The plants were grown and established in different&lt;br/&gt;organic substrates mixes. The substrates resulted from the mix of&lt;br/&gt;compost and charcoal, land of mount and Holm oak bark, and peat and&lt;br/&gt;volcanic tuff. The plants were fertilized with four levels of nitrogen&lt;br/&gt;(0, 10, 30 and 50 mg L-1). Six months after the establishment, 64.84%&lt;br/&gt;to 80.22% of the plants were adapted to the climate conditions. The&lt;br/&gt;highest survival rates in plantlets were obtained in the adaptation&lt;br/&gt;conditions using peat-volcanic tuff and nitrogen doses of 30 and 50 mg&lt;br/&gt;L-1. These plants had an average of 8.01 cm height, 5.15 leafs, 2.66&lt;br/&gt;pseudo-bulbs, 77 to 89 mg of total accumulated dry matter, and 42 to&lt;br/&gt;45% of C in leaves and pseudo-bulbs. The fertilization had a&lt;br/&gt;significant effect (P &lt;= 0.05) on the plants growth and a highly&lt;br/&gt;significant effect (P &lt;= 0.01) on number of leaves, width of the major&lt;br/&gt;leaf and the number of pseudo-bulbs; The interaction substrates and&lt;br/&gt;fertilization had a highly significant effect (P &lt;= 0.01) on the&lt;br/&gt;nitrogen content in leaves and pseudo-bulbs.</style></abstract></record></records></xml>
