Influence of insect pollinators and harvesting time on the quality of Stevia rebaudiana (Bert.) Bertoni seeds

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2016
Stevia rebaudiana (Bert.) Bertoni has sporophytic self-incompatibility and this may lead to poor seed yield and quality, which are obstacles to large-scale crop establishment. This research investigated the influence of insect pollinators and the harvesting time on the qualitative and quantitative characteristics of the ripe seeds.

The use of esterase polymorphism for analysis of the genetic diversity and structure of stevia (Stevia rebaudiana Bert. Bertoni) populations

Biochemical Systematics and Ecology, 2011
AbstractNative polyacrylamide gel electrophoresis was used in the current study to identify polymorphisms in α- and β-esterase loci in the leaves of Stevia rebaudiana Bert. Bertoni. The esterases produced from the Est-2 and Est-4 loci were observed as strongly stained bands, and four alleles were detected at each of these loci from the 428 analysed S ...
