研究了植物生长调节剂氯吡脲(CPPU)的1×10-6,0.67×10-6,0.5×10-6清水稀释液对五味子Schisandra chinensis的果实形态和有效成分木脂素的影响。结果表明,CPPU叶面微肥促进了五味子果穗横径生长,抑制了果穗纵径生长。同时,3种不同浓度CPPU清水稀释液对五味子千粒重,产量均有不同程度的提高,其中0.5×10-6CPPU千粒重,产量最大,1×10-6次之,0.67×10-6提高的最少。通过测定不同采收期CPPU处理的五味子6种木脂素含量表明,木脂素含量的主要积累期在幼果期到半成熟果期,0.67×10-6的氯吡脲清水稀释液有利于五味子醇乙、五味子丙素、五味子乙素的积累。在五味子临床需求较大的今天,对CPPU胁迫对五味子的研究应予以高度重视。
The effects of 1 × 10-6, 0.67 × 10-6 and 0.5 × 10-6 water dilutions of the plant growth regulator, clopidogrel (CPPU), on fruit morphology and the active ingredient lignans of Schisandra chinensis were studied. The results showed that the foliar fertilizer of CPPU promoted the growth of the diameter of Schisandra sphenanthera fruit and restrained the longitudinal growth of the ear. At the same time, three different concentrations of CPPU water dilution of Schisandra one thousand grain weight, yield increased in varying degrees, of which 0.5 × 10-6CPPU 1000-grain weight, the largest output, 1 × 10-6 times, 0.67 × 10-6 increased at least. The determination of 6 kinds of lignans in Schisandra chinensis by different CPPU treatments showed that the main accumulation period of lignan was from young fruit to semi-mature fruit, and 0.67 × 10-6 was the best Schisandra B, Schisandra C, Schisandrin B accumulation. Schisandra clinical needs in the larger today, CPPU stress on the Schisandra research should be highly valued.
