不同产地枸杞质量的比较研究

以‘蒙杞1号’、‘柴杞’、‘宁杞1号’为试验材料,测定了枸杞果实百粒质量、果实纵、横径,坏果率、色泽、籽实比及主要成分.结果表明:不同枸杞品种及不同产地同一品种枸杞品质存在不同程度的差异;品种和气候条件共同影响枸杞品质,低温、高海拔、长日照有益于枸杞质量;永登县上川镇产枸杞百粒质量15.35g、果实纵径16.56mm、横径6.39mm、坏果率3.0%、色泽为B级、多糖含量3.4%、浸出物79.87%、总灰分4.52%、酸不溶性灰分0.2%,质量处中等水平,说明该区有益于枸杞种植;宁夏地区是枸杞的优势产区.

Comparison on quality of Lycium barbarum from different production areas

To evaluate the quality of L.barbarum from different production areas of Gansu,Qinghai and Ningxia,the fruit quality of major cultivars,'Monqi 1','Ningqi 1' and 'Chaiqi 1' was analyzed.The results showed that there was a different quality among different cultivar and the same cultivar in different production areas.The ecological factors,such as higher altitude,lower temperature and longer sunshine contributed a better quality of fruit.For fruit from Shangchuan of Yongdeng County,the quality was medium level,with 15.35 g of 100-seed weight,16.56 and 6.39mm of longitudinal and equatorial diameter,3.0% of bad fruit rate,B grade in color,3.4% of polysaccharide,79.87% of extraction,4.52% of total ash and 0.2% of acid-insoluble ash.It is suggested that Shangchuan of Yongdeng County in Gansu is a suitable area for L.barbarum growth;however,Ninxia is superiority area for L.barbarum growth.
