“…As with others, we detected many interactions: genotypeÁPGR treatment (Meijon et al 2009;Larcher et al 2011), genotypeÁsubstrate mixture (Herna`ndezApaolaza et al 2005Larcher & Scariot 2009;Ameri et al 2012) and PGR treatmentÁsubstrate mixture (Larcher et al 2011). We also found three-way interactions, as did Larcher et al (2011).…”

Potted camellias tend to grow more than desired and sometimes in association with poor flowering. Growth regulators of the triazole group have been successfully applied to overcome these issues in the past; however, recent restrictions on the group indicate that new growth retardants must be considered and tested. Concurrent with this change is the need to reduce the horticultural use of peat (potting mixture), a world resource being quickly depleted. Given these two aims, we evaluated the efficacy of flurprimidol, in combination with three peat alternatives (reused nutshells, rice husk, coconut fibres), to control the growth of four Camellia japonica cultivars. Results showed that all considered peat alternatives, especially rice husk, were suitable as partial substitutes. Results also showed that at low concentrations, flurprimidol controlled height (12Á13% reduction) and enhanced flowering (three flowers per plant vs two). However, we suggest that the growth regulator input be adjusted based on the cultivar and substrate type, as the three factors interact strongly.

“…During floral bud differentiation, conjugated PAs accumulated and became the predominant form until crown formation, consistent with the findings of Aribaud and Martin-Tanguy (1994). The important role of conjugated PAs during floral bud differentiation has been assessed by researchers, for example, high content of conjugated PAs were associated with the onset of floral bud differentiation and floret primordia formation (Dumas et al, 1981); in a study of azaleas, the vegetative bud contained mostly free PAs while floral buds showed higher content of conjugated forms (Meijón et al, 2009); furthermore, the appearance of conjugated PAs, previously shown to be markers of flowering (Martin-Tanguy, 1985), the same with our experimental results.…”

This study was carried out to investigate the relationship between endogenous polyamines (PAs) and floral bud differentiation in chrysanthemum (Chrysanthemum morifolium). In this study, PA content (free, bound, and conjugated) in apical buds, leaves, and roots changed appreciably during floral bud differentiation. PAs accumulated during series of processes such as floral induction, differentiation of floret primordia, and crown formation in apical buds; changes in PAs in apical buds may have a relationship with those in leaves and roots. The levels of free PAs and conjugated PAs [putrescine (Put) and spermine (Spm)] in apical buds rapidly increased during the initiation stage of floral bud differentiation, while free and conjugated spermidine (Spd) reached their highest levels at the stage of floret primordium differentiation. In the free, conjugated, and bound PA fractions, the changes in Spm content were negligible compared to those of Put and Spd throughout the experiment. These findings indicate that PAs participate in regulating the process of flower bud differentiation in chrysanthemum.

“…Cycocel and B-nine are commonly used in height control of poinsettia, which inhibits the synthesis of ent kaurene; an early step in gibberellic acid biosynthesis pathway which is catalized by the enzyme ent kaurene synthesis Meijon et al, (2009). Latimer (2001 has given 1500-3000 ppm and 5000 ppm as the best levels of cycocel and B-nine respectively for poinsettia production.…”
