Influence on AM fungi infection rate and medicine quality of Pinellia ternata in condition of three soil impact factors / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the influence on AM fungi infection rate and medicine quality of Pinellia ternate in the condition of three soil impact factors.</p><p><b>METHOD</b>Set the orthogonal test of three factors and levels. Determinate the AM fungi infection rate in early stage of mature & stage of mature of P. ternata, and the water content, water soluble extract, butanedioic acid content and alkaloid content of P. ternata tuber that be harvested also had be determinated.</p><p><b>RESULT AND CONCLUSION</b>With the P levels to 30 mg x kg(-1) and 90 mg x kg(-1), AM fungi infection was the best when mixed inoculated of EM. Microbial agent inoculated played a decisive role in P. ternata growth and physiological activity, secondary influenced factor was P concentration, and the water stress was the minimal impact. Mixed inoculated of AM fungi and EM treatment with the low P levels (30, 90 mg x kg(-1)) proved better effect on enhancing the water extract content, anedioic acid and alkaloid content, while decreasing the water contents of P. ternata tuber.</p>
