Abstract: 【Objective】 To study the correlation between seed vigor and soil factors of Haloxylon ammodendron in Xinjiang, and to screen the dominant factors affecting its vitality.【Method】 With the seeds of Haloxylon ammodendron in Xinjiang as the test material, the soil factors (pH, organic matter, total nitrogen, total phosphorus, total potassium, available nitrogen, available phosphorus, available potassium) were detected by physical and chemical analysis. Correlation analysis and cluster analysis were applied and principal component analysis and grey correlation analysis were used for comprehensive analysis.【Result】RESULTS: Fresh weight, dry weight, seedling height, germination potential and germination rate of Haloxylon ammodendron were positively correlated with seed vigor index. Comparison of seedling traits and seed vigor in different areas found that the germination potential of Toksun County was The germination rate is better than other seed sources; there are some differences in soil nutrient content and pH in different regions.【Conclusion】1) Comparison of seed traits and seed vigor of different provenance seeds showed that the germination potential and germination rate of Toksun County were better than other seed sources. 2) The correlation between pH value of soil factor, fresh weight, dry weight, germination rate, vigor index I, vigor index II and vigor index III is also an important factor affecting vigor index III

摘要: 【目的】研究新疆梭梭种子活力与土壤因子的相关性,筛选影响其活力的主导因子。【方法】以新疆梭梭种子为材料,通过理化分析检测土壤因子(pH、有机质、全氮、全磷、全钾、速效氮、速效磷、速效钾),应用相关性分析、聚类分析、主成分分析和灰色关联度方法进行综合分析。【结果】梭梭种子鲜重、干重、幼苗高、发芽势和发芽率与种子活力指数均呈显著正相关性,不同地区种子幼苗性状及种子活力的比较发现托克逊县种源发芽势与发芽率优于其他种子来源地;不同地区梭梭土壤养分含量和ph均存在一定差异。【结论】不同种源种子幼苗性状及种子活力的比较发现托克逊县种源发芽势与发芽率优于其他种子来源地。2)土壤因子中的pH对种子鲜重、干重、发芽率、活力指数Ⅰ、活力指数Ⅱ和活力指数Ⅲ的关联度系数相对较高,同时也是影响活力指数Ⅲ重要因素。
