RESUMO

The cultivation of tropical flowers is being highlighted in many areas of the country, recognized as an important alternative to the diversification of the production, once assists to the needs of the small rural properties with a good use of the familiar labor. The objective of this work was to evaluate the cultivation of the torch ginger in different planting distances in the North of Paraná State. The experiment was accomplished at the Centro de Ciências Agrárias of the Universidade Estadual de Londrina. Plants of the pink torch ginger were used, obtained from in vitro propagation. The planting was made with seedlings with 18 months of age and medium height of 80 cm. The distances measures used for the planting were: 2.0 x 2.0 m; 2.5 x 2.0 m and 3.0 x 2.0 m, that constituted three treatments in randomized blocks. Sixteen months after the planting, the evaluations began through biweekly crops, being appraised the following parameters: number of inflorescences, length and diameter of the floral stem, total diameter and diameter of the central button of the inflorescences and length of the inflorescences. Besides these evaluations, in November of 2008/2009, the counting of the number of vegetative stems was accomplished by clump and in November of 2009, it was evaluated the measurement of the area per clump and the maximum height reached by the vegetative stems. The data were submitted to the analysis of variance and the averages, compared by the test of Tukey to 5% of probability. The production data were compared by test of Scott- Knott to 5% of probability. After two years of evaluation, it was observed that there was not influence of the different planting distances in the morphologic characteristics of the inflorescence, except for the diameter of the floral stem, that presented in the first year of crop superior averages in the plants far 3.0 meters each other and for the area of occupation of the clumps that was larger in the spacing of 3.0 meters in relation to the plants with 2 meters of distance. In the second year, the diameter of the floral stems didn t present differences between the plants with 2.0 and 3 meters of distance, being however, superiors in relationship to the inflorescences produced in the spacing of 2.5 meters. In the three evaluated distances, there was an increase of the production between the first and second year of crop, with larger production observed in the plants distant 3.0 meters each other. The inflorescences achieved a commercial pattern and although a reduction in the production has happened during the coldest months, it configures an option that doesn t demand great investments in structure, that can be done under open sky, inasmuch as irrigated and complemented with the production of other ornamental species in the period of low production.
