Resumo: | Different growing media were compared as to water adsorption and water loss, at Jaboticabal, SP, Brazil, through a three-year period. The objective was to recommend substrates other than tree fern fiber for cultivation of epiphytic orchids. Two treatments of each substrate were used in each sampling: materials stored in laboratory (without use) and materials exposed to conditions of orchid cultivation under laths (used). Generally, the substrates without use adsorbed less water than used substrates. When materials without use were compared, the tree fern fiber retained initially the greatest quantity of water and the blocks of pressed coconut bark, the smallest. However, these blocks gained a great capacity of water adsorption after being used. Charcoal added to the growing media did not cause significant alterations in the studied characteristics. In terms of water relations, the best growing media to substitute the tree fern fiber were composed by blocks of pressed coconut bark or by mixtures of this material with charcoal or Eucalyptus grandis bark. Bark of E grandis alone or in mixture with charcoal did not give good results. |

Usaram-se dois lotes de todos os substratos em cada amostragem: armazenados em laboratório (novos) e expostos a condições de cultivo de orquídeas em ripado (usados). Os substratos novos geralmente adsorveram menos água do que os usados. Comparando materiais novos, o xaxim adsorveu, inicialmente, a maior quantidade de água, e os blocos de casca de coco ("coxim"), a menor. 0 "coxim", entretanto, apresentou grande capacidade de adsorção de água depois de usado. A adição de carvão vegetal aos substratos não alterou significativamente as características estudadas. Em termos de comportamento em relação à água, os substratos mais recomendáveis para substituir o xaxim foram "coxim" puro e em mistura com carvão vegetal ou casca de Eucalyptus grandis; os menos recomendáveis, casca de E. grandis pura e em mistura com carvão vegetal.Dep. de Ciências Exatas FCAV-UNESP, Rodovia Carlos Tonanni, Km 5, CEP 14870-000 Jaboticabal, SPDep. de Hortic.
