“…The regeneration responses of PLBs from explants grown on medium containing different concentrations of PAs (Put, Spd, and Spm) were similar to those of the control treatment (without PAs), so this supplementation to MSM/2 medium is not recommended. PAs can improve plant growth and development because of their effects on cell division and differentiation(Abbasi et al 2017) and these results were observed in this study, with high percentages of PLBs regeneration in apical tTCLs (83.33 to 100%). In our study, PAs were tested with protocorms obtained after 120 days of in vitro germination, while in the experiments performed with microalgae and PAs, the protocorms were 90 days old.…”

Cattleya warneri, an orchid with high ornamental potential, suffers indiscriminate harvest and is classified as a vulnerable species, requiring propagation studies. The aim of this study was to evaluate the effect of biomass or aqueous extract of Desmodesmus subspicatus microalga, polyamines (PAs) and plant growth regulators (PGRs): 6-benzyladenine (BA) and α-naphthaleneacetic acid (NAA) on the in vitro propagation of C. warneri using the thin cell layer (TCL) technique. Entire protocorms and transversal sections (tTCLs) or longitudinal sections (lTCLs) were grown in MS culture medium, with the concentration of macronutrients reduced by half (MSM/2) containing D. subspicatus biomass or extract Pas, and BA and/or NAA. The results indicated that the apical tTCLs were the best explants and the entire protocorms formed seedlings. The regeneration of protocorm-like bodies (PLBs) was more efficient with the addition of 1.5 g L− 1 of microalgae biomass (92% and 4.7 PLBs) or 1.0 g L− 1 of extract (100% and 3.3 PLBs) and 8 µM BA (89% and 5.2 PLBs). The biomass (1.0 g L− 1) or extract (2.0 g L− 1) also enabled PLBs regeneration from entire protocorms (70% and 4.0 PLBs, 50% and 3.2 PLBs, respectively). The plant acclimatization was recommended using coconut fiber and vermiculite (1:1, v/v) as substrate (survival rate 84%% and greater fresh mass 0.895 g). In conclusion, a rapid and efficient protocol for the mass propagation of C. warneri was achieved using the TCL technique. In addition, MSM/2 medium supplementation with biomass and extract of D. subspicatus is an effective alternative to replace conventional PGRs.

“…Mahgoub et al (2011) reported that the application of polyamines in cut flower preservative solutions improved flower fresh weight. Abbasi et al (2017) also observed the positive effect of polyamines, such as putrescine, on inhibiting flower aging and prolonging post-harvest life. Mohammadi et al (2014) obtained the highest relative fresh weight from gladiolus flowers treated with 100 mg L −1 putrescine + 100 mg L −1 salicylic acid.…”

“…Means comparison revealed that the application of 150 and 300 ppm of putrescine reduced wilting percentage by 43.45 and 40.11 percent, respectively, but when only 300 ppm of putrescine was applied, no significant differences were entailed versus the control (Figure 7). Abbasi et al (2017) reported the positive effect of polyamines including putrescine on inhibiting flower aging and the extension of post-harvest life. According to the results of ANOVA, vase life was significantly influenced by silver thiosulfate and putrescine at the p < 0.05 and p < 0.01 levels, respectively, but the interactive effect of these factors was not significant for this trait (Table 1).…”

The effect of chemical treatments (silver thiosulfate and putrescine) on vase life and quality of cut Chrysanthemum morifolium (Ram.) flowers

et al. 2020

The effect of silver thiosulfate (STS) and putrescine was studied on the vase life and quality of cut chrysanthemum in a factorial experiment based on a randomized complete block design. The experimental factors were composed of silver thiosulfate at four levels (0 or control, 0.02, 0.05 and 0.1 mM) and putrescine at three levels (0 or control, 150 and 300 ppm). The results showed that the application of STS at the rates of 0.05 and 0.1 mM improved vase life of cut chrysanthemum. Also, putrescine at the 150 and 300 ppm improved vase life by increasing relative weight and decreasing wilting percentage. The interaction of the two studied factors was insignificant for most traits including wilting percentage and vase life, which may imply that the application of either substance alone suffices to improve postharvest quality and it is not necessary to use them simultaneously in the preservative solution.

“…Plants sprayed with foliar putrescine have shown an alleviating mechanism against negative drought effects through well-regulated metabolic routes (Chen et al, 2019), the polyamines are plant growth regulators that can increase cellular division and link to the membranes in order to stabilize and protect them against peroxidation (Abbasi et al, 2017).…”

The purpose of this study was to alleviate the harmful effects of water restriction, by applying foliar doses of putrescine (0, 50, 100 and 150 mg L-1) on basil plants, as well as, understand the different soil water levels (60% and 80% of soil capacity) on plant development. We evaluated the physiology and metabolic pathways of plants. Basil plants under water restriction (60% of soil capacity) reduced their growth and dry matter accumulation, leaf water status, physiological variables, and photosynthetic pigments. Furthermore, the exogenous putrescine sprays, influenced the biometric and physiological variables, photosynthetic pigments, and proline levels. Our research suggests that exogenous putrescine sprays promote different behaviours on Basil spp., through the activation of tolerance mechanisms in basil plants under moderate water deficit, principally by the proline accumulation in the leaves. Moreover, the oil chemical profile was determined by the water availability in the soil.
