affect leaf function, apple leaves can tolerate a minor reduction in functional leaf area without reducing Pn. Physical removal of up to 10% of spur leaves did not reduce Pn ( Hall and Ferree, 1976 ). In this experiment, visual estimates of leaf injury by

mechanical harvesting, it was proven difficult to facilitate mechanical management, such as dormant pruning ( Kurtural et al., 2012 ) and shoot removal ( Terry and Kurtural, 2011 ), with some success in mechanical leaf removal ( Cook et al., 2015 ; Yu et al

abscission in apple when photosynthate reserves are depleted. Partial defoliation has also been shown to affect whole tree Pn ( Ferree and Palmer, 1982 ) and fruit set ( Llewelyn, 1968 ) in apple. Dormant spray oils have been shown to reduce Pn in apple

Fumariaceae ( Liden et al., 1997 ). The former Latin name, Dicentra spectabilis , translates as “spectacular two spurs,” while Lamprocapnos means “bright smoke,” both referring to the flowers. It is a spectacular flower known for at least 2000 years for its
