“…In the region of Lebon Régis, no difference was found among the treatments, while in Fraiburgo, the marketable production of biomass recorded in the second harvest was higher in the 40-60 % treatment when compared with the treatment with lower levels of cover. The increase in productivity of yerba mate in more shaded environments is often reported (POLETTO et al, 2010). Westphalen (2016), found that yerba mate plants that developed in environments with 40 % less solar radiation, showed higher production of marketable biomass, compared with full sunlight exposure.…”

Effect of cover on the development and production of secondary compounds of Maytenus ilicifolia and Ilex paraguariensis in agroforestry systemsEfeito da cobertura do dossel no desenvolvimento e produção de compostos secundários de Maytenus ilicifolia e Ilex paraguariensis em sistemas agroflorestais AbstractThe Midwest regions of Santa Catarina state, in Brazil, include a great diversity of forest essences with medicinal application; however, many of these resources are poorly exploited or managed in an extractive manner. This research aimed to assess the effects of canopy cover in agroforestry systems on development and production of secondary composites of espinheira-santa (Maytenus ilicifolia) and yerba mate (Ilex paraguariensis). Two experimental areas were planted following the same spacing and arrangement for the plants. Experimental blocks were set up by pruning the pioneer plants, with three variable levels of canopy cover (0-20 %, 20-40 % and 40-60 %). Plants of espinheira-santa and yerba mate were monitored for development and their marketable vegetative parts were harvested, processed and aqueous extracts were prepared for the analysis of presence of secondary compounds. The yerba mate showed the highest production of marketable biomass under high cover. By contrast, the biosynthesis of the secondary compound, theobromine, was greater in the lowest cover, while chlorogenic acid and caffeine were higher in the cover (40-60 %). Espinheira-santa showed no difference in either development or yield among the assessment treatments and, the production of phenols was lower in the cover above 40 %.

The yerba-mate (Ilex paraguariensis) has great socioeconomic importance on family farming in Southerm Brazil. One of the main yerba-mate disease is root rotting, caused by Fusarium spp. Little is known about the pathogen physiology, especially regarding the aggressiveness associated with the production of extracellular enzymes. On this work, the aggressiveness of isolates of F. oxysporum and F. solani pathogenic to yerba-mate was evaluated and it was determined the activities of extracellular enzymes catalase, laccase, cellulase, caseinase, amylase, protease, lipase and pectinases produced by Fusarium spp. in culture medium. Six isolates of F. solani and one isolate of F. oxysporum pathogenic to yerba-mate were used. The F. oxysporum isolate proved to be less aggressive in relation to the other F. solani isolates. All isolates of Fusarium spp. produced, on a semiquantitative manner, the extracellular enzymes catalase, laccase, cellulase, caseinase, amylase, protease, lipase and pectinases (polygalacturonase and pectate lyase). However, the quantity produced for each enzyme was significantly different among the isolates. With the exception of the laccase and polygalacturonase enzymes, the M7C1 isolate showed the highest enzymatic index and was also responsible for the highest percentage of yerba-mate seedlings death.

“…The fact is that Poletto et al (2010) observed that the best growth and development of yerba mate occurred at higher levels of shading. However, the cultivation of yerba mate in intercropping systems is subject to the limitation of the solar radiation due to the interception of this climatic element by the plants of the superior extract (in this case the pinus), considering that when reaching the top of the population of the highest plants.…”

Efficiency of the Use of Yerba Mate Solar Radiation in Intercropping or Monocropping for the Accumulation of Carbon

-The efficiency of solar radiation conversion is a variable often used in crop growth simulation models in which the production of biomass and, consequently, carbon accumulation are related to the conversion of radiant energy into chemical compounds by plants through the process of photosynthesis. The goal of this study was to determine the efficiency of conversion of intercepted photosynthetically active radiation (PARi) into carbon accumulation in shoots of Ilex paraguariensis in intercropping (Ilex paraguariensis A. St. Hil. and Pinus elliottii Engelm) and monoculture. The conversion efficiency of PAR in accumulated carbon was calculated based on the ratio between the accumulated carbon and the PARi involved in the process. Our results demonstrate that the higher conversion efficiency (b) of photosynthetically active solar radiation intercepted in carbon in yerba mate sprouts was obtained in the intercropping scenario.Keywords: Ilex paraguariensis; Photosynthetically active radiation; Intercropping. EFICIÊNCIA DO USO DA RADIAÇÃO SOLAR DE ERVA-MATE EM CULTIVO CONSORCIADO E SOLTEIRO PARA O ACÚMULO DE CARBONORESUMO -A eficiência de conversão da radiação solar é uma variável frequentemente utilizada em modelos de simulação do crescimento das culturas, pois a produção de biomassa, e consequentemente, o acúmulo de carbono, estão relacionados com a eficiência de conversão da energia radiante em química pela planta, através do processo da fotossíntese. Dessa maneira, o objetivo deste trabalho foi determinar a eficiência de conversão da radiação solar fotossinteticamente ativa interceptada (RFAi) no acúmulo de carbono na parte aérea de Ilex paraguariensis, em cultivo consorciado (Ilex paraguariensis A. St. Hil. e Pinus elliottii Engelm) e solteiro. A eficiência de conversão da RFAi em carbono acumulado foi calculado a partir da relação entre o acúmulo de carbono e a RFAi envolvida. A maior eficiência de conversão (b) de radiação solar fotossinteticamente ativa interceptada no acúmulo de carbono na parte aérea em plantas de ervamate é obtida no sistema de cultivo consorciado.Palavras-chave: Ilex paraguariensis; Radiação fotossinteticamente ativa; Consórcio. 984Revista Árvore, Viçosa-MG, v.40, n.6, p.983-990, 2016 CARON, B.O. et al.
