Inflorescence Development and Composition of Gypsophila paniculata L. 'Bristol Fairy'.

Effect of Plant Density and Variety on Allometry of Inflorescence Architecture in Gypsophila paniculata L.

“…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'.…”

“…In G. paniculata, the cut flower is an aggregate of dichasia and each dichasium is formed of florets (Hayashi et al, 1992) (Fig. 1).…”

“…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.…”

Path Analysis of Interrelations of Some Components Determining the Number of Florets per Shoot in Gypsophila paniculata L.

“…paniculata L. is composed of compound inflorescence and forms panicles, which have dichasia as the constitutional units (Hayashi et al, 1992). The volume of the panicle is determined by the number of branches and the number of florets per dichasium that develop on branch tips; however, it is unclear what factors affect these numbers during the cultivation process and therefore influence cut flower quality.…”

Far-red Light Supplemented with Weak Red Light Promotes Flowering of Gypsophila paniculata

“…Cut flower quality of G. paniculata is affected by plant density and growth period (Fudano et al, 2007;Hayashi et al, 1992Hayashi et al, , 2009. In these studies, cut flower length and weight were determined with the number of units and florets to evaluate cut flower quality, and stem diameter was found to have strong effects on some determinants of cut flower quality.…”
