目的:通过研究不同生长发育期泰半夏干物质及有效化学成分积累规律,以期为半夏的生理与栽培技术提供参考依据。方法:以泰半夏为材料进行盆栽试验,于春秋2个生育周期的各生长时期分别取样测定半夏各器官干物质积累量及块茎总游离有机酸和鸟苷含量。结果:泰半夏在年生长周期内要经历春、秋2个生长高峰,在春季生长过程物质积累量较大,总游离有机酸和鸟苷含量在生长期内呈上升趋势,但在抽薹期与春季倒苗期会有所下降。结论:高温和抽薹会显著影响有机酸的积累,生产上应合理防止热伤害。
OBJECTIVE: To provide reference for the physiology and cultivation of Pinellia ternate by studying the accumulation of dry matter and effective chemical components in different growth and development periods. Methods: The potted experiment was conducted with the material of Pinellia ternata and the dry matter accumulation of each organ of Pinellia ternata and the content of total free organic acids and guanosine in tubers were sampled and sampled at different growth stages of two reproductive cycles. Results: The annual growth of Pinellia ternata to experience two peak growth in spring and autumn, the accumulation of material in the spring growth process larger, total free organic acids and guanosine content increased during the growth stage, but in the bolting stage With the fall of the spring seedlings will decline. Conclusion: High temperature and bolting will significantly affect the accumulation of organic acids, should be reasonable to prevent heat injury in production.
