Abstract
The total of three consecutive years of fruit production was evaluated in six coffee cultivars (<em>Coffea arabica L</em>.) propagated by seed and grafted onto Robusta (<em>Coffea canephora</em> var. Robusta). The plantations were established at 640 m, 920 m, and 1340 m altitude in the central region of the Veracruz State, Mexico. The <em>coffea</em> plants were established in soils naturally infested with nematodes. Grafted plants had higher production than those propagated by seed. Fruit production was higher at 640 m and 920 m than at 1340 m for the two types of propagation. The cultivars Colombia Brote Café and Colombia Brote Verde had the highest fruit yield regardless of the propagation methods; in contrast, Pacamara, had the lowest. The grafted coffee plants that were planted at 1340 m had a yield reduction of 27% in comparison with those at 640 and 920 m. When the Costa Rica 95 variety was grafted, it achieved fruit yield similar to Colombia Brote Verde and Colombia Brote Café. Pacamara produced almost 28% more fruit when it was grafted onto Robusta.
Highlights
Nematodes are worm-like invertebrate and unsegmented animals that attack coffee plantations around the world and severely reduce fruit production
The experimental material consisted of the Coffea arabica L. cultivars Colombia Brote Verde, Colombia Brote Café, Pacamara, Costa Rica 95, Garnica F5, and Aztec Gold obtained of seed germination as well as grafted onto Coffea canephora Pierre ex Froehner (Robusta coffee)
WAMATU et al (2003) indicated that variations in fruit production between coffee cultivars with adequate crop practices are mainly influenced by the environment
Summary
Nematodes are worm-like invertebrate and unsegmented animals that attack coffee plantations around the world and severely reduce fruit production. Rootstocks have been used to control nematode attack in coffee production fields (ZHANG & SCHMITT, 1995); they offer environmental advantages over the application of nematicides to the soil (VILLAIN et al, 2000). Most C. canephora rootstocks are propagated by seed, and this species is cross-pollinated (ETIENNE et al, 2002). There are clonal rootstocks of Robusta like the cv. Nemaya (ETIENNE et al, 2002) that tolerate root damage from Meloidogyne and Pratylenchus or the cv. Commercial coffee production usually uses seedlings because of their low cost (ETIENNE et al, 2002). In Mexico, clonal rootstocks of Robusta are not used commercially, and they have not yet been certified or registered
