TLDR
In this paper, the authors used perlite with a nutrient solution and 0, 1, 2.5 and 5 ppm levels of Na2CrO4 and showed a significant decrease of top growth and chlorosis in trifoliated leaves.Abstract:
Bush beans (Phaseolus vulgaris L. cv Contender) were grown on perlite with nutrient solution and 0, 1, 2.5 and 5 ppm levels of Na2CrO4 Significant decrease of top growth and chlorosis in trifoliated leaves were observed for 2.5 and 5 ppm Cr, with Cr concentrations (μg/g) in tops:≥ 12.1, in roots:≥ 509.9. Cr decreased K, Na, Mg and Fe concentrations, and increased P and Mn concentrations in roots. In tops decreased N, K, Na and Fe concentrations and increased Mn and Ca concentrations were observed, Translocation of P, Zn, Cu and Fe was inhibited; Ca and Mn translocation was generally enhanced. P/Fe ratio was increased up to 60% in chlorotic plants, indicating a shift from Fe2+ to Fe3+.read more

Chromium as an Environmental Pollutant: Insights on Induced Plant Toxicity
TL;DR: Symptoms of Cr toxicity in plants are diverse and include decrease of seed germination, reduction of growth, decrease of yield, inhibition of enzymatic activities, impairment of photosynthesis, nutrient and oxidative imbalances, and mutagenesis.

Chromium (VI) accumulation reduces chlorophyll biosynthesis, nitrate reductase activity and protein content in Nymphaea alba L.
TL;DR: It could be inferred that chromium toxicity is not located at the level of ALA synthesis, but, probably at the ALAD activity which was more severely affected during chlorophyll biosynthesis, which resulted in reduced totalchlorophyll content.

Chromium Accumulation and Toxicity in Aquatic Vascular Plants

TL;DR: Chromium poisoning among leather tanners has long been known and the workers have been found to suffer from ulcers, allergic dermatitis, lung cancer, and liver necrosis due to prolonged contact with chromium salts.

Interaction of bioaccumulation of heavy metal chromium with water relation, mineral nutrition and photosynthesis in developed leaves of Lolium perenne L.
TL;DR: The chromium stress decreased CO2 assimilation rates mainly due to stomatal closure, which reduced water loss by transpiration without decreasing the cellular available CO2, and non-radiative energy dissipation mechanisms were triggered during stress.

Chromium uptake and transport in barley seedlings (Hordeum vulgare L.).
TL;DR: Inhibitor studies indicate that CrO42- uptake is “active” whereas Cr3+ uptake is passive, demonstrating that the two forms do not share a common uptake mechanism, and provides a physiological basis for previous observations.
