“…The vital pigments like chlorophyll, caroteniod content as well as Hill activity were reduced appreciably in sodium arsenate treated seedlings which indicates poor photosynthetic metabolism. The use of GA 3 and kinetin may, to some extent, help to resist arsenic toxicity in the seedling stage, in arsenic contaminated areas (Swarnakar 2017). In our study, the toxic effect of zinc heavy metal decreased gradually with 10, 20 and 30 ppm H.M. applications (IAA + GA 3 + kinetin), and even completely disappeared.…”

In the present study, the effects of 10, 20, 30 ppm hormone mixtures (indole-3-acetic acid + + gibberellic acid + kinetin) with 0.1, 0.3, 0.5 and 1 ppm zinc (Zn) concentrations alone and their mixtures on the cambial activity of sour cherry (Cerasus vulgaris Miller) cuttings were investigated. Morphological and anatomical developments of the plants were observed. The leaves of the plants treated with zinc were found to be greener than the control. Plants treated with zinc faded earlier than the control. The cambial zone thickness, the cambial zone cell line, the radial and tangential lengths of the cambial zone cells decreased with increasing concentrations of zinc and increased with increasing concentrations of hormones. The radial and tangential wall widths of the cambial zone cells increased with increasing zinc concentrations and decreased with increasing hormone concentrations. As a result, in the 0.1, 0.3, 0.5 and 1 ppm Zn concentrations, the cambial zone thickness decreased by 10, 28, 50 and 65%, respectively, compared to the control. Thirty ppm hormone mixture -H.M. (indole-3-acetic acid + gibberellic acid + kinetin) increased the cambial zone thickness by 65, 15, 5% in 0.1, 0.3 and 0.5 Zn, respectively, compared to the control. It was found that plant hormones importantly improved the harmful effects of zinc on the cambial activity of the plant cuttings.

Arsenic toxicity has gained at present an alarming global importance. Pulse crop is very sensitive to arsenic contaminated groundwater. In order to determine the phytotoxicity, effects of Sodium arsenite (NaAsO2) on seed germination and early development of Mung bean (Vigna radiata (L.) Wilczek cv. B-105) seedlings were investigated. Sodium arsenite had a toxic effect and posed a stress over germination parameters and early growth of mungbean seedlings. Considerable reduction in seed germination percentage and seedling vigour index was recorded due to arsenite. Sodium arsenite inhibited growth at very small concentrations such as 0.5μM. With the increase in concentration of sodium arsenite (0.5µM, 1µM, 2µM), significant decrease in seedling length i.e., shoot length and root length was observed. Arsenite was found to be more toxic for root growth than for shoot growth. Decrease in primary leaf area was also observed with increase in concentration of sodium arsenite. Number of stomata decreased and hence, reduction in stomatal density and stomatal index was also observed. Fresh weight and dry weight also reduced appreciably in the arsenite stressed seedlings. Treatment with 2µM concentration proved to be the most sensitive concentration for arsenite application by giving least values for seedling length and seedling vigour index.
