The effect of high CO(2) (1% CO(2)/21% O(2)) on the activity of specific forms of catalase (CAT-1, -2, and -3) (EA Havir, NA McHale [1987] Plant Physiol 84: 450-455) in seedling leaves of tobacco (Nicotiana sylvestris, Nicotlana tabacum) was examined. In high CO(2), total catalase activity decreased by 50% in the first 2 days, followed by a more gradual decline in the next 4 days. The loss of t...

In the present study, the aqueous extract of Vigna unguiculata (L) Walp seed was evaluated for its hepatoprotective effect on etahnol induced acute liver damage on Wistar albino rats. The degree of protection was measured by using biochemical parameters such as serum glutamate oxalate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP), total bilirubin ...

Low soil temperature is one of the reasons for poor germination and establishment of maize. The aim of this study was to evaluatethe possibilityof improvingthe seedling emergence and performance of maize under low temperature stress. A pot experiment was conducted on Zea maize (single cross 704) at 14 ºC as cold stress and seed treatments were priming with  200,  300 and 400ppm of GA3; 100, 200...

Poor germination and low seedling growth of stevia are common problems in the cultivation of the plant. Nutri-priming is a newest, safe, easy, and effective method to increase germination characteristics and seedling tolerance against stress. The objective in this study was to assess the effect of nutri-priming with nano potassium (nano-K), paclobutrazol (PBZ), and salicylic acid (SA) on stevia...

In order to investigate the effect of seed inoculation with Plant Growth Promoting Rhizobactria (PGPR) on germination and some biochemical and physiological indices of Cumin (Cuminum cyminum L.) under salinity stress, an experiment was conducted. Experimental factors were included in seed priming in five levels (seed inoculation with three strains of Pf2, Pf25 and CHA0 of Pseudomonas fluorescen...
