  • 摘要: 黄梅秤锤树(Sinojackia huangmeiensis J. W. Ge & X. H. Yao)是我国120个极小种群野生植物之一。本研究运用独立样本t检验和贝叶斯方差分析比较黄梅秤锤树仅存的1个迁地保护种群和1个野生种群的环境条件、果实形态性状和果实元素含量。结果显示,迁地保护种群和野生种群同处于亚热带地区,年均温和年降水量基本一致。迁地保护种群的果实长度、宽度和长宽比均显著大于野生种群;2个种群在果实重量上呈现相同的趋势,但差异不显著。迁地保护种群在果实形态性状方面,种内变异程度不低于野生种群;土壤和果实中绝大多数元素(Ni元素除外)的含量在2个种群间的变化规律不一致。研究结果表明该物种的迁地保护基本成功,但存在迁地保护种群较小的问题。
    Abstract: Sinojackia huangmeiensis J. W. Ge & X. H. Yao is one of 120 plant species with extremely small populations (PSESP) in China. In this study, independent-sample t test and Bayesian analysis of variance were used to compare the environmental conditions, fruit morphological traits, and fruit element contents of the only remaining ex situ conservation population and one wild population in Huangmei, China. Results showed that the wild and ex situ conservation populations were both located in subtropical areas, with similar mean annual temperature and precipitation. Fruit length, width, and length-width ratio were larger in the ex situ conservation population than in the wild population, whereas fruit mass showed similar trends without significant differences. Intraspecific variations in both fruit length and width of the ex situ conservation population were higher than that fruits of the wild population, and the variations in elements (except Ni) in soil and fruit were inconsistent between the two populations. Our results suggest that the ex situ conservation of S. huangmeiensis is generally successful, but populations are small.
