“…Fresh weight in 'Perfecta' was highest among the three varieties. Our results confirm other studies that indicated that parameters of inflorescence architecture or fresh weight depend on environmental conditions (i.e., temperature, photosynthetic photon flux, supplemental lighting), varieties, and application of plant growth substances (Davies et al, 1996;Doi et al, 1989;Hayashi et al, 1992;Hicklenton, 1986;Hicklenton et al, 1993;Shlomo et al, 1985). Figure 3 plots parameters of architecture against fresh weight grown under four densities in 'New Face'.…”

“…One crucial determinant of filler flower quality is having clusters of multiple florets. This characteristic is decided by inflorescence architecture such as the total number of florets, number of branches, and branch length, however, understanding inflorescence architecture is difficult because the numbers of florets and branches per cut flower depend on environmental conditions and varieties (Doi et al, 1989;Hayashi et al, 1992;Hicklenton, 1986;Hicklenton et al, 1993;Shlomo et al, 1985). Moreover, particular inflorescence architectures have complex relationships with each other.…”

The effect of plant density and variety on allometry in Gypsophila paniculata L. was studied. Increasing plant density significantly reduced fresh weight, total branch length (the sum of the lengths of all primary branches), number of dichasia, number of florets per dichasium, and total number of florets in cut flowers in 'New Face'. The relationships between fresh weight and the total branch length, number of dichasia, and total number of florets were negatively allometric, isometric, and positively allometric, respectively. There were allometric relationships between fresh weight and the number of dichasia, number of florets per dichasium, and total number of florets on each branch order. The allometric exponents of regression relating the number of dichasia and the total number of florets to fresh weight increased from lower-to higher-order branches. On the other hand, the allometric exponents of regression relating the number of florets per dichasium to fresh weight were similar in almost all orders. Significant differences were found in fresh weight and parameters of inflorescence architecture among varieties grown under identical plant density. Allometric exponents relating the total branch length and number of dichasia to fresh weight, varied, and those relating the total number of florets to fresh weight were stable among varieties grown under identical plant density.
