Heavy metals are widely available in the environment due to the natural processes, industrial, anthropogenic activities and ultimately in the results contaminate the immediate environment. The presence of the heavy metals such as Pb, Cd, Cr, Ni, Fe and Cu in environment disturb the quality of ecosystems, soils, water, air and vegetation. The chromium metal at higher level in ecosystem is an alarming signal for both developed and developing countries. Pennisetum glaucum is an annual grass which is widely cultivated in drought, rain fed and high temperature areas. The limited amount of literature available on the impact of chromium stress on P. glaucum. This study was conducted to investigate the beneficial or harmful effect of chromium stress on seed germination and seedling growth performances of P. glaucum in in vitro conditions. The different concentration of chromium 0, 25, 50, 75 and 100 ppm was applied. In present study, the overall results suggests the variable response on the rate of seed germination percentage and plant growth of P. glaucum to chromium stress was recorded. Results showed that the chromium treatment at 25 ppm significantly (p<0.05) reduced root growth of P. glaucum. The chromium at 50 ppm level significantly decreased the rate of percentage of seed germination of P. glaucum. The seedling dry weight of P. glaucum seedling was decreased highly at 75 ppm chromium. Root / shoot ratio also decreased due to gradual increase in chromium from low (25 ppm) to higher (100 ppm) levels. Similarly, the chromium at 25 to 100 ppm gradually decreased the percentage of tolerance and seedling vigor index of P. glaucum. An effective efforts for minimize the chromium toxicity and tolerance in plants are required.

“…During growth, plants require a number of essential components from the external environment, including many elements, which are involved in the induction, synthesis and accumulation of phytohormones ( Li et al., 2022 ). For example, Si activates phytohormone signaling mechanisms, Zn and Cu promote plant growth hormone production, and Cr promotes plant jasmonate synthesis ( Awasthi et al., 2022 ; López-Bucio et al., 2022 ; Khan et al., 2023 ). Accordingly, on the basis of the previous study, this study further analyzed the interactions among tea tree leaves physiological indexes, characteristic elements, hormones and physicochemical indexes in soils with different pH.…”

Soil acidification is very likely to affect the growth of tea trees and reduce tea yield. In this study, we analyzed the effects of soils with different pH on the physiological characteristics of tea leaves and determined the multi-element content and hormone metabolomes of tea leaves by ICP-MS and LC-MS/MS, based on which we further analyzed their interaction. The results showed that increasing soil pH (3.29~5.32) was beneficial to increase the available nutrient content of the rhizosphere soil of tea tree, improve the antioxidant enzyme activity and photosynthesis capacity of tea tree leaves, and promote the growth of tea tree. Orthogonal partial least squares discriminant analysis (OPLS-DA) and bubble characteristics analysis were used to screen key elements and hormones for the effect of pH on tea leaves, which were further analyzed by redundancy analysis (RDA) and interaction network. The results showed that an increase in soil pH (3.29~5.32) favored the accumulation of seven key elements (C, K, Ca, Mg, Mn, P, S) in tea tree leaves, which in turn promoted the synthesis of six key hormones (salicylic acid, salicylic acid 2-O-β-glucoside, tryptamine, 2-oxindole-3-acetic acid, indole-3-acetic acid, trans-zeatin-O-glucoside). It can be seen that the increase in soil pH (3.29~5.32) enhanced the resistance of the tea tree itself, improved the photosynthesis ability of the tea tree, and effectively promoted the growth of the tea tree.
