Abstract
Of several agronomic treatments imposed on commercial ‘Calypso’ mango orchards with the intent of increasing fruit dry matter content, water denial was selected for repeated experiments in subsequent seasons.
NIR estimated DM and lineal LWT was measured weekly.
A 2-4 week water deficit before harvest increased DM levels by ca. 0.4-1.2% DM units without decreasing fruit size, while longer water denial periods were also associated with decreased fruit size.
The DM% increase in water denied fruit was associated with increased Brix of ripened fruit, without impact on ripening behavior (time to ripen). Additionally it was demonstrated that the NIR-DM model was robust in use across fruit from trees grown under different water stress levels (R2=0.82, RMSEP=0.52).
