A comprehensive comparison on root yield and content of polysaccharides and alkaloids from ten germplasms of Isatis indigotica Fort. in two growing areas

Variations in the morphological and chemical composition of the rhizomes of Polygonatum species based on a common garden experiment

“…A common garden experiment with Isatis indigotica Fort. demonstrated that the polysaccharide content of different provenances was relatively stable, and that of the same provenance in different growing areas was significantly different ( Han et al, 2022 ). This indicates that polysaccharide accumulation as energy storage materials may be strongly related to ecological factors such as the cultivation environment.…”

“…Polygonatum production can be increased through cultivar improvement and efficient cultivation, which will alleviate poverty in underdeveloped mountainous regions ( Si & Zhu, 2020 ). Germplasm resources are the basis for producing high-yielding and high-quality cultivars, as germplasm may include critical alleles for key traits ( Akpertey et al, 2022 , Han et al, 2022 ). Variations in germplasm resources can cause differences in Huangjing's biological, genetic, reproductive, sporulation, and pharmacologic characteristics, as well as chemical composition ( Jiao, 2018 ).…”
