Pruned trees had approximately one-fourth of the center of the canopy removed during March. Penetration of PPF was generally greater in canopies of pruned trees than in non-pruned trees during each season. There was no difference in W3 between pruned and non-pruned trees at any measurement period. Total leaf chlorophyll content was greatest for pruned trees during November, but similar for pruned and non-pruned trees during April and July. During the year that the pruning treatment was imposed, there was no significant effect of pruning on fruit color. aMangifera indica L aPhotosynthetic photon flux1 aGAYE, G.
