Abstract
Lycium ruthenicum Murray is a perennial flowering shrub that is widely distributed in salinized arid areas. In the present study, the growth dynamics, chlorophyll content of fresh leaves, contents of the main components in fruit, including polysaccharides, total flavonoids, anthocyanins and proanthocyanidins, the moisture, total ash, and extract contents of three germplasm samples of L. ruthenicum were investigated. The plant height and stem diameter of the three germplasm samples increased with time, but the growth rate was different in each case. Among the materials tested, the Qinghai strains showed the maximum plant height, on August 8th, while the average height was 104.87 cm. The Qinghai strains exhibited the largest stem diameter, on August 31st; the mean value was 3.10 cm. Minqin strains had the highest total chlorophyll and chlorophyll b contents (12.55 mg/g and 4.85mg/g, respectively). Qinghai strains had the highest chlorophyll a contents (8.33 mg/g). The polysaccharide content, anthocyanin content, moisture content, and amount of extract from Qinghai were the highest. L. ruthenicum, introduced from Qinghai, was the dominant strain and had better nutritional properties than the other strains. The results indicate that Qinghai L. ruthenicum is suitable for planting in the Wuwei arid area.
