Conteúdo: | For more than two hundred years, sugar cane was grown extensively in Puerto Rico, occupying thousands of hectares. However, sugar cane became an unprofitable industry and alternatives for the use of  land are necessary. On the south coast, which is the driest area of Puerto Rico, much of the land formerly devoted to sugar cane production now stands idle. Guavas (Psidium guajava) are an alternative for the south coast growers. The guava originated in the American tropics. The Aztecs named it Xalxocotl. It is known as goyabe in French, guajava in German, goiaba in Portuguese and aracá o guacú in Brazil (Toro-Toro, 1993). Wilson Popenoe suggested that it originated in Haiti (Toro-Toro, 1993). Today, it is commercially grown in South Africa, Taiwan, the French Antilles, Hawai, Florida, California, Brazil, Mexico, and other parts of the world. The guajava tree is small (up to 6 m high) with a broad spreading top, branching freely close to the ground. It has opposite, oblong leaves, seven to 18 cm in length, with prominent veins. The flowers are white, about 2.5 cm in diameter, borne in axils of leaves of recent growth. The fruit may be round, ovoid or pear shaped. It may weigh from 28 to 454 g. The skin color is usually light green. The flesh may range from white, yellow, pink to red. Flavor may range from sweet to highly acidic. It has a distinctive aroma, which may range from mild and pleasant to strong and penetrant (Le Bourdelles and Estanove, 1967; Toro-Toro, 1993). It may be susceptible to various pests and diseases (Vargas, 1974) throughout its range, which encompasses the whole tropical world.
