Abstract

Palm

heart production was evaluated at the ages of 11, 12 and 13

months in four varieties. Three of those varieties were

thornless (Diamantes-1, Diamantes-10 and Diamantes-20)

the other one had thorns in the trunk (Utilis-Tucurrique). The

trial was conducted in Guapiles, Costa Rica. The parameters

evaluated were: earlinesss; number of stems harvested;

sheath lengths of the leaf previous-to-the emerging.leaf and

of the emerging leaf; lengths of the petiole and leaf lamina;

lengths of the foliar and caulinar heart of palm; weights of the

foliar and caulinar hearts of palm; diameters of the foliar and

caulinar heart of palm; and industrial yield (boxes/ha). The

varieties Diamantes-10 and Diamantes-20 were superior in

earliness and number of stems harvested. At the age of 12

months the number of stems harvested per hectare were:

7067, 4493, 4381 and 2370 respectively for the varieties

Diamantes-10, Diamantes-20, Diamantes-1 and Utilis-

Tucurrique. The average weight per stem of foliar and

caulinar heart of palm respectively was 226.67g and 397.57g

per stem for Diamantes-20; 208,91g and 379.04g for

Diamantes-10; 169.47g and 264.62g for Diamantes-1; and

124.81g and 122.01g for Utilis-Tucurrique. The thornless

varieties produced a much larger caulinar heart of palm than

the thorny variety, mainly Diamantes-20 and Diamantes-10.
