- 摘要:
- 以长春市牡丹园20个牡丹品种为试材，通过观测物候期和温湿度，分析了物候期与温湿度的关系，以期探讨不同品种的生物学零度及其始花期与空气温湿度的关系，为抗寒品种选育和引种驯化栽培提供依据。结果表明：紫斑牡丹的生物学零度为6.277 ℃，萌动-始花期需要的有效积温为286.8 ℃；中原牡丹的生物学零度为5.417 ℃，萌动-始花期需要的有效积温为311.2 ℃。通过相关分析法得出，牡丹花期与从芽萌动-始花期的空气湿度累计值的相关性不显著，R2=0.015；此期间有效积温累计值与花期相关性显著，R2=0.869；展叶期-始花期有效积温累计值与花期相关性极显著，R2=0.978。
- Abstract:
- An observation of phenological period,temperature and humidity and an analysis of correlation on the phenology and temperature and humidity on the 18 kinds of tree peony to discuss the biological zero of varieties and the relationship of blooming with temperature and humidity which provided a basis for the introduction and domestication and breeding cold cultivation.The results showed that the biological zero of rock′s peony was 6.277 ℃ and effectived accumulated temperature from germination to anthesis was 286.8 ℃.While the tree peony of Zhongyuan Group was 5.417 ℃ and 311.2 ℃.The results showed by correlation analysis. There was not notable level with tree peony′s blooming and atmosphere accumulated from germination to anthesis ,R2=0.015. There was notable level with tree peony′s blooming and effective accumulated temperature from germination to anthesis,R2=0.869,while there was more notable level with tree peony′s blooming and effective accumulated temperature from leaf stage-flowering to anthesis,R2=0.978.
