“…According to a study, under the drought stress condition flavonoids largely accumulate in the proximity of ROS generation centers and maintain the plant homeostasis. It was reported that phenolic and flavonoid content was increased in root and shoot during drought condition in Dracocephalum moldavica L. (Halimeh et al, 2013 ) and phenol content was decreased in nigella plant ( Kabiri et al, 2014). In the present research, flavanoid content increased in seedling stage many folds compared to its accumulation in vegetative stage under drought stress suggesting that seedling stage is better equipped to scavenge ROS that are generated during drought conditions.…”

Adverse environmental factors like drought stress result in increased levels of ROS that adversely affect the growth and productivity of plants. The alleviation of oxidative damage and increased resistance to environmental stresses is correlated with an efficient antioxidant system. Antioxidant non enzymatic system as well as enzymatic system neutralize the effects of these reactive oxygen species and help plants to survive in stress conditions. The study was carried out with the aim to understand the effect of drought on antioxidant system in seedling and vegetative stages of drought tolerant as well as sensitive genotypes of Eleusine coracana. Drought was imposed by withholding water for 8 days at seedling and vegetative stages of drought tolerant ie PRM-6107 and sensitive ie PES-400 genotypes of E. coracana. Different enzyme assays and biochemical analysis were performed in leaf samples by following the standard protocols. With the induction of drought, an increment in the level of ascorbate, flavonoid, phenol and proline was recorded in PRM-6107 whereas no significant increase was observed in PES-400. The level of these antioxidants was more in seedling stage than at vegetative stage. Similarly the level of antioxidant enzymes like ascorbate peroxidase, catalase, guaicol peroxidase, superoxide dismutase and glutathione reductase was high in tolerant genotype as compared to sensitive genotype under unstressed condition. Under stress condition, the level of catalase, ascorbate peroxidase and guaicol peroxidase increased at seedling stage while the levels of glutathione reductase and superoxide dismutase increased significantly at vegetative stage of both the genotypes. These results show that PRM-6107 is drought tolerant because the level of antioxidants as well as antioxidative enzymes is high in this genotype in seedling and vegetative stages. Also, the elevated levels of antioxidants and antioxidative enzymes at seedling stage show that plant start combating drought more strongly at seedling stage than at vegetative stage.

“…Generally, our results showed that combination of SA with PEG has improved phenolic compounds production and two key enzymes of phenolic biosynthesis pathway. Kabiri et al (2014) reported that SA increased total phenol, anthocyanin, and flavonoid content under drought stress and drought damages were reduced. In fact SA could induce activity of PAL and TAL activity and consequently phenolic compounds were increased (Bandurska and Cie´slak, 2013).…”

“…The results in our study are in agreement with those reported by other authors. It is known that exogenous SA application enhanced the growth and photosynthetic pigments in several plant species treated under water stress such as wheat (Singh and Usha, 2003), Nigella sativa (Kabiri et al, 2014), Zoysiagrass (Chen et al, 2014), mustard (Nazar et al, 2015). Increase in fresh and dry mass by SA application under drought stress can be related to the positive effect of SA on photosynthetic pigments which led to the improvement in growth.…”

Salicylic acid (SA) is an important plant regulator which is involved in growth, development, and response to stress. This study was aimed to evaluate some physiological and biochemical responses of Artemisia aucheri Boiss. under drought stress after exogenous SA treatment. Experiment was performed in vitro. Polyethylene glycol (PEG/6000) with 0, 2 and 4 % (w/v) was used in MS medium to simulate drought stress and different concentrations of SA (0, 0.01 and 0.1mM) were added. After four weeks, SA alleviated the negative effects of PEG on dry and fresh mass as well as chlorophyll and carotenoid contents. Under drought stress, application of SA decreased storage polysaccharides and increased soluble carbohydrates respectively. Although PEG had no significant effect on flavonoid content, it increased significantly anthocyanin and total phenol content, total antioxidant capacity, PAL (phenylalanine ammonia-lyase) and TAL (tyrosine ammonia-lyase) activity and SA treatment improved these parameters significantly. According to the current data, it was concluded that SA increased drought tolerance of Artemisia aucheri by increasing biosynthesis of phenolic compounds, improvement of TAL and PAL activity as well as also by increased content of soluble carbohydrates.Key words: Artemisia aucheri Boiss., salicylic acid, drought stress; polyethylene glycol, growth, phenylalanine ammonia-lyase, tyrosine ammonia-lyase IZVLEČEK VPLIV SALICILNE KISLINE NA NEKATERE FIZIOLOŠKE ODZIVE VRSTE PELINA (Artemisia aucheri Boiss.) NA SUŠNI STRES V IN VITRO RAZMERAHSalicilna kislina je pomemben rastlinski hormon, ki je vključen v uravnavanje rasti, razvoja in odziva na stres. Cilj raziskave je bil ovrednotiti nekatere fiziološke in biokemične odzive vrste pelina Artemisia aucheri Boiss. v sušnem stresu po zunanjem dodajanju salicilne kisline. Poskus je potekal in vitro, v MS gojišču (Murashige and Skoog., 1962) z dodatkom polietilen glikola (PEG/6000, 0, 2 in 4 % (w/v)) za simulacijo sušnega stresa in dvema različnima koncentracijama salicilne kisline (SA) (0, 0.01 in 0.1 mM). Po štirih tednih je salicilna kislina zmanjšala negativne učinke polietilen glikola na suho in svežo maso kot tudi na vsebnosti klorofila in karotenoidov. V sušnem stresu je uporaba salicilne kisline zmanjšala vsebnost založnih polisaharidov in povečala vsebnost topnih ogljikovih hidratov. Čeprav polietilen glikol ni imel značilnega učinka na vsebnostn flavonoidov je značilno povečal vsebnost antocianinov, celokupnih fenolov, celokupno antioksidacijsko sposobnost, aktivnost PAL (fenilalanin amonium-liaza) in TAL (tirozin amonium-liaza), obravnavanje s salicilno kislino je te parametre značilno izboljšalo. Glede na te rezultate je bilo zaključeno, da salicilna kislina povečuje strpnost na sušo pri vrsti Artemisia aucheri s povečanjem biosinteze fenolnih snovi, z izboljšanjem aktivnosti TAL in PAL kot tudi s povečanjem vsebnosti topnih ogljikovih hidratov.

BACKGROUND Grape berries produce significant amounts of phenolic compounds. These are an essential qualitative factor due to their nutritional value and effect on berry color and texture. Salicylic acid (SA) and its derivatives usually lead to enhancement of phenolic content in plant tissues. The present study was conducted to evaluate the effect of different levels of SA (0.0, 50.0, 100.0, and 200.0 mM) on the production of phenolic compounds and the derivatives (anthocyanin and flavonoid) in the grape berries, with emphasis on malvidin‐3‐O‐β glucoside as a regular anthocyanin in red grapes. RESULT The results showed that total phenolics content were significantly enhanced in SA‐treated (100.0 and 200.0 mM) berries compared to untreated ones. Salicylic acid treatment at all concentrations considerably improved the anthocyanin content in the berries and, compared with untreated berries, the accumulation of malvidin‐3‐O‐β glucoside was higher in SA‐treated fruits. In particular, the 200.0 mM concentration caused approximately two times more malvidin‐3‐O‐β glucoside than the control. The 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) scavenging capacity of the fruits treated with SA were significantly higher than those of the untreated berries. The activity of phenylalanine ammonia‐lyase (PAL) in SA treated fruits significantly increased as compared with the untreated clusters. CONCLUSION A general evaluation of the current results leads us to the conclusion that SA is a suitable and recommendable treatment for improving and increasing the phenolic and antioxidant capacity of grape berries. Spraying grape berries at pre‐véraison stage with SA could therefore be a convenient strategy to increase quality and nutritional value of grape berries considerably. © 2019 Society of Chemical Industry
