  abstract = {{L}arge differences in seed desiccation sensitivity have been observed previously among ten coffee species (#{C}offea arabica$, #{C}. brevipes$, #{C}. canephora$, #{C}. eugenioides$, #{C}. humilis$, #{C}. liberica$, #{C}. pocsii$, #{C}. pseudozanguebariae$, #{C}. sessiliflora$ and #{C}. stenophylla$). {O}f these species, #{C}. liberica$ and #{C}. humilis$ were the most sensitive to desiccation and #{C}. pseudozanguebariae$ the most tolerant. {A} study was carried out using the same seed lots to investigate if these differences in desiccation tolerance could be correlated with differences in soluble sugar content. {S}oluble sugars were extracted from dry seeds and analysed using high performance liquid chromatography. {T}he seed monosaccharide (glucose and fructose) content was very low (1.5 to 2 mg/g dry weight (dw)) in all species studied. {T}he sucrose content ranged from 33 mg/g dw in #{C}. liberica$ seeds to 89 mg/g dw in seeds of #{C}. pocsii$. {R}affinose was detected in the seeds of only five species (#{C}. arabica$, #{C}. brevipes$, #{C}. humilis$, #{C}. sessiliflora$, #{C}. stenophylla$), among which only three species (#{C}. arabica$, #{C}. sessiliflora$ and #{C}. brevipes$) also contained stachyose. {B}oth raffinose and stachyose were present in very low quantities (0.3-1.4 mg/g dw and 0.1-0.7 mg/g dw, respectively). {V}erbascose was never detected. {N}o significant relationship was found between seed desiccation sensitivity and : (i) the sugar content ; (ii) the presence/absence of oligosaccharides ; and (iii) the oligosaccharide:sucrose ratio.
