Abstract Background Exogenous hormone applications modify the plant growth and development by inducing changes in their endogenous contents. However, it is not clear whether the effects of exogenous hormones on growth are direct or related with changes induced in endogenous hormones. Laboratory and greenhouse experiments were conducted to study the effect of exogenous salicylic acid (SA) or indole acetic acid (IAA) on endogenous levels in soaked seeds, 5-day-old seedlings, and in vegetative growth of foliar-sprayed plants. The effects of different concentrations of two hormones on germination and growth of maize were also studied. Results The effect of presoaking maize seeds in solutions of SA or IAA (0, 0.25, 0.5, 1, and 2 mM) on their endogenous contents in soaked seeds or in 5-day-old seedlings. Soaked seeds absorbed more SA than IAA. In young seedlings, the majority of two hormones which absorbed during seed soaking remained in the residual seeds. Presoaking seeds in SA or IAA solutions suppressed the growth of 5-day-old seedlings. In the greenhouse experiment, endogenous SA and IAA increased after spraying two compounds at 0.25–2 mM, peaking 2 days after treatment then decreased on. However, plants treated with SA at 1 mM or 2 mM continued to pose higher levels of endogenous SA, 8 days later. At 20 days after treatments, all tested concentrations of two hormones significantly increased the fresh and dry weights of the whole plant. These inducing effects disappeared 40 days after spraying. Conclusion The obtained results demonstrated the changes in endogenous SA and IAA in soaked seeds, seedling, and foliar-sprayed plants due to their exogenous application. However, concentrations of two hormones did not produce any permanent enhancement effects on germination and plant growth.

Gladiolus is commercially propagated through corms and occurrence of dormancy in freshly harvested corms creates hindrance in their cultivation. Present study was designed to compare the effect of different chemicals to alleviate the dormancy of corms in a short time. Gladiolus corms were collected from two growing sites and subjected to chemicals methanol, benzylaminopurine (BAP), gibberellic acid (GA3), indole acetic acid (IAA), salicylic acid, potassium nitrate and thiourea at different concentrations alone or in combinations. The treated corms were planted on sand and placed under dark conditions at 26°C. The treatment of 60% methanol in combination with 0.9 mM BAP showed maximum germination (72.71%). Descaled corms showed 85% germination compared to 60.42% scaled corms, while the corms collected from Faisalabad showed better germination 83.75% compared to corms from Rawalakot (61.67%). The application of 60% methanol also induced 29.65% and 42.43% deterioration in scaled and descaled corms, respectively. The treatments of 0.3 mM BAP in combination with 0.6 mM GA3 exhibited 88.33 % germination in corms collected from Faisalabad as compared to 55% in corms from Rawalakot. Overall, application of BAP and GA3 in combination was found effective in shortening the period of dormancy in both cultivars of gladiolus compared to other tested chemicals or growth regulators.

Phytochemical Constituents

Indole acetic acid (IAA) and salicylic acid (SA) are plant bioregulators that stimulate the desired growth and quality response in crops. This study examined the impacts of IAA or SA seed pre-treatment on phytochemical constituents and antioxidants potential in three genotypes of tomato plant. The results indicated that IAA and or SA treatments increased height of the three genotypes of tomato significantly (P ≤ 0.05) when compared with the control group. Lycopene, total flavonoid and phenolic contents of genotypes F2 cobra and panther 17 F1 treated with 40, 80, and 120 mg/L concentrations of IAA, respectively increased significantly as compared to the control group. Furthermore, IAA and or SA significantly increased H2O2 scavenging activity of F1 KIARA by 5.0% compared to the control (0.2%). Genotype F1 KIARA treated with IAA and or SA (80 and 120 mg/L) had a significant increase in DPPH scavenging activity by 55.0% and 53.0% respectively, relative to control group (11%). The Fe2+-chelating activity of IAA-treated (80 mg/L) F1 KIARA and F2 COBRA increased by 56.0% and 17.0%, respectively compared to the control. The synergistic effect of IAA and SA showed a significant effect on phytochemical constituents and antioxidant potential than individual treatment. The results showed that IAA application or in combination with SA could be used as an alternative bio-stimulant to improve the quality of tomato.

Root And Shoot Growth

Indole acetic acid is a natural phytohormone which influence the root and shoot growth of the plants. Six (GM1-GM6) endosymbiotic bacteria are isolated from Gracilaria corticata and screened for the production of IAA out of six, three bacterial strains GM3, GM5 and GM6 produced significant amount of IAA 102.4 µg/ml 89.40 µg/ml 109.43 µg/ml respectively. Presence of IAA in culture filtrate of the above strains is further analyzed and confirmed by TLC. As these bacterial strains, able to tolerate the high salinity these can be effectively used as PGR to increase the crop yield in saline soils.
