Endomycorrhizal fungi inoculation improves development of Stevia (Stevia rebaudiana Bertoni) plantlets during ex vitro acclimatization

Effect of Spacing on Growth, Yield and Chemical Composition of Stevia Plants (Stevia rebaudiana Bert.)

“…For example, in a study on broccoli by Grabowska et al [42], the phosphorus content was greatest in the plants grown with the largest spacing, which was similar to the finding in this study about stevia plants. In the study by Büyük [39], stevia plants had an average phosphorus level similar, though slightly lower (0.27%), to the concentration in stevia plants grown in the spacing of 50 cm × 30 cm. However, the total potassium content in plants analysed by Büyük [39] was almost two times lower than the content of potassium in the stevia plants grown in Poland.…”

The stevia plants analysed by Śniegowska et al [38] had similar potassium concentrations.…”

“…However, plants in the nitrogen fertilization study had a greater average number of leaves on the lowest lateral shoot (29.21) than those grown in different spacings. In the study of Büyük et al [39], stevia plants grown in the spacing of 70 cm × 33 cm in Turkey had an average height of 68.1 cm, which was significantly greater than the height of stevia plants grown in different spacings in Poland. Additionally, the plants in Büyük et al [39] were also characterised by a greater number of shoots, averaging 20.4 per plant.…”

Additionally, the plants in Büyük et al [39] were also characterised by a greater number of shoots, averaging 20.4 per plant. Unlike biometric measurements, different spacings significantly influenced the chemical composition of stevia leaves during two periods: in July, during intensive growth, and in September prior to harvest.…”
