“…Morita ones (averaged 10.4%). Moraes et al (2013), studied the productivity of stevia in Mississippi, found that dry leaf and steviol glycosides yield of stevia harvested once a year yielded more (6.95 and 0.91 t ha −1 , respectively) than the yield of multiple harvests [two (2.69 and 0.41 t ha −1 , respectively) or three (2.40 and 0.47 t ha −1 , respectively) harvests per growing season]. According the same researchers, the concentration of steviol glycosides was lower (7.51%) when stevia plants were harvested once, as compared with the two (11.91-12.75%) or three (11.16-11.68%) harvests.…”

A 3-year field study was conducted in central Greece to determine the productivity of two stevia [(Stevia rebaudiana (Bertoni) Bertoni] varieties ('Morita' and 'Candystevia') under normal and reduced irrigation (100% and 75% of the evapotranspiration) and fertilization [1:0.8:1.1 or 1:0.4:0.8 N:P:K ratio in the first year and only N fertilization (100% or 74% of the recommended rate) in the second and third years] inputs. Averaged across years, stevia cv. Morita achieved greater dry leaf yield (3.48 t ha −1 ) than the cv. Candy-stevia (2.85 t ha −1 ). Irrigation and fertilization inputs did not significantly affect stevia cv. Morita dry leaf and steviol glycosides (stevioside plus rebaudioside-A) yields; however, decreasing irrigation and fertilization caused slight reduction of cv. Candy-stevia yields. In cv. Morita leaves, the concentrations of stevioside and rebaudioside-A ranged from 5.97% to 7.78% and 3.73% to 4.79%, respectively, while the corresponding concentrations in cv. Candy-stevia leaves were 8.21-9.36% and 3.89-6.33%. Conclusively, both stevia varieties could achieve satisfactory dry leaf biomass and steviol glycosides yield, even when grown under reduced irrigation (at 75% of evapotranspiration) and reduced N fertilization (74% of the recommended rate). Thus, stevia could represent an alternative crop to tobacco in the Mediterranean conditions.

“…The plant is indigenous to tropical and subtropical regions of South America (Lemus-Mondaca et al, 2012). However, there are a few studies subjecting to stevia resistance to cold stress or hardening before the cultivation of this plant in regions with a risk of chilling or frost (Moraes et al, 2013;Soufi et al, 2016). Cold stress is regarded as main limiting factor for stevia cultivation, especially in climates with severe cold winters.…”

Stevia rebaudiana Bertoni is a perennial medicinal herb indigenous to tropical regions of South America. The present study evaluated some physiological changes of the plant under cold in the absence and the presence of polyamine conditions. The results showed photosynthetic pigments and photochemical efficiency of PSII reduced in cold treatment conditions than control, significantly. However, a considerable increase in the parameters was observed in all of polyamine treated goups. Leaf compatible solutes such as proline and glycine betaine that were not shown significantly increasing at cold treatment groups, elevated in the 2 days cold-polyamine-treated group. The similar results were seen for free amino acid and total protein contents of the treated plants. It was also revealed that specific activity of some antioxidant enzymes such as catalase and ascorbate peroxidase increased in cold-treated or cold + polyamine-treated groups than related controls. It caused a significant decrease in H 2 O 2 and malondialdehyde contents of the treated plants. The results indicated an increasing in saturated long chain fatty acids after 4 days of cold at 4 °C. It was concluded that the polyamine supplement can induced a considerable tolerance in stevia plants at cold condition.

“…It is generally admitted that SVgly content gradually increases up to the budding phase and the onset of flowering (Bondarev et al 2003;Ceunen and Geuns 2013). Some studies report the effect of agronomic practices on SVgly accumulation and S. rebaudiana productivity (Andolfi et al 2006;Angelini and Tavarini 2014;Kumar et al 2012Kumar et al , 2013Kumar et al , 2014Lavini et al 2008;Moraes et al 2013;Pal et al 2013;Serfaty et al 2013). However, findings on the effects of plant age on SVgly production are scarce, while S. rebaudiana could be cultivated as a plurennial plant when the climate allows winter survival of the plants.…”

Stevia rebaudiana (Bertoni) Bertoni is a perennial shrub native to Paraguay whose leaves accumulate sweetening compounds of high value: steviol glycosides (SVglys). These diterpenoids differ in the number (1-4) and the nature of sugar units bound to a steviol skeleton: mainly glucose but also rhamnose and xylose. The two main SVglys are stevioside (ST; 3 glucose units) and rebaudioside A (RA, 4 glucose units). Along with an evaluation of genotypic variability for SVglys content and composition, this study investigates the winter survival and the effect of perennial cultivation on S. rebaudiana genotypes through a 2-year experiment conducted on two locations. The first year, a population of 96 genotypes was examined in a nursery field (site A) and a subset of five genotypes was grown in a field trial (site B). The winter surviving genotypes (16 on site A and 5 on site B) were studied the following year, alongside new plantings of the same lines (8 on site A and 5 on site B). The genotypes showed a high variability in SVgly content (from 45.7 to 186.2 mg g -1 DM) and composition along four distinct clusters. There was no correlation between total SVglys content and composition. Genotypes without RA had no other SVglys with more than three conjugated sugars. SVgly content varied among environments and generally increased between 1-and 2-year-old plants, while SVgly composition remained stable. This study showed that breeding for winter survival in temperate conditions would allow an increase in SVgly productivity in a semi-perennial stevia production.
