Objective:
To study the dynamic accumulation of dry matter and index components and provide reference to the manual cultural technique of Pinellia ternata.
Method:
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.
Result:
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.
Conclusion:
High temperature and bolting affect the accumulation of organic acids significantly, it is reasonable to prevent the temperature stress in production.
