Plant height along the plant diversity gradient in the Jena Experiment (Main Experiment, year 2005)@en

This data set contains measurements of plant height: vegetative height (heighest leaf) and regenerative height (heighest flower) in 2005 from the Main Experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the Main Experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained by bi-annual weeding and mowing. […]本数据集收录了2005年某大型草原生物多样性实验（耶拿实验，Jena Experiment；详细说明见下文）主实验样地的植物高度测量数据，涵盖营养生长高度（最高叶片对应高度）与再生生长高度（最高花部对应高度）。 在该主实验中，研究人员从隶属于4个功能群（禾草类、豆科类、高大草本与小型草本）的60个物种库中，搭建了82块面积为20×20米的草原样地。2002年5月，研究人员从该物种库中选取不同数量的植物物种播种至样地，以此构建植物物种丰富度（1、2、4、8、16及60种）与功能群丰富度（1、2、3、4个功能群）的梯度系列。所有样地通过每年两次除草与刈割进行维护。[…]
