To study the dynamic accumulation of dry matter and index components and provide reference to the manual cultural technique of Pinellia ternata.
Seedlings of Taizhou P. ternata were used as the pot experiment material, and the contents of free total organic acid and guanosine of each organ were determined at different stages of spring and autumn period.
P. ternata had two growth climax in spring and autumn. Under the same condition of cultivation and management, dry matter largely accumulated in spring. The contents of free total organic acid and guanosine was ascending during the growth period, but dropped during sprout tumble bolting and sprout tumble stage.
High temperature and bolting affect the accumulation of organic acids significantly, it is reasonable to prevent the temperature stress in production.
研究半夏干物质及指标性成分的动态积累规律，为半夏人工栽培技术提供参考。
以泰州半夏幼苗为盆栽试验材料，测定春秋两季不同生长阶段各器官游离总有机酸和鸟苷的含量。
半夏在春秋两季各有一个生长高峰期。在相同栽培管理条件下，干物质主要在春季积累。游离总有机酸和鸟苷含量在生长期间呈上升趋势，但在抽薹期和倒苗阶段有所下降。
高温和抽薹对有机酸积累有显著影响，生产中防止温度胁迫是合理的。
