摘要/Abstract

摘要：

该研究以呼伦贝尔羊草(Leymus chinensis)草甸草原割草场为研究对象, 通过对羊草营养生长期内功能性状变化的观测, 研究切根对羊草叶、茎、植株功能性状的影响, 为干扰状态下羊草植株的响应机制和天然割草场植被的恢复提供参考。运用9QP-830型草地破土切根机对草地进行切根处理, 分期测定羊草单株高度、叶长、自然叶宽、展开叶宽、茎粗、茎长、叶质量、茎质量、单株质量等多个功能性状, 通过统计分析切根前后性状的差异, 拟合其变化方程, 探索影响羊草产量的表型性状和质量性状的驱动因子。研究结果显示: (1)切根显著降低了羊草的比叶面积、总叶质量、茎长/茎粗、茎干物质含量, 显著提高了平均叶长和叶面积, 整体上提高了单株质量、株高和植株干物质含量。(2)对照和切根羊草叶、茎功能性状均呈二次曲线变化, 拟合效果达显著或极显著水平。除叶干物质含量、茎干物质含量和茎长/茎粗外, 其余叶、茎功能性状均呈先升高后降低的变化趋势。(3)除叶片数外, 羊草各表型性状之间均呈极显著的正相关关系, 叶质量、茎质量、单株质量之间呈极显著的正相关关系, 比叶面积与质量性状关系不显著。(4)总叶长和总叶质量分别是羊草单株质量表型性状和质量性状之中的最大驱动因子。羊草功能性状间存在协同变化的关系, 切根一定程度上使羊草地上植株的生活史提前。

Abstract:

Aims We investigated root-cutting impacts on functional traits of leaves and stems of Leymus chinensis in the vegetative phase in a meadow in Hulun Buir. The aims are to understand the response mechanism of L. chinensis under the disturbance and to provide a references for the restoration of natural mowing grasslands.

Methods A ground intrusive root-cutting machine (9QP-830) was used to cut roots of L. chinensis in May 2014. Since July 2015, we took plants to measure single plant height, leaf length, natural leaf width, spread leaf width, stem diameter, stem length, leaf mass and stem mass at an interval of 15 days until the end of August. Then statistical analysis was applied for the impacts of the treatment on the traits and driving factors to affect phenotypic and qualitative traits of the plant.

Important findings (1) Root-cutting significantly decreased specific leaf area, total leaf mass, stem length/stem diameter, stem dry matter fraction, and significantly increased average leaf length and leaf area. Therefore, it increased individual plant mass, dry matter fraction and height. (2) Dynamics of the traits for both control and treatment followed a quadratic curve. (3) All the phenotypic traits except for the number of leaves in a plant were significantly positively correlated with each other. Leaf mass, stem mass and individual plant mass were significantly positively correlated with each other, whilst specific leaf area was not significantly correlated with the rest of the quantitative traits. (4) Total leaf length and total leaf mass were the greatest driving factors for aboveground biomass among the phenotypic and quantitative traits, respectively. Root-cutting can advance the life history of plant aboveground to some extent.

Key words: root-cutting, Leymus chinensis, functional traits, vegetative phase, driving factor, life history
