“… 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.…”

“…It is famous for its wonderful colors of white, red, yellow, violet, pink and orange [ 2,1 ] , in addition to its landscaping value in gardens, it is considered an antioxidant as it contains flavonoids, peroxidases and peroxidases in the vegetative parts, and is considered one of the favorite plants of bees [ 4,3 ] . Agricultural technical practices for most cultivated plants, especially decorative plants, now include the use of plant growth regulators, which are organic chemical compounds that regulate numerous physiological processes in the plant at low concentrations [ 5 ] , and Triacontanol is one of the natural plant growth regulators found In plant wax, it is used to increase plant productivity and quality. Studies have shown its significant effect on growth, flowering, photosynthesis, protein synthesis, nitrogen fixation, and increased enzyme activity in plants.…”

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).

“…Research has shown that the use of a combination of LOF and PGR in plant cultivation can improve the quality and quantity of soluble sugars, vegetative and generative growth (Suherman et al, 2017;Gao et al, 2020;Kasim et al, 2020). The PGR is directly involved in regulating senescence, flowering, seed germination, regulating physiological processes, and increasing fruit formation (Zahid et al, 2023). PGR increase tolerance to environmental stresses such as drought, cold, and heat, which is due to the production and transcription of anti-stress genes such as heat shock proteins (Noein and Soleymani, 2022).…”

Mineral or inorganic fertilizers are increasingly being used to increase tomato productivity. However, excessive use of inorganic fertilizers may negatively impact soil fertility and microbial activity. To maintain food safety and agricultural sustainability, the use of inorganic fertilizers must be balanced with organic fertilizers. Additionally, sub-optimal land, such as dryland, can be used to optimize tomato productivity, particularly in the North Lombok Regency, Indonesia. This study aimed to investigate the effect and interaction of a combination of liquid organic fertilizer (LOF), plant growth regulator (PGR), and NPK fertilizers as inorganic fertilizers on the growth and yield of tomatoes in dryland. The experimental design was a completely randomized block design, with two factors: the concentrations of commercial inorganic fertilizer (0, 1,300, and 2,600 ppm) and the type of commercial LOF (Bio-Extrim and Organox) + commercial PGR (Hormax). The results showed that the interaction was not significantly different between inorganic fertilizer and LOF + PGR, except for mean fruit weight in the first week of harvest. However, there were differences in responses at the level of each factor. The application of inorganic fertilizer at 2,600 ppm increased tomato productivity by 13.81%. LOF was only significantly different in fruit weight/plant in the first week of harvest and was not significant after that.

“…Among these, drought is a serious threat to plant growth and development, which will result in the over production of highly reactive oxygen species (ROS), such as singlet oxygen ( 1 O 2 ), hydrogen peroxide (H 2 O 2 ), superoxide radical (O 2.- ), and the hydroxyl radical (·OH), causes oxidative damage to protein and lipids, which further leads to irreversible changes in protein structure and function, finally inhibit the photosynthetic process, growth, and yield [ 3 ]. However, exogenous application of PGRs in low concentrations often leads to significant improvements and high yields in fruit trees [ 4 ].And the strategies of exogenous plant growth regulators (PGRs) treatment have been utilized to effectively improve crop drought tolerance and save yield under drought stress [ 5 ]. Moreover, PGRs play critical regulatory functions in plant acclimatization to abiotic stress scenarios and could be handy to rectify the plant metabolism and development as well.…”

Background Due to global warming, drought climates frequently occur on land, and despite being drought resistant, pineapples are still subjected to varying degrees of drought stress. Plant growth regulators can regulate the stress tolerance of plants through hormonal effects. This experiment aims to investigate the regulatory effects of different plant growth regulators on Tainong- 16 and MD-2 Pineapple when subjected to drought stress. Results In this experiment, we examined the regulatory effects of two different plant growth regulators, sprayed on two pineapple varieties: MD-2 Pineapple and Tainong-16. The main component of T1 was diethyl aminoethyl hexanoate (DA-6) and that of T2 is chitosan oligosaccharide (COS). An environment similar to a natural drought was simulated in the drought stress treatments. Then, pineapples at different periods were sampled and a series of indicators were measured. The experimental results showed that the drought treatments treated with T1 and T2 plant growth regulators had a decrease in malondialdehyde, an increase in bromelain and antioxidant enzyme indicators, and an increase in phenotypic and yield indicators. Conclusion This experiment demonstrated that DA-6 and COS can enhance the drought resistance of pineapple plants to a certain extent through bromelain and oxidative stress. Therefore, DA-6 and COS have potential applications and this experiment lays the foundation for further research.
