Ecophysiological and seasonal responses of Fabaceae tree species growing in Amazonian degraded area Dataset Jaquetti et al. 2025

The data presented for Photosynthesis, transpiration, stomatal resistance, dark respiration, intrinsic water use efficiency, mid-day leaf water potential, leaf area, nutrients concentrations and nonstructural carbohydrates were collected in the dry and rainy seasons. The experimental design consisted of 12 treatments were a combination of six tree legumes species under fertilization vs. unfertilized plants. The dataset presents individual values for the six studied Fabaceae species Cenostigma tocantinum Ducke, Senna reticulata (Willd.) H.S. Irwin & Barneby, Dipteryx odorata (Aubl.) Willd., Clitoria fairchildiana R.A. Howard., Inga edulis Mart., Acacia spp.. Data was collected in a degraded area of the Balbina Hydropower Dam Forest Restoration Program (1 ̊55’36”S, 59 ̊27’10”W) in Amazonas state, Brazil. The forest restoration experiment evaluated the effects of fertilization and seasonality on ecophysiological characteristics through analysis of variance.本数据集包含的观测指标包括光合作用 (Photosynthesis)、蒸腾作用 (Transpiration)、气孔阻力 (Stomatal Resistance)、暗呼吸 (Dark Respiration)、内在水分利用效率 (Intrinsic Water Use Efficiency)、正午叶水势 (Mid-day Leaf Water Potential)、叶面积、养分浓度 (Nutrients Concentrations) 及非结构性碳水化合物 (Nonstructural Carbohydrates)，相关数据采集于旱季与雨季。本实验共设置12个处理组，为6种乔木豆科物种分别组合施肥与不施肥两种栽培条件。本数据集提供了6种研究豆科 (Fabaceae) 物种的单株实测值，分别为：托坎廷斯苏木（Cenostigma tocantinum Ducke）、网叶决明（Senna reticulata (Willd.) H.S. Irwin & Barneby）、香二翅豆（Dipteryx odorata (Aubl.) Willd.）、费尔柴尔德蝶豆（Clitoria fairchildiana R.A. Howard.）、印加豆（Inga edulis Mart.）以及金合欢属（Acacia spp.）物种。数据采集于巴西亚马逊州巴尔比纳水电站大坝森林恢复项目的退化区域，地理坐标为1°55′36″S，59°27′10″W。本森林恢复实验通过方差分析，评估了施肥措施与季节变化对植物生理生态特征的影响。
