Effect of Shading and Pinching on Growth and Acanthoside-D content of Acanthopanax divaricatus var. albeofructus and Acanthopanax koreanum Nakai

Abstract

: This study was conducted to identify the effect of shading and pinching on growth and acanthoside-D content of Acanthopanax divaricatus var. albeofructus and A. koreanum Nakai. Different pinching heights showed no significant differences in terms of plant growth and acanthoside-D content but higher values showed that pinching A. divaricatus at 60 ㎝ and A. koreanum at 30 ㎝ favored good growth and higher fresh weight in the shoots. The content of acanthoside-D was not significantly affected by pinching heights. Also, no significant difference in acanthoside-D content was found between the lower and upper part of plant in the first year. However it was much higher in the lower part than the upper part in the second year, which indicated that the content of acanthoside-D was comparatively high in the lower part where lignification is much advanced. Shading showed benefits in terms of growth of A. divaricatus while only 50%-shading was favorable for A. koreanum to achieve superior growth. Overall, results indicated that shading had favorably affected the growth of the 2 Acanthopanax species while no-shading is better if we opt to achieve higher acathoside D content.

“…The cultivation conditions (2007) were 13.1°C average temperature and 1,142 mm average precipitation. The soil conditions were mature soil, pH 7.0, 3.4% soil organic content, 435 ppm available phosphate, and 0.36, 3.0, and 1.2 cmol + /kg of K, Ca, and Mg, respectively [ 16 ]. All samples were cultivated under the same above conditions.…”
