“… The positive effect of foliar spraying with ferrous sulfate on all the characteristics of vegetative and flowering growth, and the concentration exceeded 0.4 gm.L -1 of ferrous sulfate in giving the best results for the studied traits. The results of table (7,6,5,4,3,2) showed that foliar spraying with iron sulfate led to a significant increase in plant height, number of leaves, number of branches, diameter of inflorescences, flowering time, and the percentage of iron in the leaves. The reason for this increase may be attributed to: Iron is included in the composition of Ferredoxin, which acts as a carrier of electrons in the process of photosynthesis, and thus leads to an increase in the number of branches and thus an increase in the number of leaves.…”

“…Table (7) shows that the concentration of triacontanol in the foliar spray treatments considerably influenced the amount of iron found in the leaves, with the 15 mg concentration having the greatest effect. The percentage of iron in the leaves increased from the comparison treatment (the lowest percentage) to L -1 (the highest percentage).…”

“…Studies have shown its significant effect on growth, flowering, photosynthesis, protein synthesis, nitrogen fixation, and increased enzyme activity in plants. The effect of triacontaol depends on the concentration used, as low concentrations of it reduce the effect of Plant salt stress [ 6 ] ,and that spraying plants with Triacontanol increases their resistance to water stress, and also improves plant stress resulting from high concentrations of elements, including lead, and has an important effect on seeds, as the treatment of plant seeds with Triacontanol leads to an increase in plant resistance to stresses and increased biomass and photosynthetic rate [ 7 ] . Spraying fertilizer solutions directly onto the plant's leaves is called foliar feeding, and it's done to remedy nutrient deficiencies and promote healthy plant growth.…”

The experiment was carried out during the spring season 2022 in the nursery of the Diyala Agriculture Directorate, to study the effect of foliar spraying with Triacontanol and iron on the growth and flowering of the zinnia plant -1, and denoted by Tr0, Tr5, Tr10, and Tr15 respectively, the research was carried out as a factorial experiment (4 × 4) according to the Randomized Compelet Block Design (RCBD), the research steps began by planting seeds in cork dishes containing peat moss On 3/14/2022, one seed was planted in each eye. The results of the experiment were summarized as follows: The foliar spraying with Triacontanol led to a significant superiority in all studied traits, as the concentration exceeded 15 mg.L-1 by recording the best results for the characteristic of plant height (24.71 cm), number of leaves (29.80 leaves. plant-1), and number of branches (7.80 branch. Plant-1), flowering time (21.00 days), inflorescence diameter (99.13 mm), and foliar spraying with iron sulfate led to a signficant superiority in all studied traits, as the concentration exceeded 0.4 g.l-1 by recording the best results for the plant height trait (26.79 cm).), the number of leaves (26.30 leaves.plant-1), the number of branches (7.22 branches.plant-1), the flowering date (23.76 days), and the diameter of the inflorescence (80.01 mm), while the interaction between the foliar spraying with Triacontanol and iron sulfate 1ed to superiority Signficant in all studied traits, as concentration treatment 15 mg.L-1 and 0.4 g.L-1 excelled by recording the best results for the characteristic of plant height (30.35 cm), number of leaves (30.90 leaves. plant-1), and number of branches (8.00 branches). Plant-1), flowering time (18.00 days), and inflorescence diameter (110.00 mm).

“…Molecular damages are caused by Pb generating reactive oxygen species (ROS) such as hydrogen peroxide (H 2 O 2 ), hydroxyl radicals (OHs) and superoxide radicals (O 2 ) either directly or indirectly [11,12,14]. The stress-induced changes caused by Pb exposure include declines in the growth rate, reductions in biomass, the chlorosis of plant leaves and other biochemical and physiological changes [15].…”

Brassinosteroids (BRs) influence a variety of physiological reactions and alleviate different biotic and abiotic stressors. Turnip seedlings were grown with the goal of further exploring and expanding their function in plants under abiotic stress, particularly under heavy metal toxicity (lead stress). This study’s objective was to ascertain the role of applied 28-homobrassinolide (HBL) in reducing lead (Pb) stress in turnip plants. Turnip seeds treated with 1, 5, and 10 µM HBL and were grown-up in Pb-contaminated soil (300 mg kg−1). Lead accumulation reduces biomass, growth attributes, and various biochemical parameters, as well as increasing proline content. Seed germination, root and shoot growth, and gas exchange characteristics were enhanced via HBL treatment. Furthermore, Pb-stressed seedlings had decreased total soluble protein concentrations, photosynthetic pigments, nutrition, and phenol content. Nonetheless, HBL increased chlorophyll a and chlorophyll b levels in plant, resulting in increased photosynthesis. As a result, seeds treated with HBL2 (5 µM L−1) had higher nutritional contents (Mg+2, Zn+2, Na+2, and K+1). HBL2-treated seedlings had higher DPPH and metal tolerance indexes. This led to the conclusion that HBL2 effectively reduced Pb toxicity and improved resistance in lead-contaminated soil.
