A review of the importance of spines for pejibaye heart-of-palm production
Commercial plantations of pejibaye (Bactris gasipaes Kunth, Palmae) are expanding in tropical America to supply the heart-of-palm market. The heart-of-palm is a gourmet vegetable composed of the tender unexpanded leaves in the palm's crown. Both spiny and spineless germplasm is available to growers,...

Commercial plantations of pejibaye (Bactris gasipaes Kunth, Palmae) are expanding in tropical America to supply the heart-of-palm market. The heart-of-palm is a gourmet vegetable composed of the tender unexpanded leaves in the palm's crown. Both spiny and spineless germplasm is available to growers, but there are no clear data on the superiority of either. Comparisons made among populations, among progenies within populations or among alleles within progenies are of interest for different reasons.
