Evaluation of Gypsophila paniculata L.
growth using hydroponics.
The experiment was carried out in a greenhouse,
in the campus of the Universidade Federal de
Viçosa using hydroponics to study the behavior of
the Gypsophila paniculata L. during its cycle in 6
periods of harvest (60, 75, 90, 105, 120 and 135 days
of plant age). The plants were growth under hydroponic
with recirculation of nutrient solution on expanded
clay substract. A completely randomized experimental
design with 6 treatments and 4 replications
was used. Each plot consisted of one of the 6
harvest date. Immediately after harvesting, the whole
plant was divided into roots, shoots, leaves and inflorescences
in order to determine the fresh and dry
matter to evaluate the growth of each organ and of
the entire plant. Plant height and the number of leaves
were also recorded in order to evaluate plant growth
too. The cuttings were transplanted, aging 30 days
and the last harvest occurred at 11/01/95-105 days,
corresponding to the first flowering cycle. The total
cycle was concluded with 135 days. The flowering
initiation occurred about the 90th day of age. The
development of the species in hydroponic was considered
good, with an average of 2.6 very good quality
commercial stems per plant. The production of
fresh and dry matter was crescent during the entire
cycle as well as the height.The highest growth rate
was noticed around the age of 98 days.
