This study was conducted to assess the correlation between growth response, phytoaccumulation factor of different tissues, and elemental composition in tomato seedlings exposed to acid mine water (AMW). In pairwise correlation determinations values of plant height, stem diameter, seed germination indices (radicle length, final germination percentage (FGP), emergency rate index (ERI), vigour index (VI), germination percentage (G%) and germination rate index (GRI)) and the elemental compositions (Cd, Cr, Cu, Ni and Zn) in the different plant tissues, root (root accumulation factor = RAF), stem (stem translocation factor = STF) and leaves (leaf translocation factor = LTF) were selected for the relationship determinations. Pearson correlation coefficients were calculated and revealed the relationships between the paired parameters. The study concluded that the strongly correlated physiological parameters were jointly co-ordinated in tomato seedlings exposed to AMW.
本研究旨在评估暴露于酸性矿井水（AMW）的番茄幼苗的生长反应、不同组织的植物积累因子与元素组成之间的相关性。在成对相关性测定中，选取了不同植物组织（根（根积累因子=RAF）、茎（茎转移因子=STF）和叶（叶转移因子=LTF））中的株高、茎直径、种子发芽指数（胚根长度、最终发芽率（FGP）、出苗率指数（ERI）、活力指数（VI）、发芽率（G%）和发芽速率指数（GRI））以及元素组成（镉、铬、铜、镍和锌）的值进行关系测定。计算了Pearson相关系数，揭示了成对参数之间的关系。该研究得出结论，在暴露于AMW的番茄幼苗中，强相关的生理参数是共同协调的。
