Abstract:

Anthocyanins are potent free radical scavengers that help plants adapt to extreme environmental stresses and have important nutritional and medicinal value for humans. Studying the effect of habitat conditions on the variation in germplasm in Lycium ruthenicum can provides an important scientific basis for artificial breeding and germplasm innovation. L. ruthenicum collected from various provenances was used as the research object. Analytical methods, including structural equation model (SEM), principal component analysis, and linear regression analysis, were used to explore the effects of space, climate, and soil factors on anthocyanin accumulation in L. ruthenicum fruits. The results showed that: (1) The accumulation of anthocyanin in L. ruthenicum fruits increased significantly as altitude increased (P<0.01); altitude mainly influenced climate (β=−0.99, P<0.001) and soil total phosphorus (β=−0.90, P<0.001). (2) The accumulation of anthocyanin in wild L. ruthenicum fruits was mainly influenced by climatic factors, and the artificial cultivation of L. ruthenicum fruits was mainly influenced by soil total phosphorus. (3) The important climatic factors influencing anthocyanin accumulation in L. ruthenicum were diurnal temperature range (DTR), mean temperature of driest quarter (MTDQ), mean annual precipitation (MAP), and solar radiation. Therefore, environmental factors influencing the anthocyanin accumulation in L. ruthenicum depend on the provenance. Thus, when regulating and improving anthocyanin accumulation, it is necessary to adjust measures to local conditions and develop improvement measures to suit the corresponding environmental driving factors.
