Putrescine and Acid Stress : Induction of Arginine Decarboxylase Activity and Putrescine Accumulation by Low pH.
Incubation of peeled oat Avena sativa L. var Victory leaf segments on media of pH 5.0 or below leads to a rapid and massive increase in the titer of putrescine while incubation at pH values above 5.0 causes little or no change. The low pH effect is independent of the buffer system employed. Putrescine levels rise within 3 hours and reach their peak 8 to 9 hours after acidification. At this time...
متن کاملThe Effect of Putrescine and Salicylic Acid on Physiological Characteristics and Antioxidant in Stevia Rebaudiana B. Under Salinity Stress
In order to investigate the effect of putrescin and salicylic acid on some physiological and antioxidant properties of stevia under salinity stress, a factorial experiment was conducted in a completely randomized design with three replications. In this experiment, samples were exposed to different concentrations of putrescine (0, 0.5 and 1 mM), salicylic acid (0 and 0.5 mM) and salinity (0, 75 ...
متن کاملPhysiological response of Okra cv. Kano to foliar application of putrescine and humic acid under water deficit stress
To investigate effects of putrescine (Put) and humic acid (HA) on fruit yield and physiological attributes of okra (Abelmoschus esculentus L. 'Kano') under water deficit stress, a field experiment was conducted in split plot based on a randomized complete block design with three replications. Plants were exposed to three different irrigation regimes (33%, 66% and 100% ETc) and were treated with...
متن کاملPhytochemical and Quality Attributes of Strawberry Fruit under Osmotic Stress of Nutrient Solution and Foliar Application of Putrescine and Salicylic Acid
The moderating role of salicylic acid (SA) and putrescine (PUS) as plant growth regulators (PGRs), on the growth parameters and phytochemical and qualitative characteristics of strawberry fruit 'Selva' under osmotic stress was investigated under soilless culture. The osmotic potential (salinity) of the nutrient solution containing different NaCl concentrations (0, 7.5, 15, 30 and 45 mM) and fol...
متن کاملInteraction Effect of Salicylic Acid and Putrescine on Vase life of Cut Narcissus Flowers
The effects of salicylic acid (SA) and Putrescine (Put), on cut Narcissus was studied. SA (0, 100 and 200 mg l-1) and Put (0, 150 and 300 mg l-1), their combinations were tested as preservative mixture. This study was conducted in a factorial experiment with complete randomized design on 108 Narcissus cut flowers in horticulture laboratory of agriculture faculty of Islamic...
