Interacao entre diferentes tipos de solo e fungos micorrízicos vesículo - arbusculares na producao de mudas de café (Coffea arabica L.)
An experiment was conducted under greenhouse conditions to evaluate the effect of different soil types and vesicular-arbuscular mycorrhizal fungi on the development of coffee-tree seedlings. The experiment had a factorial design and consisted of three sterilized soils (a quartz sand, a dark red latosol and a "Terra Roxa" and four VAM fungi (Glomus macrocarpum, Glomus leptotichum, Gigaspora heterogama and Gigaspora margarita). The plants were harvested six months after transplanting. It could be observed that G. margarita and G. leptotichum, in this sequence promoted a better growth of the plants and higuer absorption of P and K on the two first soils. On the quartz sand neither one of the VAM fungi had a beneficial effect on the plants. The amount of available phosphorus in the soils did not affect mycorrhizal root colonization, although it did influence the efficiency of the symbiosis.
