摘要:
为阐明刺槐植物功能性状在黄土高原不同环境下的变异规律，探明刺槐对黄土高原环境的适应策略，对陕西省境内从中部向北的14个县（市、区）的刺槐植物功能性状进行测定与统计分析。研究了不同生境刺槐植物功能性状的种内差异、刺槐功能性状间的相关关系及气象因子对刺槐植物功能性状的影响。结果表明：（1）除叶氮含量（LNC）、根组织密度（RTD）和根氮含量（RNC）在各采样点之间的差异不显著之外，其他8个性状在各采样点之间均表现出显著的差异（P < 0.05）。（2）刺槐植物功能性状相互之间都有一定的相关关系，比叶面积（SLA）与叶厚度（LT）、叶组织密度（LTD）和比根长（SRL）呈极显著负相关关系，根磷含量（RPC）与叶磷含量（LPC）和比根长（SRL）呈显著正相关关系，根组织密度（RTD）与比根长（SRL）呈极显著负相关关系。（3）逐步回归分析结果表明，不同的气象因子对刺槐植物功能性状的影响是不同的，对刺槐植物功能性状影响最大的气象因子是年均降水量（MAP）、年均温度（MAT）和年日照时数（ASR）。
Abstract:
To elucidate the variation in plant functional traits and adaptive strategies of Robinia Pseudoacacia on the Loess Plateau, we measured 10 plant functional traits of Robinia Pseudoacacia in 14 counties along the middle area to the north of Shaanxi province, and analyzed the relationships among these functional traits along environmental gradients. The results showed that leaf nitrogen content (LNC) and root nitrogen content (RNC) have no significant differences among 14 sampling points, while other 8 plant functional traits showed significant differences among sampling points(P < 0.05). Specific leaf area(SLA), leaf thickness(LT), leaf tissue density(LTD) and specific root length(SRL) have significant negative correlations, and root tissue density(RTD) and specific root length(SRL) has the remarkable negative correlation. Different enviromental factors had different impact on plant functional traits. It showed that mean annual precipitation has the greatest impact on plant functional traits of Robinia pseudoacacia, and followed by mean annual temperature and annual sunlight ratio according to the stepwise regression analysis.
