摘要
目的探讨陇东地区菘蓝干物质和药用成分积累规律,并确定其最佳采收期。方法通过定期调查菘蓝农艺指标和HPLC法测定板蓝根中尿苷、鸟苷、(R,S)-告依春、腺苷含量积累变化规律,应用灰色关联度法评价不同时期板蓝根的综合利用价值。结果株高、株幅、叶长、叶宽、叶片数、叶重、根长、根粗、根重,以及尿苷、鸟苷、(R,S)-告依春、腺苷含量等指标在不同生长时期存在显著变化,并且各指标的峰值不在同一时期;不同品系间上述各指标也存在明显差异。隆德菘蓝和2008-6-2综合利用价值的加权关联度在10月9日最高,2008-11和2016-2在10月24日最高,整体上2008-6-2和2016-2种质优于2008-11和隆德菘蓝。结论建议陇东地区菘蓝最佳采收期为10月中下旬。
AIM To explore the laws in accumulation of dry matter and medicinal ingredients of Isatis indigotica Fort.in Longdong area,and determine the best harvest time to obtain the high-quality and high-yield medicinal plant.METHODS The I.indigotica had its agronomic traits investigated regularly;the accumulation laws of its uridine,guanosine,(R,S)-geichan and adenosine measured by HPLC;and its comprehensive utilization value in different periods evaluated by grey correlation method.RESULTS There existed significant variations among the plant height,plant width,leaf length,leaf width,number of leaves,leaf weight,root length,root diameter,root weight,and the yields of uridine,guanosine,(R,S)-goitrin and adenosine at different growth stages,whose peak values appeared in different period.Additionally,there were also obvious differences in the aforementioned indexes levels among different strains.The highest weighted correlation degree of the comprehensive utilization value of Longde and 2008-6-2 on October 9,and of 2008-11 and 2016-2 on October 24.On the whole,the 2008-6-2 and 2016-2 were superior to 2008-11 and Longde.CONCLUSION It is suggested that the best harvest time of I.indigotica in Longdong area is in mid to late October.
