“…It was shown that spermidine concentration was significantly decreased at 38 °C compared with 30 °C in both years of the study, while spermine was also significantly decreased in 2007 and numerically lower in 2008. Similar findings have been reported in apple ( Malus domestica L.) where an increase in temperature 6–7 weeks after flowering reduced the content of spermidine and putrescine, but not spermine (Zhu et al. 1999).…”

Polyamines have been shown to stimulate fruit set and the initial phase of fruit development in several crops. The effect of exogenous application of putrescine on ovary development and seed set of cotton under high temperature stress was investigated under controlled environmental conditions. Putrescine was applied to floral buds of cotton, 24 h prior to anthesis, and caused a significant increase in putrescine content of cotton ovaries collected at anthesis compared with the control treatment. However, there was no increase in spermidine and spermine. High temperature (38 °C) significantly decreased the spermidine content of cotton ovaries in both years of the study compared with the untreated control (30 °C). Spermine was significantly decreased in the high temperature treatment the first year of the study; however, this result was not consistent for the second year. Ovarian putrescine concentration was not affected by the high temperature treatment. Increased temperatures in this study decreased seed set in cotton flowers; however, exogenous application of putrescine ameliorated the negative effect of high temperature on seed set, as expressed by the number of seeds per cotton boll. This was evident in both years of the study. Exogenous application of Putrescine increased the level of putrescine in cotton flowers, which was associated with increased seed set despite the negative effect of increased temperature.

“…Caffaro et al 11 proposed that polyamines might be part of a complex mechanism involved in flowering signal. An intimate connection between polyamines and floral development makes it possible to establish some physiological or biochemical markers using the individual polyamine, the ratios or the total polyamines 69,94 . High levels of Spd and Spm and low Put are associated with flowering of hazelnut trees, whereas the reverse trend is related to dormancy initiation 68 .…”

Polyamines, including putrescine (Put), spermidine (Spd) and spermine (Spm), are polycationic compounds of low molecular weight that are widely distributed in living organisms. They are implicated in a variety of plant processes, such as floral and fruit development. In addition, correlation between polyamines and flower gender or fertility is reported in some plant species. Since polyamines, especially Spd and Spm share a common precursor, S-adenosylmethionine (SAM), with ethylene, they demonstrated competitive effects on functions in fruit development and ripening in many plants. Exogenous polyamines have been employed to regulate floral and fruit development and ripening in a lot of plants. Besides, polyamines have shown their potential for postharvest fruit management. Therefore, in this review, we focused on the involvement of polyamines in floral and fruit development along with perspectives of polyamine research.

“…The long‐chain PAs (Spd and Spm) were dominant in all the periods studied. The literature has reported increases in Spd and Spm associated with flower development, and Spd was defined as a marker of floral induction (Applewhite et al 2000, Huang et al 2004, Kakkar and Rai 1993, Tiburcio et al 1993), while Spm was directly linked to the last stages of flower development, as well as to the increase of temperature required for floral expression (Zhu et al 1999). On the contrary, Put was found to be less important and its content decreased during floral bud development from September to February.…”

The ability to control the timing of flowering is a key strategy in planning the production of ornamental species such as azaleas; however, it requires a thorough understanding of floral transition. DNA methylation is involved in controlling the functional state of chromatin and gene expression during floral induction pathways in response to environmental and developmental signals. Plant hormone signalling is also known to regulate suites of morphogenic processes in plants and its role in flowering-time control is starting to emerge as a key controlling step. This work investigates if the gibberellin (GA) inhibitors and chemical pinching applied in improvement of azalea flowering alter the dynamics of DNA methylation or the levels of polyamines (PAs), GAs and cytokinins (CKs) during floral transition, and whether these changes could be related to the effects observed on flowering ability. DNA methylation during floral transition and endogenous content of PAs, GAs and CKs were analysed after the application of GA synthesis inhibitors (daminozide, paclobutrazol and chlormequat chloride) and a chemical pruner (fatty acids). The application of GA biosynthesis inhibitors caused alterations in levels of PAs, GAs and CKs and in global DNA methylation levels during floral transition; also, these changes in plant growth regulators and DNA methylation were correlated with flower development. DNA methylation, PA, GA and CK levels can be used as predictive markers of plant floral capacity in azalea.
