Study ID	ST001713
Study Title	Effects of different planting densities on the metabolism of Panax notoginseng
Study Type	Planting density experiment
Study Summary	At the moderate planting density, the primary metabolism (starch and sucrose metabolism) of the plants were significantly enhanced. However, the strong intraspecific competition at the higher planting densities resulted in stress as well as the accumulation of antioxidants (gentiobiose, oxalic acid, dehydroascorbic acid) and other stress resistance-related metabolites. Interestingly, the planting at low densities with low intraspecific competition disturbed normal carbohydrate metabolism by upregulating galactose metabolism.

Treatment:

Treatment ID:	TR001803
Treatment Summary:	The experimental design for P. notoginseng cultivation is as follows: Each plastic basin (65×40×18 cm) contains about 40 kg natural soil, which was collected from a pine forest in Xundian Country, Yunnan, China (103.29°E, 25.51°N; altitude of 1960 m), then sieved to remove the residue of plant. The soil had the following characteristics: pH 5.17, electrical conductivity 458 μS cm-1, available potassium (K) 6.90 mg kg-1, available phosphate (P) 5.18 mg kg-1, alkali-hydrolyzable nitrogen (N) 172.38 mg kg-1 and organic matter 47830 mg kg-1. 4, 12, 15, 28, 45 healthy one-year old seedlings were planted in January 3, 2016 at a plant spacing of 30 cm, 20 cm, 15 cm, 10 cm and 8 cm, respectively. There were four repeats for each treatment, and a total of 20 plastic basins were placed in a completely randomized block design in greenhouse. The fresh fibrous root of P. notoginseng was collected in November 30, 2016.
