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.
