In 2010, trees underwent mid-height pruning (low-cutting pruning), bananas 5.0 x m. years later, palm seedlings same as plants, 5 3 Five experimental units randomly selected each system. evaluated variables included chlorophyll indexes (chlorophyll a, b, total chlorophyll, a/b ratio) gas exchange parameters (net CO2 assimilation rate, stomatal conductance, intercellular concentration, transpiration, intrinsic water use efficiency, instantaneous carboxylation efficiency). Regarding indexes, differences observed only monoculture displaying highest values. terms exchange, exhibited lower values higher conductance transpiration. net rate intercropping, while efficiency found monoculture. summary, showed most related activity, followed by banana, which stood out achieving rate.
