Variation of photosynthesis, secondary metabolites and antioxidant activities in third generation of spaceflight-induced Salvia miltiorrhiza.

ABSTRACT:

Objective

Spaceflight has long been perceived as an effective way to improve the quantity and quality of plants with wide applications. In order to obtain stable and inheritable descendants of spaceflight-induced Salvia miltiorrhiza lines, we investigated and analyzed four lines m16, m50, m51, m57 (three individuals of each line) and the ground control (three individuals) of the third generation of spaceflight-induced S. miltiorrhiza from primary/secondary metabolism and antioxidative abilities.

Methods

A portable photosynthesis system (Li-6400) with red/blue LED light source was used to perform the photosynthetic characteristics to evaluate their primary productivity. The secondary metabolites (phenolic acids, tanshinones, total phenolics and flavonoids) and a
