The analysis of light interception and leaf area index (LAI) in central leader 'Fuji/M26' apple orchards producing high yields and quality fruit

摘要

The components of tree structure which relate to productivity; fruit number, fruit weight, flowering and fruiting ratio, the number of fruiting lateral branches, LAI and light interception were investigated in well-managed central leader 'Fuji/M26' and 'Jonagold/M26' apple orchards producing quality fruit with high yields. It was suggested that high yields of quality fruit can be attained by increasing the flowering and fruiting ratio of good fruiting lateral branches, but without increasing the number of non fruiting lateral branches.
