“…The cultivars 'SW 107', 'SW 129', and 'SW 201', and the line '1090' consistently contained more rebaudioside A than stevioside, while the other plant materials had roughly similar amounts of rebaudioside A and stevioside. These plant compositions are similar to those reported by Xu et al (2013) in China, but differ from the plant composition in many other trials where there was substantially more stevioside than rebaudioside (Behera et al, 2013;Moraes et al, 2013;Pal et al, 2015;Serfaty et al, 2013;Vasilakoglou et al, 2016).…”

“…Averaged over harvest strategies, the cultivars 1049 (7.95 Mg • ha -1 ) and SW 107 (7.41 Mg • ha -1 ) grown at Ontario had the highest leaf yields. Although the stevia leaf yields reported here resulted from relatively brief production seasons, they are similar to those found in many studies (Fronza and Folegatti, 2003;Lavini et al, 2008;Moraes et al, 2013;Prieto et al, 2010;Shock 1982aShock , 1982b, greater than those reported by others (Behera et al, 2013;Serfaty et al, 2013;Vasilakoglou et al, 2016;Xu et al, 2013), but less than those observed by Aladakatti et al (2012) in India over a long growing season with five harvests per year.…”

Stevia (Stevia rebaudiana Bertoni) is a perennial herbaceous plant native to Paraguay, where it was used by the native Guarani peoples for centuries. Although steviol glycosides from stevia are powerful natural noncaloric sweeteners, stevia has been cultivated and commercially available only for the past 50 years. Cultural practices are still in development, and productivity potential in the United States is largely unknown. Currently commercial growers and processors worldwide are seeking to maximize the productivity of rebaudioside A, a steviol glycoside. The trials reported here examined the effects of location, harvest strategy, and cultivar on stevia dry leaf yield, steviol glycoside content, and steviol glycoside yield. Six or seven stevia cultivars were grown for ≈5 months at four western U.S. locations, with an irrigation criterion of 20 kPa. Stevia at every location was subjected to two harvest strategies: either one harvest at the end of the season or two harvests, one midseason and another at the end of the season. The main plots at each location were the stevia cultivars, and the split plots were the harvest strategies in a randomized complete block, split-plot design with four replicates. Dry leaf yield, leaf steviol glycoside content, and leaf steviol glycoside yield varied by cultivar, location, and cultivar by location, but not by harvest strategy or interactions of harvest strategy with location or cultivar. Dry leaf yield averaged 4.12 Mg·ha−1 with significant differences by cultivar and location. One of the steviol glycosides, rebaudioside A yield averaged 300 kg·ha−1 with significant differences by cultivar and by interactions of location with cultivar. Leaf productivity was greater at Ontario, OR, than at Hanford, CA, Indio, CA, or Yuma, AZ. Dry leaf yield greater than 7 Mg·ha−1 and rebaudioside A yields greater than 500 kg·ha−1 were observed at Ontario. Stevia perenniated at Hanford and Indio, providing the option of multiyear harvests from a single planting.

“…Bangi had the highest amount of total (stevioside and rebaudioside A) with 23.79 % while Taman Pertanian contained the lowest amount with merely 5.36 %. The plant compositions with substantially more stevioside than rebaudioside A as observed in this study are similar to other trials reported by Behera et al (2013), Moraes, Donega, Cantrell, Mello, & McChesney (2013), Pal et al (2015), Serfaty et al (2013), and Vasilakoglou, Kalfountzos, Gougoulias, & Reppas (2016). Maximum rebaudioside A: stevioside ratio of 0.33 was observed in MNQ while the minimum ratio of 0.02 was observed in Nilai and Eirete II.…”

Genetic Variabilities of Stevia rebaudiana Bertoni Cultivated in Malaysia as Revealed by Morphological, Chemical and Molecular Characterisations

Stevia rebaudianaBertoni originally from Paraguay belongs in Asteraceae family. It is an alternative source of non-caloric sweetener due to the sweet steviol glycosides contained in the leaves. As an introduced species in Malaysia, it is important to elucidate the genetic variabilities and relatedness among stevia accessions in order to broaden the genetic basis for future stevia breeding. This study described morphological and chemical variations and investigates genetic relationships among stevia accessions derived from across Malaysia and Paraguay using inter simple sequence repeats (ISSR) markers. HPLC (high-performance liquid chromatography) analysis also revealed high variability with stevioside content between 4.54 % (Taman Pertanian) to 20.36 % (Bangi) and rebaudioside A content varied between 0.3 % (Nilai) to 2.04 % (MNQ). From 32 ISSR markers, a total of 332 bands were scored, of which 264 (78 %) were polymorphic. The dendrogram from UPGMA (Unweighted Pair Group Method with Arithmetic Mean) cluster analysis separated 17 stevia accessions into 3 main groups. Rawang and Nilai were found to be closely related. The wide genetic variabilities among stevia accessions are a promising indicator towards the development of new stevia varieties. This valuable information will be able to assist parental selection in future stevia breeding programmes.

“…However, drought induced by the polyethylene glycol in the cultivation of stevia in the study by Hajhishemi and Sofo [34] reduced total chlorophyll content in stevia plants almost two-fold. A study by Vasilakoglou et al [37], on the other hand, has shown that chlorophyll content was almost at the same level in the stevia plants grown with adequate or deficit irrigation.…”

Stevia rebaudiana Bertoni originated in South America, but has gained popularity due to the concentration of sweet steviol glycosides present in its leaves. Stevia is also currently grown on other continents in many countries characterised with warm climate. This research aimed to determine whether different irrigation practices might have a significant influence on the yield and composition of the leaves of stevia plants grown in Poland, in cooler climate than native regions for stevia plants. Stevia plants were grown with four different irrigation regimes: irrigation twice a week, irrigation once a week, irrigation only during times of the drought and not irrigated at all. It was determined that different irrigation regimes have substantial effects on the yield, biometric characteristics and chemical composition of stevia leaves, but none of the irrigation regimes were clearly supreme to the others. Yield of stevia plants that were irrigated once a week or only during the drought times was the highest (2.42–2.58 kg per square meter). Stevia plants that were not irrigated were characterised with the lowest height and lateral width (47.61 and 25.35 cm). Leaves of un-irrigated stevia contained the greatest dry mass content (30.47%) and highest concentration of phenolic compounds (337.88 mg per 100 g of fresh stevia leaves). Stevia plants that were irrigated once or twice a week were characterised with a lower concentration of chlorophylls or carotenoids at the time of the harvest (1.20–1.24 and 2.54–2.58 mg per gram of fresh stevia leaves), but stevia plants that were not irrigated contained a greater amount of chlorophyll and carotenoids (1.58 and 3.17 mg per gram of fresh stevia leaves).
