摘要: 为评价吉林省长白山区辽东楤木的综合品质,选取了吉林省长白山区9份辽东楤木材料,对其生长指标(株高、地径)、顶芽外观品质指标(顶芽基径、顶芽长度、顶芽鲜质量)与营养物质含量(可溶性糖、可溶性蛋白、纤维素、总黄酮、总皂苷与粗多糖含量)进行了测定分析,并采用隶属函数法与主成分分析结合的方法,对9份材料的综合品质进行了评价与排序。结果表明:各材料的生长状况指标与品质指标有明显差异;9份材料的株高与地径间有极显著的正相关性,株高也分别与总皂苷含量和纤维素含量间呈显著相关,顶芽长度、顶芽基径与顶芽鲜质量间也均具有极显著的正相关性,且这3个外观品质指标分别依次与可溶性糖含量、纤维素含量及总黄酮含量间呈较显著的相关性;桦甸材料的综合评价值为0.92,在9份材料中最高,可作为长白山区辽东楤木人工栽培的首选材料,集安、安图、长白、柳河与蛟河材料的综合评价值也相对较高,也可在长白山区辽东楤木人工栽培过程中选用。Abstract: To evaluate the comprehensive quality of Aralia elata from the Changbai Mountain region of Jilin Province, nine Aralia elata materials from the Changbai Mountain region of Jilin Province were selected as the research subjects. The growth indicators (including the plant height and the ground diameter), the appearance quality indicators of the terminal buds (including the basal diameter, the length, and the weight of the terminal buds) and the contents of the nutritional substances (including the contents of soluble sugars, soluble protein, crude fiber, total flavonoids, total saponins, and crude polysaccharide) were measured and analyzed. Moreover, the comprehensive qualities of the nine materials were evaluated and ranked, by integrating the membership function method and the principal component analysis. The results indicated that there were distinct differences in the growth indicators and the quality indicators among these materials. There were highly significant positive correlations between the plant height and the ground diameter, and the plant height was also significantly correlated with the contents of total saponin and crude fiber, respectively. There were also highly significant positive correlations among the length of the apical buds, the base diameter of the apical buds, and the fresh weight of the apical buds of the nine materials. Moreover, these three appearance quality indicators were successively significantly correlated with the contents of soluble sugars, crude fiber, and total flavonoids, respectively. The comprehensive evaluation values of the Huadian material was 0.92, which was the highest among the nine materials, and it can be used as the preferred material for the artificial cultivation of Aralia elata from the Changbai Mountain region. The comprehensive evaluation values of the Ji′an material, the Antu material, the Changbai material, the Liuhe materialand the Jiaohe material were also relatively high, and they can be also used in the artificial cultivation process of Aralia elata from the Changbai Mountain region. The findings of this study can offer a substantial foundation for material selection in the artificial cultivation of Aralia elata in the Changbai Mountain region.
