“…The decrease in Chl a and Chl b induced by Cd treatments was as follow: 27% and 52% at 25µM and 28% and 56% at 50µM Cd, respectively. The decrease in leaf Chl content with increasing Cd-concentration was in accordance with the results of Drazic and Mihailovic (2005). Cadmium may have inhibited the production of Chl by affecting both the synthesis of 5-aminolevulinic acid and the protochlorophyllide reductase (Stobart et al 1985).…”

“…These results are in accordance with some of the results of Ouariti et al (1997) and Lagriffoul et al (1998) who used other plant tissues.

The effect of foliar application of kinetin on the growth and some physiological processes of pea plants growing in soil supplemented with 25 or 50µM Cd were studied. Cadmium treatment inhibited the growth rate, chlorophyll (Chl) content, net photosynthesis (P N ), content of soluble sugars and free amino acids of either shoots or roots. The application of kinetin (kin) enhanced the growth rate, Chl content, P N , soluble sugars and free amino acids content of shoots and roots; dark respiration rate (R D ), contents of soluble protein and proline were increased by cadmium treatment. The addition of kinetin to Cd-stressed plant reduced R D , soluble protein and proline content. Considerable variations in the content of Na + , K + , Ca 2+ and Mg 2+ were induced by Cd-treatments. Foliar application of kinetin exhibited a favorable effect on the accumulation of some ions and antagonized or ameliorated the inhibitory effect of Cd stress on some others.

In this study, the phytotoxicity of disinfectants prepared on the base of sodium hypochlorite was determined. For our tests two commercial products, Savo and Dom Amor, as well as 10% NaClO solution were used. While Savo contained only NaClO, Dom Amor contained NaClO and earthworm enzymes. Products on the base of NaClO are used in households for cleaning and disinfection of floors, furniture, sanitary and kitchen equipment. Savo may be used for the disinfection of drinking waters as well. Products with NaClO are also used for bacteria, algae and pathogens reduction in irrigation waters. As a subject, young seedlings of mustard Sinapis alba L. were used for the study of chronic toxicity. The observed parameters of the inhibition of roots and shoots growth, dry (DM) and fresh (FM) mass as well as photosynthetic pigments production (chlorophyll a, b, carotenoids) and water content in the plants were determined. The results point out that Dom Amor was the most toxic for S. alba seedlings growth and the rank order of the FAC contents for both plant parts was arranged as: Dom Amor > Savo > NaClO. All disinfectants reduced the DM and FM of roots; however, they stimulated biomass production in the shoots. On the basis of the obtained results it could be concluded, that disinfectants stimulated photosynthetic pigments production and reduced water content mainly in the roots. Dom Amor did not significantly reduced the water content in the shoots and for this parameter the following rank orders of inhibition for roots and shoots could be arranged as NaClO > Dom Amor > Savo and NaClO > Savo > Dom Amor, respectively. All commercial products increased chlorophyll a (Chla) and the carotenoids (Car) content in the shoots. As significant increase was confirmed first for Chla whose content in the presence of NaClO at concentration 24 mL/L overextended that in the control by 3.5 times. The rank orders of stimulation for Chla and Car were NaClO > Savo > Dom Amor and Dom Amor > NaClO > Savo, respectively.

“…The plant material was then oven-dried (55°C) to constant weight. The water content of the plants was determined on the basis of the fresh and dry mass as follows (Drazic and Mihailovic 2005): WC = (FM -DM)/DM (g g -1 DM) where WC = water content, FM = fresh mass, DM = dry mass.…”

Phytotoxicity of Se(IV), Se(VI), Cu and Zn to Sinapis alba L. seedlings was expressed by inhibition of selected physiological processes (root and shoot growth, fresh and dry biomass production, water content) and correlated with their bioaccumulation. Roots growth was inhibited more than that of shoots and only Se(IV) reduced also shoots growth (IC 50 = 25.8 mg L -1 ). Se(VI) decreased more roots (IC 50 = 23.6 mg L -1 ) than shoots growth (IC 50 = 461.4 mg L -1 ). Phytotoxicity to roots growth increased as follows: Zn < Se(VI) ≅ Cu < Se(IV). All metals, except Cu, decreased more roots and shoots fresh mass than that of dry mass. Water content was for all (semi)metals more depressed in shoots, however, for Zn any significant changes in roots WC were confirmed. In any case transportation index Ti overreached value 1 and that indicate metals storage in the roots; however, for control the opposite results were obtained. While the highest bioaccumulation factor (BAF) was determined for Cu in both roots (1.016) and shoots (0.271) the lowest values for this parameter were confirmed for Se(VI) in the roots (0.061) and for Se(IV) in the shoots (0.010). While in the control Cu, Se and Zn content was higher in the shoots, treatment with these metals increased their accumulation mainly in the roots. Statistically negative correlation was confirmed among Se(IV), Se(VI) and Cu accumulation in the roots and water content in the roots, and among Se(IV) and Cu accumulation in the roots and water content in the shoots.
