Cloning of erect, thornless, non-browsed nitrogen fixing trees of Haiti's principal fuelwood species (Prosopis juliflora)

摘要

A progeny trial in Haiti compared 70 open-pollinated families ofProsopisrepresenting seed sources from Haiti, Peru, Chile, Argentina and southwestern US. At the end of 4 years growth, the tallest 6 families were of Peruvian origin. Some of these Peruvian trees (probablyP. juliflora) were thornless, had erect habit and were non-browsed by goats, unlike other thornlessProsopis albafamilies from South America. Scions from the 5 tallest spineless and most erect trees were transported from Haiti to Texas AI University where they were successfully grafted ontoP. albarootstock. These scions should have great potential for grafting onto existing weedyProsopisand for grafting onto rootstock previously shown to tolerate salinities of seawater and pH values of 10.3.
