Photosynthetic photon flux (PPF), specific leaf density (Wa), and total leaf chlorophyll concentration (Chl) were determined at several positions in pruned and non-pruned mango (Mangifera indica L. cultivar `Tommy Atkins') canopies during April, July and November. 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. |
