period. Emergence; plant density; rates of flowering, mortality, resprouting, and recruiting of new individuals; and production of inflorescences per plant and per area were assessed. Emergence began approximately 50 days after sowing. Plant density ranged from 130 to 350 plants.m-2 among the three cultivation systems. The highest mortality rate (18%) was observed at the peak of the dry season (August) and the overall mortality rate over one reproductive cycle was 49%. Of the plants that lost the aerial part, 36% resprouted. Sprouting and seed germination accounted for 30 and 3% of the recruiting of new individuals, respectively. C. elegans had two bloom (AprilMay 2009 and April-May 2010): 5.4% of the plants bloomed in the first season and 78%, in the second. Each plant produced between three and 178 inflorescences and the highest inflorescence production in terms of weight (232 g.m-2) and number (2,910 inflorescences.m-2) was observed in the cultivation in beds at 1,624 kg.ha-1.
