Study on the dynamic growth rhythm of Achyranthes bidentata under different densities / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>The experiment was conducted to study the dynamic growth rhythm of Achyranthes bidentata under different densities.</p><p><b>METHOD</b>The plant samples were collected to measure the growth rate of each organ.</p><p><b>RESULT</b>Under different densities, the growing dynamic rhythm of A. bidentata were similar. The growth of main root exhibited a trend of "slow-fast-slow" by stages. The increase of dry root weight was fastest during the period of 30-40 days before harvest. The dry-matter increasing rate of whole plant was fastest in the later period of branching stage. The differences of root yields among the plants growing under different densities were significant.</p><p><b>CONCLUSION</b>For high yield and good quality, the density of planting of A. bidentata should be considered.</p>
