  abstract = {{T}he comparison between the cultivar {B}ourbon and its mutant, the {B}ourbon pointu, of {C}offea arabica led to five novel findings on fruit development and three main impacts of the mutation. {C}offea arabica '{L}aurina' ({B}ourbon pointu) is a natural mutant of {C}offea arabica '{B}ourbon'. {R}elative to the '{B}ourbon' cultivar, it is characterized by internode dwarfism, a {C}hristmas tree shape, and lower caffeine content. {T}he effects of the laurina mutation on fructification over time, the fruit structure and seed characteristics were studied here. {F}ruits of '{B}ourbon' and '{B}ourbon pointu' were monitored. {T}he trees were grown in the same plot and flowered on the same day. {H}arvesting was done every 2 weeks from the 6th to the 26th week after flowering. {H}istological observations were carried out using multiphoton and conventional microscopes. {T}he measurements concerned the fruit, parchment and seed. {F}ive novel findings on fructification development were obtained: (1) a sigmoid model and non-linear regression efficiently described the phenomenon; (2) a precise relationship was defined between the qualitative stages of fructification and quantitative observations, thus revealing key weeks in this process; (3) the parchment had a mesocarpic origin; (4) a meristematic zone was present close to the parchment; and (5) an endocarp with three cell layers was visible in young fruits. {T}hree effects of the laurina mutation were highlighted: (1) fruit growth ended 1 week earlier in '{B}ourbon', but without difference in fruit length. {I}n contrast, fruits were wider on average in '{B}ourbon'; (2) the parchment of narrow seeds in '{B}ourbon pointu' was thicker than in other '{B}ourbon pointu' and '{B}ourbon' seeds; and (3) the narrow seed frequency in '{B}ourbon pointu' depended on environmental conditions.},
