“…Many previous studies discovered that there was a cross-talk between reactive oxygen species and PAs for plant adaptive responses and PA could reduce ROS levels, for example, exogenous PA inhibited the accumulation of O 2 *LSD values where significant differences were detected (P B 0.05) for comparison between Non (non-pretreated) and Pre (exogenous spermidine-pretreated) at a given day Plant Growth Regul and H 2 O 2 in wheat seedlings under osmotic stress (Xu et al 2001;Pottosin et al 2014). Exogenous Spd was able to maintain antioxidant enzyme activities in welsh onion (Allium fistulosum L.) to lessen the oxidative stress by moderating the radical scavenging system (Yiu et al 2009). In current study, our data showed that Spd-pretreated creeping bentgrass showed significantly higher SOD, POD, CAT, and APX activities or exhibited lower decline as compared with untreated plants exposed to drought stress.…”

“…It has been shown that stress-tolerant plants increased endogenous PA levels to a greater extent than sensitive ones (Lee 1997). PA involvement in improving drought tolerance by exogenous application in plants has been reported (Yiu et al 2009). It also has been demonstrated that exogenous spermidine (Spd) was effective in enhancing the activity of peroxidase to lessen in this way the oxidative stress (Roychoudhury et al 2011).…”

Improvement of endogenous polyamine (PA) levels by exogenous spermidine (Spd) application in leaves may promote drought tolerance of plants. In this study, leaves of creeping bentgrass (cv. 'Penn-A4') were pretreated with 0.2 mmol Spd every another day for three cycles before water was limited for 15 days in a growth chamber. The application of exogenous Spd elevated the accumulation of endogenous PA, including putrescine, Spd and spermine in leaves of creeping bentgrass under drought stress. Exogenous Spd effectively alleviated the damage effects from drought stress, as demonstrated by lower O 2 Á-generation rate, H 2 O 2 and malondialdehyde content, higher relative water content, chlorophyll content and antioxidant enzyme activities (superoxide dismutase, peroxidase, catalase, and ascorbate peroxidase) as compared to untreated plants. Additionally, the pretreatment with Spd resulted in a lower accumulation of indole-3-acetic acid (IAA) and gibberellin A 3 (GA 3 ) after 15 days of drought stress, but an unchanged accumulation of abscisic acid compared to the untreated ones. These results suggest that ameliorating drought stress through exogenously applied Spd may be associated with increased antioxidant protection capability and after a longer stress treatment with changed IAA and GA 3 accumulation level on account of improved endogenous PA content. In addition, drought tolerance mechanisms related to PA regulation of phytohormones are very complex and deserve further investigation.

“…According to Dutra et al (2013), the application of spermidine and spermine increased the changes of cellular structure in proembryogenic masses by producing more embryogenic and suspensor cells in Araucaria angustifolia. Exogenous spermidine and spermine also can increase the stress tolerance in Allium fistulosum toward waterlogging, by increasing the free proline accumulation, and help in maintaining high relative water content (Yiu et al, 2009). Spermine and spermidine were synthesized from putrescine by adding an aminopropyl group obtained from decarboxylated S-adenosylmethionine (Duan et al, 2008).…”

Spathoglottis plicata is highly sought after by florists and orchid growers due to its unique structure and colors. However, this orchid is a slow-growing type and thus the planting materials are acutely limited. Therefore, there is a need to improve its multiplication efficiency and speed up its growth in order to meet the market demand. Benzyladenine purine (BAP) has been widely used to improve plantlet multiplication in plant cultures. Polyamines have also been reported to improve the growth and development of in vitro cultures. The objective of this study was to investigate the effects of BAP and different polyamines on the physical and biochemical changes of protocorm-like bodies (PLBs) of S. plicata. Different concentrations of BAP and polyamines (putrescine, spermine, and spermidine) were used. BAP and polyamines were supplemented singly in half-strength MS medium and PLBs were cultured for 2 weeks. It was observed that 5 µM BAP and 25 µM spermidine resulted in the highest fresh weights of 0.38 g and 0.31 g, respectively. The total soluble protein and carbohydrate content for PLBs treated with 25 µM spermidine was 4.85 mg/g FW and 6.36 mg/g FW. A separate experiment was carried out to investigate the interactive effects of 25 µM spermidine with 5 µM BAP. The presence of spermidine in the media reduced the peroxidase and catalase activities by increasing the nitrate reductase activity.

“…A lower concentration (1mM) was slightly effective, and 4mM Cat effects were little different to those of 2mM Cat. Forty eight hours after catechin treatment, the plants were waterlogged for 5 d by placing pots in 65 cm×35 cm×12 cm plastic containers filled with sufficient water to raise levels to 2 cm above the soil surface (Yiu et al 2009). Treatments consisted of control (C), 1, 3, and 5 d of waterlogging, and recovery after 4 d drainage.…”

We studied the extent to which catechin applied as a soil drench modifies the effects of soil waterlogging on plant growth, the functioning of the free radical scavenging system and on oxidative stress levels. Forty-day-old tomato plants (Solanum lycopersicum L.) were treated with 0 and 2 mM catechin 48 h prior to 5 d waterlogging followed by a 4 d drainage period. Exogenous catechin increased total fresh and dry weight of flooded plants, reduced membrane damage, maintained chlorophyll concentrations, promoted photosynthesis and increased ATP concentration in the leaves, and raised sucrose synthase and alcohol dehydrogenase activities in the roots. Catechin pre-treatment also reduced hydrogen peroxide and superoxide radical concentration and increased various components of the antioxidative system in leaves. Catechin treatment affected superoxide dismutase and catalase activities in close coordination with ascorbate peroxidases and glutathione reductase. Exogenous catechin can markedly reduce the waterlogging injury in leaves and roots of tomato by enhancing free radical scavenging system sufficiently to lower hydrogen peroxide and superoxide concentrations
