Variation of Seed Morphology and Seedling Growth among Different Provenances and Families of Acer tutcheri
[Objective] To detect the characteristics of seed morphology,seed germination and seedling growth,and analyze the correlation with geographic and climatic factors of provenance locations in different provenances of Acer tutcheri.[Method] ANOVA and correlation analysis were used to analyze the seed morphology,seed germination,seedling growth and leaf color value of 18 families of three provenances from natural distribution areas in Guangdong.[Result] The provenance from Zhaoqing (HSD) had the thickest and the widest seeds,the provenance from Shenzhen (QNS) had the thinnest and the narrowest seeds,the provenance from Huizhou (NKS) had the biggest length and 1 000-seed weight.The samara length and width showed extremely significant positive correlation (P ＜ 0.01).1 000-seed weight and germination rate showed significant positive correlation (P ＜ 0.05).Seedling basal diameter of 1-year-old A.tutcheri was proportional to seedling height;the growth of seedling was influenced by geographic and climatic factors of provenance locations.On the aspect of leaf color,the L* value of the families QNS3 and QNS13 was bigger than that of the other families,the b * value of the family QNS13 was bigger than that of the others significantly,and the family NKS14 had the biggest a* value.[Conclusion] The higher the 1 000-seed weight,the higher the germination rate.The basal diameter and height of the seedlings are influenced by geographic and climatic factors of provenance locations.Family NKS14 with better leaf color has the most obvious red color than the others.
