Comparative palm heart production among four varieties of peach palm (Bactris gasipaes Kunth).
Palmheart production was evaluated at the ages of 11, 12 and 13months in four varieties. Three of those varieties werethornless (Diamantes-1, Diamantes-10 and Diamantes-20)the other one had thorns in the trunk (Utilis-Tucurrique). Thetrial was conducted in Guapiles, Costa Rica. The parametersevaluated were: earlinesss; number of stems harvested;sheath lengths of the leaf previous-to-the emerging.leaf andof the emerging leaf; lengths of the petiole and leaf lamina;lengths of the foliar and caulinar heart of palm; weights of thefoliar and caulinar hearts of palm; diameters of the foliar andcaulinar heart of palm; and industrial yield (boxes/ha). Thevarieties Diamantes-10 and Diamantes-20 were superior inearliness and number of stems harvested. At the age of 12months the number of stems harvested per hectare were:7067, 4493, 4381 and 2370 respectively for the varietiesDiamantes-10, Diamantes-20, Diamantes-1 and Utilis-Tucurrique. The average weight per stem of foliar andcaulinar heart of palm respectively was 226.67g and 397.57gper stem for Diamantes-20; 208,91g and 379.04g forDiamantes-10; 169.47g and 264.62g for Diamantes-1; and124.81g and 122.01g for Utilis-Tucurrique. The thornlessvarieties produced a much larger caulinar heart of palm thanthe thorny variety, mainly Diamantes-20 and Diamantes-10.
