ABSTRACT
Objective:
To study the effects of different inoculation periods on seedling growth and steroidal saponin content of Paris polyphylla var. yunnanensis, in order to lay a foundation for cultivating and domesticating high-quality Paris polyphylla var. yunnanensis.Methods:
The content of steroidal saponins I, II, VI, and VII in the different vaccination periods of Paris polyphylla var. yunnanensis was determined by HPLC. Meanwhile, trypan blue, UV spectrophotometry and so on were adopted to explore colonization rate, colonization intensity, physiological and biochemical indexes, rhizome biomass of the roots of Paris polyphylla var. yunnanensis.Results:
Infection rate of AM fungi was higher in different inoculation periods, activities of protective enzymes, photosynthetic pigments and soluble sugars were increased, soluble protein was not changed, content of MDA was decreased, stress resistance of the seedlings of Paris polyphylla var. yunnanensis was improved, and the growth and development were good. Quality of the cultivar one-year seedlings (recovered in August 2015, T7) was relatively low, and cultivar one-year seedlings (harvested in June or July 2015, T5 and T6) and cultivar two years seedlings (recovered in August 2015, T8) were the best. S2, S3 and S6 treatment groups had better effect in different AM fungi mixed groups.Conclusion:
Seedling growth and steroidal saponin content of Paris polyphylla var. yunnanensis inoculated by different inoculation periods had certain effects.
