Fig. 3From: Source–sink manipulations differentially affect carbon and nitrogen dynamics, fruit metabolites and yield of Sacha Inchi plantsSeasonal variations in the percentage of fruit set (means±SD; n = 10) in P. volubilis plants in response to defoliation and defloration. a female flowers were tagged in late Nov. 2016. b female flowers were tagged in Jan. 2017. The values with different letters within the same season denote significant difference at P < 0.05 level. CK, control; ns, no significance. * P < 0.05; **P < 0.01; ***P < 0.001Back to article page
