Raw data files associated with the manuscript 'Inferring the effects of sink strength on plant carbon balance from experimental measurements' by Mahmud et al. (2018)

This folder consists of existing dataset from the container volume experiment which was carried out at the Hawkesbury Forest Experiment site (33°37'S 150°44'E) in Richmond, NSW, Australia. The site and experimental setup have been explained in detail by Campany et al. (2017). This dataset is compiled from another data source of Campany C. (2017) which can be found in this link: http://doi.org/10.4225/35/58b4eaa87c64d.<br>In brief, 20 weeks old Eucalyptus tereticornis seedlings in tube stock were chosen from a single local Cumberland plain cohort. Ten additional seedlings of similar age and growth were harvested to measure initial leaf area and dry mass of leaves, stems and roots. A total of 49 Eucalyptus tereticornis seedlings were grown in a range of container sizes (5 L to 35 L) in field conditions, using freely-rooted seedlings as a control for the container size treatments, with the goal to examine how the C balance of the plants are affected to belowground sink limitations. Six container sizes were used with each container experiment had a complete replicate set of six container volumes along with a free seedling. Similar notations are used here as Campany et al. (2017) for the treatments in different pots as 5 L, 10 L, 15 L, 20 L, 25 L and 35 L in respect of their pot sizes. The experiment tracked leaf-level gas exchange, leaf carbohydrate accumulation and seedling allometry over the course of 4 months for all 7 treatments. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.5px Helvetica; color: #023aeb} span.s1 {color: #000000}

本文件夹收纳了源自容器体积实验的现有数据集，该实验于澳大利亚新南威尔士州里士满的霍克斯伯里森林实验站（33°37'S 150°44'E）开展。该实验站点与实验设置的详细说明已由Campany等人（2017年）发表。本数据集源自Campany C.（2017年）的另一组公开数据源，可通过以下链接获取：http://doi.org/10.4225/35/58b4eaa87c64d。
简言之，本研究从本地坎伯兰平原的单一种群中选取了20周生的试管苗细叶桉（Eucalyptus tereticornis）幼苗。另选取10株树龄、长势相近的幼苗进行破坏性收割，以测定其初始叶面积以及叶片、茎秆与根系的干重。共49株细叶桉幼苗被种植于5升至35升不等的一系列容器中，实验于野外条件下开展；以自由生根幼苗作为容器体积处理组的对照，旨在探究植物碳平衡如何受到地下汇限制的影响。实验共设置6种容器体积，每个体积组均配备6组完整重复样本，外加1株自由生根幼苗。本实验沿用Campany等人（2017年）的命名规范，依据花盆体积将不同处理组分别记为5 L、10 L、15 L、20 L、25 L与35 L。实验全程历时4个月，对全部7组处理的叶片气体交换、叶片碳水化合物积累以及幼苗异速生长情况进行了持续监测。
