Production and growth of three gypsophila paniculata clones cultured under identical greenhouse conditions
There clones of Gypsophila paniculata c.v. perfecta were compared in the present research, with the aim of selecting the most efficient and productive propagation material for ou r tropical condition and to determine the genetical or environmental origin of the purple color that sometimes is present during flower development. A Randomized Complete Block (RCB) design was selected, with three replicates,undercommercial growing conditions in an export cutflower industry located in Madrid (Cundinamarca). Highly homogeneous cuttings, original from Balborts, RahamMeristem and Cor van Duyn were used; these were obtained from mother plants grown in there production farms located inthe Sabana of Bogotá (300 cuttings per farm). Forty five days after planting, 522 cuttings were rooted using the comercialmethodology and then planted under commercial greenhouse. The first harvest of flowers in each treatment was programmed according the flower development, continuing until the end of the harvest cycle. The cut flowers werearranged in bunches of 300 grams each. The variables related to plant growth, production and flower quality wereregistered. In the process of rooting, the experimentalresults show differences between clones; the once coming from Cor van Duyn (T3) were more vigorous. In the initial samples, the variables associated with growth (height,stem diameter, number of branches) also differ significantly between clones but at the moment of the first harvest the behavior is similar between them. The duration of the developmental phases was dissimilar between clones; the plants from T1 (Balborts) were precocious in starting stem elongation and production cycle. The clones that showed the shorter vegetative cycle had the largest reproductive phase, and inversely; however, en every case, the total duration in the greenhouse was of 227 days. The production of bunches per plant was different between clones (1.80, 1.72 and1.46 for clones T1, T2 and T3 respectively). These values differ from the reported by the commercial companywhere the experiment was performed (1.2 buches perplant). Theflowers were of excellent quality and no purple coloration in petals was present. It is assumed thatthis trait appears by induction from a not-known environmental effect.
