Gypsophila paniculata is a cutting flower that belongs to the Caryophyllaceae family. Known popularly as 'mosquitinho' it is marketed for making arrangements and bouquets. The sexual propagation results in disuniform plants because of the genetic segregation. On the other hand, the vegetative propagation allows dissemination of plant pathogens when infected plants are used. Through the micropropagation technique it is possible to obtain the heterose fixation and pathogen free young plants on a commercial scale. In vitro rooting was analyzed in Gypsophila paniculata plants at different periods of cultivation. Fresh and dry aerial and rooting matter were evaluated at 4; 8; 12; 16; 20 and 24 days. The experimental units were arranged according to a randomized block design with six replicates, each replicate being a pot with five plants. The data were submitted to variance and regression analysis. The results allowed to conclude that both shoot and root growth were progressive along the rooting days. Root primordial appeared after eight days in the rooting media.
