Abstract: The objective of the present study was to evaluate the effect of the irrigation water salinity on the initial growth of Tectona grandis plants. The work was carried out in a greenhouse with 100% solar radiation interception at Goiás State University, Ipameri Campus, Brazil. The Tectona grandis seeds were sown in eight-liter pots containing a mixture of soil, sand and manure at ratio 3:1:0.5, respectively. At 100 days after germination, the plants were irrigated daily with water of different electrical conducti… Show more

“…The lower electrical conductivity limited CO2 inflow, photosynthesis and biomass accumulation. Stomata control by tree plants to minimize water loss underwater shortage or salinity has been reported by several authors (Duarte, Rocha, De Lima, Matos & Rodrigues, 2016;Freitas et al, 2017;Matos et al, 2016) The low Si percentage in the leaves and roots of Eucalyptus urocam plants was indicative that this species does not accumulate this nutrient, but it was possible to verify that the accumulation in roots and leaves was much bigger in plants irrigated with non-saline water. The lower percentage of sodium in the leaves and roots may be related to the beneficial effects of Si (Table 2).…”
