Solute contributions to osmotic adjustment in leaf segments of wheat (Triticum aestivum L.) exposed to polyethylene glycol-induced water deficit.

These source data relate to a manuscript submitted to Plant Environment Interactions of the title above. There were 4 experiments: 0 (preliminary to develop procedures), 1 (rate and time of PEG addition), 2 (additional Na+ and K+), and 3 (additional NO3-). Leaf water content, relative water content, osmotic potential, and osmotic adjustment were measured, along with concentrations of K+, Na+, Cl-, glycinebetaine, proline, total soluble sugars in leaf segments, and of K+, Na+ and Cl- in solution. Full details are provided in the manuscript, whose link will be provided on acceptance. In addition, two previous articles are also linked below. The first in the series is Nio et al. (2011) in Plant Physiology and Biochemistry, which reports previous experiments. The second, Nio et al. (2018) in Agriculture and Natural Resources, reports data from Experiment 1 only. This manuscript reports data from Experiments 2 and 3, and cites the previous articles.

本数据集为提交至《植物环境互作（Plant Environment Interactions）》期刊的上述标题手稿的相关源数据。本研究共设置4组实验：0号为流程开发预实验，1号为聚乙二醇（PEG）添加速率与时间梯度实验，2号为额外添加钠离子（Na+）与钾离子（K+）的实验，3号为额外添加硝酸根离子（NO3-）的实验。本研究测定了叶片含水量、相对含水量、渗透势与渗透调节能力，同时检测了叶片切段中钾离子（K+）、钠离子（Na+）、氯离子（Cl-）、甘氨酸甜菜碱、脯氨酸及总可溶性糖的浓度，以及培养液中钾离子、钠离子与氯离子的浓度。手稿中包含完整的实验细节，稿件录用后将提供相关链接。此外，下方还附带两篇前期相关研究的链接：其一为2011年发表于《植物生理学与生物化学（Plant Physiology and Biochemistry）》的Nio等人（2011）的研究，该文献报道了前期相关实验；其二为2018年发表于《农业与自然资源（Agriculture and Natural Resources）》的Nio等人（2018）的研究，仅包含1号实验的数据。本手稿涵盖2号与3号实验的数据，并引用了上述前期文献。
