Correlation coefficient (r) between different growth- and physio-biochemical parameters under 20% PEG after 3 days of treatment.

For each parameter, average values of three AtDREB1A transgenic peanut lines along with WT were used. Where: RW-root-weight, SW-shoot-weight, PW- pod-weight, TB- total biomass, HI-harvest index, R:S-root∶shoot ratio, PRO- proline, OP-osmotic potential, RWC- relative water content, EC- electrolytic leakage, CHL-chlorophyll content. *Indicates a significant correlation: *P≤0.05, and **P≤0.01.

针对各参数，本研究采用3个AtDREB1A转基因花生株系及野生型（WT）的平均值进行分析。其中：RW为根重（root-weight）、SW为茎重（shoot-weight）、PW为荚果重（pod-weight）、TB为总生物量（total biomass）、HI为收获指数（harvest index）、R:S为根冠比（root∶shoot ratio）、PRO为脯氨酸（proline）、OP为渗透势（osmotic potential）、RWC为相对含水量（relative water content）、EC为电解质渗漏率（electrolytic leakage）、CHL为叶绿素含量（chlorophyll content）。*表示相关性显著：*P≤0.05，**P≤0.01。本数据集为20%聚乙二醇（PEG）处理3天后，不同生长及生理生化参数间的相关系数（r）。
