摘要:

为探究不同天竺葵种质生长习性和农艺性状的表现及差异性,选用28份天竺葵种质资源为试验材料,观察和测定其农艺性状指标,采用单因素分析、相关分析、差异性分析、聚类分析等方法进行综合分析。结果表明,A06的株高最高,达到13.87 cm。茎粗最大的为C03(12.86 mm),最小的为A01(8.06 mm)。A07的分枝数和A06的叶片宽表现最好,分别达到了4.00枝和12.80 cm。A02的相对叶绿素含量(SPAD值)最大,达到48.43。28份天竺葵种质资源的花朵数为4.33~13.33朵,其中B系列整体花朵数较多,高于其他系列。A06的花梗长最长,达到20.00 cm,B01最短,为9.53 cm。9个农艺性状的平均变异系数为15.94%,其中,花朵数变异系数最大,为33.98%。株高与冠幅、花梗长,茎粗与冠幅、叶片宽,冠幅与分枝数、叶片宽、花梗长均存在极显著(p<0.01)正相关关系。株高与茎粗,花梗长与茎粗、叶片宽均存在显著(p<0.05)正相关关系。SPAD值与冠幅、叶片宽存在极显著负相关关系。此外,基于9个农艺性状对28份天竺葵种质资源进行聚类分析发现,当距离系数为15时,可以将28份天竺葵种质划分为6类。其中,第Ⅱ类的茎粗、冠幅、叶片宽、花梗长最大;第Ⅲ类在株高和分枝数表现最好;第Ⅴ类的叶片数最多,叶用价值较高;第Ⅵ类的SPAD值和花朵数最大,表明其生殖生长旺盛,光合作用效率更高。本研究为天竺葵品种选育及栽培管理提供理论参考。

Abstract:

To investigate the performance and variability in growth habits and agronomic traits among different Pelargonium hortorum germplasms,28 Pelargonium hortorum germplasm resources were selected as experimental materials. Agronomic traits were observed and measured,followed by comprehensive analysis using one-way ANOVA analysis,correlation analysis,variability analysis,and clustering analysis.The results showed that A06 had the highest plant height,reaching 13.87 cm,while the maximum stem thickness was 12.86 mm(C03)and the minimum was 8.06 mm(A01). A07 demonstrated the highest branch number(4.00 branches),A06 showed the greatest leaf width(12.80 cm),and A02 recorded the highest relative chlorophyll content(SPAD value),reaching 48.43. Flower number in 28 Pelargonium hortorum germplasm resources ranged from 4.33 to 13.33,with B series varieties displaying higher flower numbers than other series. A06 had the longest pedicel(20.00 cm),while the shortest was B01(9.53 cm). The average coefficient of variation(CV)for the nine agronomic traits was 15.94%,with the flower number exhibiting the highest coefficient of variation at 33.98%. Further analysis revealed that plant height showed a highly significant(p<0.01)positive correlation with crown width and pedicel length,and stem thickness exhibited a highly significant positive correlation with crown width and leaf width. Crown width demonstrated a highly significant positive correlation with branch number,leaf width,and pedicel length. Plant height showed significant(p<0.05)positive correlation with stem thickness,pedicel length showed significant positive correlation with stem thickness and leaf width. Notably,SPAD value displayed a highly significant negative correlation with crown width and leaf width. Furthermore,hierarchical cluster analysis based on nine agronomic traits categorized 28 Pelargonium hortorum accessions into six distinct groups at a distance coefficient of 15. Group Ⅱ exhibited the largest stem thickness,crown width,leaf width,and pedicel length,while Group Ⅲ performed best in plant height and branch number. Group Ⅴ had the highest leaf number and superior leaf utility,whereas Group Ⅵ demonstrated the highest SPAD value and flower number,indicating vigorous reproductive growth and higher photosynthetic efficiency. This study provides theoretical reference for the breeding and cultivation management of Pelargonium hortorum.
