Data for: Phytomonitoring study on intra urban variations of leaves parameters of some evergreen and deciduous trees

These data explores the hypothesis that the action of stressors changes the state of mineral content at different stages of leaves development in urban environment:
• unfavourable site (US) - high pollution exposure, street and busy roundabout near Timisoara’s urban centre, heavy vehicular load.
• favourable site (FS) - low pollution exposure, the site is not immediately exposed to pollution sources, park.
The method is based on quantifying gravimetric (leaf dry weight - LDW, oganic weight in leaves - LO, ash weight in leaves - LA) and physiological (leaf mineral content - LMC, leaf organic content - LOC, leaf organic content / leaf mineral content ratio - LOC/LMC, leaf mineral deposition in tissues - LTDM) parameters.
Acer platanoides L., Acer pseudoplatanus L., Tilia platyphyllos Scop., Tilia tomentosa Moench., Aesculus hippocastanum L., Aesculus x carnea Hayne, Taxus baccata L., Picea abies (L.) H. Karst, were chosen for this study.

本数据集旨在验证下述假说：在城市环境中，胁迫因子的作用会改变叶片发育不同阶段的矿物质含量状态：
• 不利站点（unfavourable site, US）：地处蒂米什瓦拉市中心附近的街道与繁忙环岛，暴露于高污染环境中，机动车通行负荷繁重。
• 有利站点（favourable site, FS）：为远离污染源的城市公园，受污染程度较低。
本研究采用的定量分析方法涵盖两类参数：重量参数与生理参数。其中重量参数包括叶片干重（leaf dry weight, LDW）、叶片有机质重量（organic weight in leaves, LO）及叶片灰分重量（ash weight in leaves, LA）；生理参数则包括叶片矿物质含量（leaf mineral content, LMC）、叶片有机质含量（leaf organic content, LOC）、叶片有机质与矿物质含量比值（leaf organic content / leaf mineral content ratio, LOC/LMC）以及组织内叶片矿物质沉积量（leaf mineral deposition in tissues, LTDM）。
本研究选取的受试树种包括：挪威槭（Acer platanoides L.）、假挪威槭（Acer pseudoplatanus L.）、欧洲椴（Tilia platyphyllos Scop.）、银椴（Tilia tomentosa Moench.）、欧洲七叶树（Aesculus hippocastanum L.）、红花七叶树（Aesculus x carnea Hayne）、欧洲红豆杉（Taxus baccata L.）以及欧洲云杉（Picea abies (L.) H. Karst）。
