The effects of 28-homobrassinolide (HBL) on nickel uptake, protein content and activities of antioxidative enzymes were determined in the seedlings of Brassica juncea L. The seeds were treated with different concentrations (0, 0.01, 1 and 100 nM) of HBL for 8 h and then sown in the Petri plates containing various concentrations (0, 25, 50 and 100 mg dm−3) of nickel. After 7 d, observations were made on shoot and root length, Ni uptake, protein content and activities of antioxidative enzymes… 
Seed Presoaking Treatment of 28-Homobrassinolide Modulates Antioxidative Defence System of Brassica juncea L . under Zinc Metal Stress
In the present study, the effects of seed presoaking treatment of 28-homobrassinolide (28-HBL; 0, 10, 10 and 10 M) were investigated on growth (shoot length and number of leaves), protein content and
Effect of 24-Epibrassinolide on Antioxidative Defence System Against Lead-Induced Oxidative Stress in The Roots of Brassica juncea L. Seedlings
Lead (Pb) toxicity causes oxidative stress by increasing the production of reactive oxygen species. The aim of the present study was to investigate the role of 24-epibrassinolide (24-EBL) on the
Presoaking Seed Treatment of 24-epiBL Modulates Cr Stress in Brassica juncea L .
Pre-sowing treatments of 24-epibrassinolide improved the growth and enhanced the activities of antioxidative enzymes and protein content in leaves of B. juncea plants.
Interaction of 24-epibrassinolide and salicylic acid regulates pigment contents, antioxidative defense responses, and gene expression in Brassica juncea L. seedlings under Pb stress
The results reveal that Pb metal toxicity caused adverse impact on B. juncea L. seedlings, but pre-soaking treatment with EBL and SA individually and in combination help seedlings to counter the ill effects of Pb by improving growth, contents of pigment, and modulation of antioxidative defense system.
Synergistic effect of 24-epibrassinolide and salicylic acid on photosynthetic efficiency and gene expression in Brassica juncea L. under Pb stress.
Presoaking treatment with the combination of EBL and SA for metal-stressed plants mitigated the adverse effects of metal stress by improving growth and levels of pigment and phenolic compounds.
Responses of growth and antioxidative enzymes to different Ni concentrations in castor bean (Ricinus communis)
A pot culture experiment was conducted to investigate the effect of different levels of nickel on growth and biochemical parameters of castor bean (Ricinus communis L.). Castor seedlings were grown
The Effect of Nickel Exposure on Oxidative Stress of Vicia faba Plants
Heavy metal contamination is a serious threat for terrestrial ecosystems. Thus, they could be accumulated in living organisms leading consequently to harmful consequences. In this context, the
24-Epibrassinolide maintains elevated redox state of AsA and GSH in radish (Raphanus sativus L.) seedlings under zinc stress
The results of present study clearly demonstrated that external application of EBR modulates the AsA and GSH redox status to combat the oxidative stress of Zn2+ in seedlings via the As a–GSH cycle and glutathione metabolism as an antioxidant defense system.
Influence of 24-epibrassinolide on seedling growth and distribution of mineral elements in two maize hybrids
It was found that hybrids react differently to exogenously applied hormone, and find­ings suggest that maize hybrid seedlings treated with lower concentrations of 24-EBL could survive and be successful in polluted areas.


The effect of 24-epibrassinolide (24-epiBL) on seedling growth, metal uptake and accumulation were investigated in seedlings of Brassica juncea L. cv. PBR 91. Seeds of B. juncea treated with
Influence of a Brassinosteroid Analogue on Antioxidant Enzymes in Rice Grown in Culture Medium with NaCl
We studied the effects of a polyhydroxylated spirostanic brassinosteroid analogue (BB-16) on the activities of antioxidant enzymes in rice seedlings grown in vitro in culture medium supplemented with
Effects of 24-epibrassinolide on seed germination, seedling growth, lipid peroxidation, proline content and antioxidative system of rice (Oryza sativa L.) under salinity stress
24-epiBL treatment considerably alleviated oxidative damage that occurred under NaCl-stressed conditions and improved seedling growth in part under salt stress in sensitive IR-28 seedlings.

Effects of 28-homobrassinolide and kinetin and especially HBR increased the activities of nitrate reductase and carbonic anhydrase, chlorophyll and total protein contents and net photosynthetic rate in the leaves and pod number and seed yield, at harvest.
Influence of Brassinosteroids on Antioxidant Enzymes Activity in Tomato Under Different Temperatures
The effect of brassinosteroids (BRs) on catalase (EC, peroxidase (EC and superoxide dismutase (SOD, EC activity in tomato leaf discs was analyzed at 25 and 40 °C. Tomato
Effects of 24-epibrassinolide on growth and metal uptake in Brassica juncea L. under copper metal stress
There was an improvement in the shoot emergence and plant biomass production under the influence of pre-germination treatment of 24-epibrassinolide (24-epiBL), and 24-EPiBL blocked copper metal uptake and accumulation in the plants.
Summary. The involvement of ionic channel/s in signal transduction and the amplification of phytohormones induced impact on the processes leading to seed germination provoked us to undertake the
Salicylic Acid Alleviates the Cadmium Toxicity in Barley Seedlings1
The results support the conclusion that SA alleviates Cd toxicity not at the level of antioxidant defense but by affecting other mechanisms of Cd detoxification.
Brassinolide Amelioration of Aluminum Toxicity in Mungbean Seedling Growth
Results showed that BL had promoted growth of mungbean seedlings under Al stress, and the most significant promotive effect of BL on morphological traits and chlorophyll content seems to depend on the addressed traits, BL concentration, and Al stress.
