1 4 Peach palm. Bactris gasipaes Kunth The fruit is a drupe, usually shiny orange, red or yellow (Fig. 5), and may have superficial striations. The tip of the fruit may be mammiform, rounded, angular or truncated. Dimensions are quite variable: length 2-7 cm, width 2-8 cm and weight 4-186 g. Colour of the mesocarp varies from creamy white to orange. The number of mature fruits per inflorescence (commonly referred to as raceme or bunch) varies from 0 to 764, with total fruit weight 0-20 kg. Parthenocarpic fruits are common (average 21 per raceme) and generally slightly smaller than fertile fruit. The dark endocarp, containing the seed, is usually located centrally in the fruit, but may occur at the distal end. The endocarp varies considerably in shape and dimensions: ovoid, elliptic, round, oblong or cuneiform; length 1-4 cm, width 1-2 cm, weight 1-9 g. The endocarp has three pores, two usually above the equator and the third (the germ pore) farther away; it generally has flattened fibers on its surface, and these may be free from or adhere to the mesocarp. Seeds are recalcitrant and rapidly lose viability when dried (Ferreira and Santos 1992). Germination is hypogeal. In peach palm, the endocarp with its enclosed seed is commonly known as the ‘seed’. Although not technically correct, this common usage of the word seed will be followed in the text. The embryo produces a shoot and radicle, and the radicle is soon replaced by adventitious roots arising from the obconical seedling axis (Tomlinson 1990). 3.2 Ecology Cultivated peach palm is adapted to a wide range of ecological conditions, reflecting its wide geographical distribution in the humid tropics of Latin America. It is most productive on relatively deep, fertile, well-drained soils at low to middle altitudes (
