摘要:
【目的】东京野茉莉是一种优良的材油两用树种,研究其不同家系苗期生长的差异,为发掘、选育优良种质资源提供参考。【方法】对江西省吉水县40个家系东京野茉莉1、2年生幼苗株高、地径、干质量等进行测定并分析。【结果】1年生幼苗株高为66.71~90.02 cm,平均值为81.52 cm,地径为11.27~18.13 mm,平均值为16.06 mm,整株干质量为27.07~146.41 g,平均值为80.79 g; 2年生幼苗株高为120.07~175.64 cm,平均值为156.52 cm,地径为17.19~25.28 mm,平均值为21.31 mm,整株干质量为112.20~415.99 g,平均值为274.90 g。通过相关性分析得出,1年生与2年生幼苗的生长具有显著的相关性。通过主成分分析将40个家系种质分为三大类。【结论】结合株高、地径、生物量等生长指标及主成分分析,1年生东京野茉莉幼苗株高、地径、干质量分别在76.78 cm、15.84 mm、76.16 g以上,2年生幼苗株高、地径、干质量分别在153.72 cm、20.79 mm、246.19 g以上,可筛选出8个(15、16、22、23、31、32、33、37号家系)苗期生长性状优良的东京野茉莉家系。
Abstract:
【Objective】 Styrax tonkinensis is a species with functional uses as timber and biodiesel. Research on the seedling growth characteristics of different families had an important role for exploring and breeding high-quality germplasm resources. 【Method】 The growth characteristics of one-year-old and two-year-old seedlings, such as the height, basal diameter, and dry weight, of 40 different S. tonkinensis families from Jishui County, Jiangxi Province were studied and analyzed preliminarily. 【Result】 The results showed that the height of one-year-old seedlings ranged from 66.71 to 90.02 cm with an average of 81.52 cm. The basal diameter ranged from 11.27 to 18.13 mm, with an average of 16.06 mm. The dry weight ranged from 27.07 to 146.41 g, with an average of 80.79 g. The height of two-year-old seedling ranged from 120.07 to 175.64 cm, with an average of 156.52 cm. The basal diameter ranged from 17.19 to 25.28 mm, with an average of 21.31 mm. The dry weight ranged from 112.20 to 415.99 g, with an average of 274.90 g. A significant positive correlation between one-year-old and two-year-old seedlings was found through a correlation analysis of growth characteristics. All germplasm resources of S. tonkinensis could be clustered into three groups according to the principal component analysis. 【Conclusion】 Based on the seedling growth characteristics and principal component analysis, eight pedigrees(15, 16, 22, 23, 31, 32, 33 and 37)of S. tonkinensis germplasm were recognized relatively more distinctively. In detail, the height, basal diameter, and dry weight of one-year-old seedlings were more than 76.78 cm, 15.84 mm, and 76.16 g, respectively.The height, basal diameter, and dry weight of two-year-old seedlings were more than 153.72 cm, 20.79 mm, and 246.19 g, respectively.
