Resumo: |
The rose is the flower most traded in the world, and Ceará has been outstanding in their production in greenhouses. However, virtually all the production techniques employed by growers are based only on field observations, without any scientific basis. The objective of this study was evaluate the influence of substrate and added with nutrient solution in the rooting of cuttings roses, variety Carola, propagated in plastic trays by the method of cutting (or striking), and evaluate their productivity in greenhouses. The experiment was conducted in the municipality of São Benedito - CE, in the company CeaRosa Com Exp Imp. e Prod. Flowers Ltda. in its early seedling production, and in the TecFlores - School of Floriculture of the State Government of Ceará in its early planting in the greenhouse. Were also evaluated six substrates (100% sand, 100% dry coconut fiber, 50% sand + 50% dry coconut fiber, 75% dry coconut fiber + 25% sand, 25% dry coconut fiber + 75% sand and 25% husk rice + 75% dry coconut fiber). The experimental design was factorial analysis with two factors, and the parameters evaluated were added with nutrient solution and the six substrates. At the stage of seedling production was evaluated the percentage of catches of seedlings, root length, seedling dry weight and content of macro and micronutrients present in seedlings. In the production phase and development in the greenhouse, were assessed the number of sprouts emitted by plants and the levels of macro and micronutrients of the leaf tissue of plants. The added with nutrient solution was not affect the percentage of catches of the seedlings, regardless of the substrate, but was affect the root length and dry weight of seedlings. The productivity of the rose plants was not affected by the substrate or by added with nutrient solution during the rooting process. |
