“…Wu et al (2004) applied increasing Cd doses (1 and 10 mM Cd) to cotton plants and reported decreasing Zn, Cu and Fe concentrations with increasing Cd doses. Hussain et al (2016) also reported decreasing Zn contents of spinach with increasing Cd treatments. Such decreases were mainly attributed to similar transport and distribution mechanisms of Cd and Zn (Lin & Aarts, 2012).…”

In this study, response of 12 grapevine rootstock genotypes to cadmium (Cd) toxicity were investigated. The Cd application to the soil was made at the beginning of the experiment at 4 different doses. Shoot, leaf and root dry matter yields, leaf Cd, N, P and Zn contents were determined to assess genotype tolerance of Cd toxicity. Present findings revealed that based on shoot, leaf and root dry weights, leaf Cd, N, P and Zn contents, there were Cd-sensitive and resistant genotypes among the present ones. At the greatest Cd dose (Cd20), the greatest Cd contents (µg plant-1) were observed in 8B (6.13), 420A (5.35) and 1103P (4.69) rootstocks and the lowest Cd contents were observed in 99R (1.27) and SO4 (1.58) rootstocks. Among the grapevine rootstocks, SO4 with quite lower leaf Cd accumulation than the other genotypes and increasing shoot and leaf dry weights and leaf N, P and Zn content was identified as resistant against toxic Cd conditions. On the other hand, 8B, 420A, 1103P, 5BB, Harmony genotypes with decreasing shoot, leaf and root dry weights under Cd toxicity conditions, higher leaf Cd accumulations and significantly decreasing leaf N, P and Zn contents were considered as sensitive to Cd toxicity.

“…It is mostly used in fried snacks, locally known as pakora. Spinach has been classified as moderately salt tolerant vegetable crop (Langdale et al, 1971;Hussain et al, 2016). But, germination percentage and germination rate of spinach seed was decreased while mean germination time was increased up to 100 mM NaCl concentration (Keshavarzi et al, 2011).…”

Spinach seeds show low germination percentage and speed due to pericarp imposed physical and chemical hindrance; the problem is further aggravated under saline conditions. To assess seed vigor and repress salinity induced lipid peroxidation, seeds of spinach cultivar 'Desi Palak' were subjected to various treatments viz., soaking in distilled water (for 4 h), washing of seeds with bleach i.e. sodium hypochlorite (for 10 min, 50% of commercial grade), seed priming (30 h) using distilled water i.e. hydropriming (with or without soaking), kinetin (25 ppm, after bleach and soaking; hereafter mentioned as kinetin only for simplicity) or Indole-3-Acetic Acid (IAA 100 ppm, after bleach and soaking; hereafter mentioned as IAA only for simplicity). The effect of seed treatments on seed vigor and salinity tolerance was evaluated through germination test (at 0, 50, 100, 150, and 200 mM NaCl induced salinity) and emergence test (at 0 and 200 mM NaCl induced salinity). Seed priming using IAA showed better final germination and emergence percentage, germination index, germination and emergence energy, seedling biomass, chlorophyll contents and vigor index than control and other seed treatments. All parameters were negatively affected by salinity but were altered to significantly lesser extent in seeds primed with distilled water or IAA, especially IAA at higher (200 mM) salinity levels. Bleach and soaking treatments seemed to soften the pericarp as evident by enhanced germination/emergence, germination energy and index, while reducing mean germination/emergence time. Further seed enhancement and increased biomass production in IAA or hydro-primed seeds (after bleach and soaking) can be attributed to reduced lipid peroxidation as evidenced by low MDA contents in seeds primed with IAA and distilled water, particularly under saline conditions.

Knowing that heavy metals are characterized by the cumulative effects on the one hand and that they are present in biological systems at very low doses, which makes their effects latent and often irreversible. It is in this perspective and in order to try to solve the problem of detoxification of this type of major contaminant, we opted for an effective solution which is detoxification by antagonism based on selective interaction. The choice is made for Cadmium which is considered a very harmful element on the one hand and its almost total presence in the entire ecosystem. The investigation protocol is based on two complementary steps which are: • Determination of the Cadmium toxicity threshold vis-àvis the selected plant Phaseolus-Vulgaris. • Study of the interaction between and Cadmium and Zinc and Cadmium Copper selected for the application And the verification of the reduction of the harmful effect by selective competition.
