VIANA, Thales VA et al. Planting density and number of drains influencing the productivity of rose plants cultivated in pots. Hortic. Bras. [online]. 2008, vol.26, n.4, pp.528-532. ISSN 0102-0536.  http://dx.doi.org/10.1590/S0102-05362008000400021.

The cultivation of flowers in Ceará State has expanded during the last years, especially in highland areas with a favorable climate for several crops. However, there exist only limited research in this area, so that producers work empirically with those crops. Consequently, this research aimed to evaluate the effects of the number of plants (2, 3 and 4) and the amount of drains (1 and 8) per pot on the number of stems per pot, in a protected environment. The experiment was carried out in São Benedito, Ceará State, Brazil, following a 3 x 2 factorial randomized block design with four repetitions. The number of stems with 35, 40, 50, 60 cm and, the total number of stems per pots of 12.0 L were evaluated. The highest number of plants per pot provided the greatest number of stems per pot, but with a predominance of lower commercial value. On the other hand, the least number of plants per pot resulted in few stems per area which were better evaluated commercially. The use of pots having more drains reduced the total number of stems per pot.
