摘要 為明確磴口地區不同產地肉蓯蓉種子質量,采用田間取樣室內測定的方法,測定了磴口地區不同產地肉蓯蓉種子凈度、含水率、粒徑、千粒重及萌發率指標。結果表明:肉蓯蓉大粒種子(>0.7 mm)所占比例、種子千粒重和萌發率指標中以樣品點3最高,分別達到了39.4%、81.7 mg和55.0%,以樣品點5最低,僅為23.6%、61.7 mg和15.5%;肉蓯蓉種子凈度以樣品點2最高(94.1%),樣品點5最低(78.3%)。可見磴口地區不同產地肉蓯蓉種子質量差異明顯,應引起重視。

Abstract To determine the seed quality of C.deserticola in different habitats of Dengkou,field sampling and laboratory measurement method was used to measure the seed purity,moisture content,seed size,1000-grain weight and germination rate index of C.deserticola.The results showed that among the proportion of large seeds(>0.7 mm),1000-grain weight and germination rate index of C.deserticola seeds,the habitat of the sample 3 was the highest,reached 39.4%,81.7 mg and 55.0% respectively,in contrast the habitat of the sample 5 was the lower,only 23.6%,61.7 mg and 15.5%;The seed purity of C.deserticola was the highest in sample station 2(94.1%)and which in sample station 5 was the lowest(78.3%).The seed qualities of C.deserticola in different habitats of Dengkou had obvious differences,which should be paied more attentions.

寄生藥用植物肉蓯蓉(Cistanche deserticola Y.C.Ma)為我國名貴中藥材,具有補精血、滋腎壯陽、潤腸通便之功效[1]。肉蓯蓉主產于我國西北荒漠地區,近年來,隨著市場需求量的不斷增加,野生資源已不能滿足市場需求。為解決藥源供需矛盾,已開展肉蓯蓉的人工種植研究[2-3],目前在磴口地區已大面積進行人工栽培。然而肉蓯蓉人工栽培種植中所用種源混雜,所產藥材質量良莠不齊。通過良種繁育是實現肉蓯蓉優質生產的重要保障,而種源研究是實施良種繁育的研究基礎[4]。目前研究表明,寄主營養[5]、開花期有效積溫[6]、種子發育[7]、種子生長部位[8]、花序長度[9]、授粉方式[10]以及花序打頂處理[11]均會對肉蓯蓉種子質量產生影響。然而不同產地的環境條件也會對種子生長產生影響,但是關于磴口地區不同產地肉蓯蓉種子質量的研究尚未有報道。本研究以磴口地區不同產地肉蓯蓉種子為研究對象,旨在明確磴口地區不同產地肉蓯蓉種子質量性狀,以期為肉蓯蓉種子的良種繁育提供一定的科學依據。……p>
