Abstract

FREITAS, Kellem; TEIXEIRA, Walquíria; FAGAN, Evandro  and  SOARES, Jérssica. Tibouchina granulosa Adaptation Under Aluminum Application. Floresta Ambient. [online]. 2017, vol.24, e20160114.  Epub Apr 27, 2017. ISSN 1415-0980.  http://dx.doi.org/10.1590/2179-8087.011416.

This study aimed to evaluate the adaptability of Tibouchina granulosa aluminum application. The experiment was conducted in growth chamber using randomized blocks with 5 treatments (0 mg, 8 mg, 32 mg, 64 mg and 128 mg L-1 of aluminum) and 7 repetitions. The plants were influenced by the application of aluminum in the first 30 days after application, being observed a reduction of photosynthetic pigments. However, 45 days after the treatments was observed positive effect of aluminum, also observed that the application of 8 mg L-1 gave the increase of 34%, 71%, 56% and 35% chlorophyll content a, b total and carotenoids, respectively, compared to the control treatment. Therefore, Tibouchina granulosa plants adapted to the aluminum application, also showing that this species may possibly be used in areas of reforestation projects where the soil has high concentrations of aluminum, such as the cerrado soils.
