Chemical Mutagen Effect on Physiological Properties of Stevia rebaudiana Bertoni under Salt Stress
Authors
Abstract:
The present study was performed to evaluate the effects of different concentrations of ethyl methane sulfonate (0, 0.1, 0.2 and 0.5%) on some physiological characteristics of regenerated plants from calli of stevia at 30, 60 and 120 min under various levels of salinity stress (0, 50 and 100 mM of NaCl). This experiment was carried out based on completely randomized two-factorial designs with three replications. With respect to the result, the regenerated calli became dark and hidden in the medium under exposure time of 120 min, the length of stem regenerated calli was increased under exposure times of 30 and 60 min. Moreover, our data showed that EMS mutagenesis had a significant effect on physiological traits of regenerated stevia under salinity stress at the probability level of 1%. Consequently, the stevia mutants of M10, M11, and M19 showed the highest resistance to different levels of salinity which can be considered as potential samples for further breeding programs.

Effect of Chemical Mutagen on Some Biochemical Properties of Stevia rebaudiana Bertoni
Induced mutagenesis causes an increase variation of some products with limited genetic resources. In this study, the antioxidant enzymes activity, biochemical properties and glycoside content of Stevia were assessed by EMS (chemical mutagen) based on two experiments as factorial with completely randomized design with three replications. The results of the first experiment showed that some prope...

Sweetleaf (Stevia rebaudiana Bertoni), currently investigated by many researchers, has been known and used for more than a thousand years indigenous tribes of South America, who called it "kaa-hee" ("sweet herb"). Thanks to its chemical composition and processability sweetleaf may be an alternative for synthetic sweeteners. Nutritional and health-promoting aspects of Stevia rebaudiana are prese...

Stevia rebaudiana Bertoni is a small perennial shrub of the Asteraceae (Compositae) family that is native to South America, particularly Brazil and Paraguay, where it is known as "stevia" or "honey leaf" for its powerful sweetness. Several studies have suggested that in addition to their sweetness, steviosides and their related compounds, including rebaudioside A and isosteviol, may offer addit...

Two additional novel minor diterpene glycosides were isolated from the commercial extract of the leaves of Stevia rebaudiana Bertoni. The structures of the new compounds were identified as 13-{β-D-glucopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-oxy} ent-kaur-16-en-19-oic acid {β-D-xylopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)]-O-β-D-glucupyranosyl-ester} (1), and 1...

The experiment was conducted to evaluate the differences of plant growth as well as sweetener material of two types of Stevia rebaudiana under conditions of absence and presence of drought stress. In vitro, the experiment was conducted as drought traits using four levels of polyethylene glycol (0.0, 10,000, 20,000, 30,000 ppm). It was observed that survival % and No. of shoots should be conside...
