摘要:

为筛选出适合郑州栽培的金银花新品种(系),以6个金银花新品种(系)为试材,采用灰色关联法对其农艺性状、光合特性和产量性状分析,并采用DTOPSIS法和主成分分析法对金银花光合特性和农艺性状进行综合评价。结果表明,金银花的11个光合特性和农艺性状均存在差异,变异系数为5.82%~38.01%。单株干重与气孔导度和胞间CO2浓度呈负相关,与其他性状呈正相关,与蕾长、百蕾干重、净光合速率、水分利用率呈显著正相关,金银花各性状对单株干重影响由强到弱为百蕾干重>水分利用率>蒸腾速率>净光合速率>叶长>蕾长>叶宽>叶绿素>胞间CO2浓度>气孔导度。DTOPSIS综合品种(系)排序与单株干重排序一致,主成分分析结果前2名与金银花单株干重前2名排名一致,第5名和第6名排序一致。DOTPSIS和主成分分析法可作为金银花综合评价的方法,‘封花1号’、‘密银花1号’和‘郑银花3号’适合在郑州进行种植。

Abstract:

In order to screen out new varieties (lines) of Lonicera japonica suitable for cultivation in Zhengzhou, six new varieties (lines) of honeysuckle were used as test materials. The grey correlation method was used to analyze their agronomic, photosynthetic, and yield traits, and the DTOPSIS method and principal component analysis method were used to comprehensively evaluate the photosynthetic and agronomic traits of L. japonica. The results showed that there were differences in the 11 photosynthetic and agronomic traits of L. japonica, with a coefficient of variation ranging from 5.82% to 38.01%. The dry weight of a single plant was negatively correlated with stomatal conductance and intercellular CO2 concentration, and positively correlated with other traits. It was significantly positively correlated with bud length, hundred bud dry weight, net photosynthetic rate, and water use efficiency. The influence of various traits of L. japonica on single plant dry weight from strong to weak was as follows: hundred bud dry weight> water use efficiency> transpiration rate> net photosynthetic rate> leaf length> bud length> leaf width> chlorophyll> intercellular CO2 concentration> stomatal conductance. The ranking of DTOPSIS comprehensive varieties (lines) was consistent with the ranking of single plant dry weight. The top 2 in principal component analysis results were consistent with the ranking of the single plant dry weight of honeysuckle, and the ranking of the 5th and 6th was consistent. DOTPSIS and principal component analysis could be used as comprehensive evaluation methods for honeysuckle, and ‘Fenghua 1’, ‘Miyinhua 1’, and ‘Zhengyinhua 3’ were selected as suitable varieties for planting in Zhengzhou.
