BERMUDA GRASS FOLIAR CHLOROPHYLL CONTENT INFLUENCED BY LUMINOSITY AND SUBSTRATE
Abstract
The objective of this work was to evaluate the influence of luminosity and different substrates on Bermuda grass (Cynodon dactylon x C. transvaalensis) chlorophyll a and b contents and root system evaluation. The experiment was conducted in a 5 x 4 factorial scheme (substrates x luminosities), in completely randomized design with 20 treatments and 3 replicates. The substrates were: S1 = Soil, S2 = Soil + sand (2:1), S3 = Soil + organic matter (1:1), S4 = Soil + organic matter + sand (2:1:1) and S5 = organic matter + sand (3:1), in four luminosity conditions: full sun, 30%, 50% and 80% of shading for six months. We evaluated chlorophyll a and b. After 180 days after planting, bigger contents of both chlorophyll were found according to increment of shading.
