摘要:

花期物候是观赏牡丹重要的性状,探究不同牡丹品种花期性状生长规律及其与环境因子之间的关系,可为牡丹花期的精准调控和特异种质挖掘及定向育种提供参考。本研究以洛阳市国家牡丹芍药种质资源圃中的29个观赏牡丹品种为试验材料,观察了不同品种的开花习性,测定了其花瓣性状和花期气象因子数据。结果显示,供试牡丹品种的花期在7~13 d,变异系数为17.43%。相关分析表明,花期长度与单枝成花率和花瓣厚度呈极显著(p<0.01)正相关,与光照强度和日最高温度呈极显著负相关,与日平均温度呈显著(p<0.05)负相关,与花色、花型、花瓣数和花径等指标相关性不显著。本研究结果为观赏牡丹品种的资源评价、花期精准调控和特异种质挖掘及定向育种提供了有效参考。

Abstract:

Flowering phenology is a critical characteristic of ornamental peonies. Investigating the growth patterns of flowering characteristics across different peony varieties and their relationships with environmental factors can provide valuable insights for precise flowering period regulation,identification of unique germplasm resources,and targeted breeding programs.This study employed 29 ornamental peony varieties from the Luoyang National Peony Germplasm Resource Garden as experimental materials,investigating their flowering characteristics and measuring data on petal traits and meteorological factors during flowering periods. The results showed that the flowering period of the tested peony varieties ranged from 7 to 13 days,with a coefficient of variation of 17.43%. Correlation analysis indicated that flowering duration exhibited a highly significant (p<0.01) positive correlationwith single-branch flower formation rate and petal thickness;a highly significant negative correlation with light intensity and daily maximum temperature;a significant (p<0.05) negative correlation with daily average temperature;while no significant correlations were observed with indicators such as flower color,flower shape,petal number,or flower diameter. The results of this study provided valuable references for resource evaluation of ornamental peony varieties,precise regulation of flowering periods,identification of unique germplasm resources,and targeted breeding.
