  abstract = {{T}he coffee tree is an important economic plant for several developing countries. {S}tem and leaf dry biomass, which are key traits of plant production, are used in functional-structural plant models to simulate plant growth and predict yield. {T}hese values are difficult to obtain since they classically rely on time-consuming protocols and require destructive measurements. {M}easuring stem and leaf dimensions (length and width) to estimate them provides a non-destructive and rapid approach for use in the field. {I}n this study we sought the best allometric relationships existing between stem and leaf dimensions and their corresponding dry mass in order to avoid destructive measurements which are also time-consuming. {T}his was investigated in three coffee species: {C}offea canephora, {C}offea liberica var. liberica and {C}offea liberica var. dewevrei in {I}vory {C}oast. {F}or each species, the internodes and leaves of three axis categories (stem, branch and branchlet) comprising the main compartments were sampled. {T}wo different equations were found to estimate the stem and leaf dry mass whatever the species and the axis categories: (1) a linear equation for the relation between the stem volume ({V}) and its corresponding dry mass ({IW}e), {IW}e = 0.70 x {V} and (2) a power law for the relation between the leaf area [as the product of length ({LL}) and width ({W}i)] and its dry mass ({LW}e), {LW}e = 0.007 ({LL} x {LW}i)(1.02). {F}inally, stem and leaf dry mass could be easily obtained without destructive measurements. {T}his method could be applied to estimate the plant total leaf area and the total stem and leaf biomass of a plant in an agroforestry system.},
