Title

Morpho-phytochemical attributes of Echinacea purpurea (L. ) Moench exposed to salicylic acid and citric acid

Pages

  4215-4221

Abstract

 The morpho-phytochemical responses of purple coneflower (Echinacea purpurea (L. ) Moench) to foliar application of salicylic acid (SA) and citric acid (CA) at 0, 1, 5 and 10 mM (at four-leaf stage and two weeks later) were determined in a field experiment. Results indicated that elevated levels of SA and CA induced plant growth and biomass, including plant height, number of branches, leaves, and flowers, fresh and dry weight of aerial parts, and SPAD value. The highest flower number, flower yield/plant, and shoot fresh and dry weights were obtained under 10 mM SA combined with 5 or 10 mM CA treatment. DPPH radical scavenging activity increased about 1. 9 fold under 5 or 10 mM SA combined with 10 mM CA treatments. HPLC analysis revealed that SA and CA enhanced phenolic acids (cynaric acid, chichoric acid, echinacoside, chlorogenic acid, and caftaric acid) production in plants. There was a significant positive correlation between number and yield of flowers on the one hand, and all morpho-phytochemical attributes on the other, except root weight. The data suggested that combination of SA and CA especially at 5 and 10 mM may have higher capacity to improve morpho-physiological traits and phenolic contents of E. purpurea.
