Six methods of drying after fresh harvest were evaluated for end product quality and saponin content of Panax notoginseng, comparing the effects on drying time, drying rate, density, appearance, and internal components of roots. [Article in Chinese] Liu 2019

 

This paper investigates the qualitative characteristics of commercial Panax notoginseng products based upon four commodity specifications (i.e. root, including Cunqi and Dongqi, rhizome, and rootlet) and harvest time. [Article in Chinese] Liu 2016

 

Various spectra of photosynthetic light were assessed for effects on growth, photosynthesis, and active components of Panax notoginseng. [Article in Chinese] Luo 2014

 

Using field survey sampling at harvest, agronomic traits of traditional and new cultivated fields of Panax notoginseng leaf, stem, and root were measured and observed; longitude and latitude, elevation, soil type, and land form of producing area were compared. [Article in Chinese] Zheng 2014

 

Accumulation of saponins in Panax notoginseng seedling exhibited a time-dependent increase after germination, with Rb1, Rg1, Re, Rd, and R1 appearing successively in seedling root. Wang 2011

 

In a study of 92 samples of 3-year-old Panax notoginseng plants from 4 counties in Yunnan province, China, domesticated ginseng was found to maintain a fair level of biodiversity with. no genetic drift in populations Wang 2008

 

Three methods of adventitious root induction from callus culture of Panax notoginsen were evaluated using hormone elicitation and the effects of four modes of separating adventitious roots from parent tissues on culture compared. [Article in Chinese] Gao 2006

 

Ginsenoside production in Panax notoginseng suspension culture was shown to increase with a single elicitation with methyl jasmonic acid and to increase again with repeated elicitation. Wang 2005

 

Effects of calcium on biosynthesis of ginsenoside Rb1 and several calcium signal sensors were evaluated in suspension cultures of Panax notoginseng cells; intracellular ginsenoside Rb1 was found to be dependent on Ca2+ concentration, possibly via signal transduction pathway of CaM, CDPK, and UGRdGT. Yue 2005

 

A survey method for Panax notogingseng cultivation based on remote sensing was developed, including data-source selecting, image processing, interpretation, and validation. [Article in Chinese] Zhou 2005

 

Leaf size, especially width, was determined to be the highest physiological trait associated with root size among 5 other variables in 52 samples of Chinese Panax notoginseng; height of plant and diameter of stem also should be considered. [Article in Chinese] Chen 2004

 

Using Notoginsenoside R1, ginsenoside R(g1), R(b1), R(d), dencichine, flavonoid, and polysaccharides as markers, the best quality of Chinese Radix Notoginseng was found in southwestern Wenshan and the best season for harvest found to be September to October. Dong 2003

 

The optimal harvest time of Panax notoginseng for highest saponin content was found to be from October through December, with total saponin contents decreasing from April through July and increasing from August through December. [Article in Chinese) Cui 2001

 

Calli induced from Panax notoginseng roots, tubers, stems, petioles, leaves, and flower buds were found to synthesize saponins, including ginsenosides Rb1, Rg1, and Rh1; callus saponin content was higher than intact plants, callus also produced a larger amount of sapogenins than intact plants. Zheng 1989
