Crown profiles of selected rowan trees growing under lower (below the 1st decile; a,b,e,f) or higher (below the 9th and above the 8th deciles; c,d,g,h) canopy openness (C_Open); a-d exhibited higher fruit yield (above 2000 n/yr) and e-h exhibited lower fruit yield (below 1000 n/yr); dashed lines represent crown centers and solid lines represent stem position below live crown, blue arrows denote the size and direction of tree asymmetry; the letters correspond to insets in Fig.\ref{682352}; note architectural similarities between b vs. g, and d vs. f
