Abstract

Performance of growth, yield, composition of an introduced Lycium ruthenicum Murr. under different soil conditions in Tianjin.

Abstract

The two-year-old L. ruthenicum seedlings, which introduced from Minqin in Gansu Province to Tianjin under different soil conditions were used as materials to study the differences in growth, yield and composition. The growth period of L. ruthenicum introduced to Tianjin was 8-36 days longer than that of Minqin in Gansu Province. The yield of L. ruthenicum in clay loam was 0.34 kg.m-2, which was higher than that in Minqin area, and the yield in sandy soil was 0.05 kg.m-2, which was lower than that in Minqin area. The anthocyanin contents of L. ruthenicum in clay loam and sandy soil were 14.43 and 13.67 mg.g-1 respectively, which were significantly higher than those in Gansu Minqin. The betaine content in the fruit of clay loam was 2.36%, which was significantly higher than that of L. ruthenicum in sandy soil and Minqin. According to the growth condition and various indexes of L. ruthenicum under different soil conditions, L. ruthenicum showed strong growth adaptability after being introduced into Tianjin, among which it grew better in clay loam.
