摘要: 为了解翅柃(Eurya alata Kobuski)的萌发特性,以丹江口盐池河镇野生翅柃种子为试验材料,测定不同赤霉素浓度(100、200、400、600 mg/L)和浸种时间(4、8、16、24 h)处理后种子发芽率、发芽势、发芽指数、萌发时滞、萌发历期、平均发芽时间、T50、萌发齐性等指标,采用隶属函数法、主成分分析法、TOPSIS法,结合熵权、变异系数权重法对不同处理进行综合评价。结果表明,赤霉素可促进翅柃种子萌发,赤霉素浓度、浸种时间、不同浓度与时间的交互作用均对翅柃种子萌发产生显著影响。不同评价方法评价结果虽然有所差异,但整体趋势较一致,200 mg/L浸泡16 h在不同评价方法中均排名第1,为翅柃种子萌发的最佳处理组合;该处理下,翅柃种子的发芽率、发芽势、T50均为最优值,发芽指数、萌发时滞、萌发齐性仅次于最优值。综合比较,优选熵权-变异系数组合赋权TOPSIS法为翅柃种子萌发的综合评价方法。指标权重系数分析、指标与综合评价值的灰色关联度分析均表明发芽势、发芽指数、发芽率对翅柃种子萌发的影响最为明显,是评价翅柃种子萌发效果的关键指标。

Abstract: In order to understand the germination characteristics of Eurya alata Kobuski, the seeds of wild Eurya alata Kobuski in Yanchihe Town, Danjiangkou City were used as experimental materials. The germination rate, germination energy, germination index, germination lag, germination duration, mean germination time, days needed to reach 50% of germination rate(T50), germination uniformity(days from 10% to 90% of germination, T10-90) at different gibberellin(GA3) concentrations (100, 200, 400, 600 mg/L) and soaking times (4, 8, 16, 24 h) were measured. The membership function, principal component analysis, TOPSIS method, combined weighting method based on entropy and coefficient of variation were used to comprehensively evaluate different treatments. The results showed that GA3 could promote the germination of Eurya alata seeds. The concentration of GA3, soaking time and the interaction of different concentrations and times had significant effects on the germination of Eurya alata seeds. Although the evaluation results of different evaluation methods were different, the overall trend was relatively consistent. The treatment of 200 mg/L GA3 with 16 h soaking ranked the highest across different evaluation methods, which was the best treatment combination for Eurya alata seed germination. The germination rate, germination energy and T50 under this treatment achieved the highest values, and the germination index, germination lag and germination uniformity were slightly lower than the highest values. Through comprehensive comparison, the entropy weight-coefficient of variation combined weighting TOPSIS method was identified as the preferred comprehensive evaluation method for the seed germination of Eurya alata. The weight coefficient analysis of the indicators, grey correlation analysis between each index and comprehensive evaluation value both indicated that germination energy, germination index and germination rate had the most obvious influence on the germination of Eurya alata seeds, which were the key indicators for evaluating the effect of the Eurya alata seed germination.
