Figure 2.1
Distribution of shade,light,fruit size and fruit colour in
large and small apple trees. (1) Bush trees of 'Cox's Orange Pippin'
on a semi-dwarfing (a) and a dwarfing (b) rootstock showing leaf
areas at different distances from the trunk and ground (measured in
half metre grid cubes) and leaf area indices (LAIs) summed vertically.
The solid line gives the boundary within which apple fruit weight did
not exceed 80 g,the broken line the inner boundary of the zone in
which,on average,more than 25% of the surface was red. Taken from
Jackson (1970). Reproduced with permission from Blackwell
Science. (2) Hedgerows of 'Jonathan' on 'M.9' and 'M.2' rootstocks in
section showing (A) light intensity (B) fruit size in each position and
on average and (C) percentage of well-coloured fruits in each
position and on average. Each grid side is 0.5 m. Reproduced from
Verheij and Verwer (1973) with permission from Elsevier Science.
