“…The results are corroborated by the earlier findings reported by [7,8]. The comparatively higher leaf area index recorded with GA 3 foliar spraying could be due to its ability to promote plant growth and development as a result of higher photosynthetic rate and efficient use of photosynthates The results are supported by Baraskar et al, [5].NAA is a potent auxin known to stimulate cell division, enhance photosynthetic activity, and accumulates of metabolites in the cell which might have reflected in more augmentation of several s nodes on the main stem as compared to GA 3 and BAP [9,10]. NAA is a well-known auxin that increases cell division and cell enlargement which might have increased the number of nodes and number of branches on the main stem and improved mobilization of photosynthates in the plant leading to the production of thicker stems.…”

A field experiment was carried out to evaluate the effects of BAP, GA3, and NAA on flowering and growth attributes of okra (Abelmoschus esculentus L. Moench) cv. Arka Anamika at the Instructional farm, Agricultural Research Station, Jodhpur Rajasthan during Kharif, 2020. Three treatments each of BAP@ T1-25, T2-50, andT3-75(ppm), GA3 @T4-25, T5-50, andT6-75 (ppm), and NAA @ T7-25, T8-50, and T9-75 (ppm)were used besides controls i.e. T0 with water spray. These three growth regulators were found to enhance early flowering. Other parameters of growth were also found to be increased by treatments with plant growth regulators in okra. Among the growth parameters, the highest inter-nodal length (6.68 cm), plant height (156.4 cm), and leaf area index (3.1) aswas recorded with GA3 @ 75 ppm treatment, whereas maximum stem diameter (43.88 mm), number of branches per plant (5.10) and number of nodes on the main stem (25.05) were recorded with NAA @ 75 ppm. The minimum number of days to the appearance of first flowering (35.50), 50% flowering (41.80), and node on which the first flower appeared (3.82) were also recorded with NAA @ 75 ppm.

“…In tomato, it observed that when it was treated with 80 ppm GA3 and 100 ppm NAA, the maximum fruit yield (483.6 q/ha and 472.2 q/ha) was obtained reported (Prasad et al, 2013). 2% DAP was sprayed at 35 and 70 days after the transplanting in green chilli, observed that minimum days required for the fruit set (25 days), highest length (6.32 cm) and diameter (6.32 mm) of the fruit, number of fruits per plant (142.32), total fruit yield (31.31 t/hectare) (Singh et al, 2015). In treatment of tomato different hormones combination used are GA3, NAA and 2, 4-D at specific concentration (GA3 at 30 ppm, NAA at 30 ppm and 2, 4-D at 5 ppm) showed an effective result by increase the weight of fruit and increases total yield up to 523 q/h in tomato (Tomar et al, 2016).…”

The word auxins means to grow or to increase which mainly act with the development or the growth of the shoot (Smit et al., 1931). It is a natural substance which work as a growth promoter towards the longitudinal axis of the Hormones are signal molecules that are naturally occurring plant growth substances, as well as synthetic compounds and chemical substances. Plant hormones are major growth regulating hormones such as auxin, gibberellin, and cytokinins. However, few plant hormones also work as growth inhibitor such as ethylene and abscisic acid. PGRs play important role in the whole life cycle of plants include plant growth, development, flowering, fruiting , ageing, senescence, color enhancement of fruits, prevention or promotion of stem elongation, leafing, leaf fall. Auxin and gibberellin are used for increasing crop grain productivity, increasing higher yield in leafy vegetables, to increase the size of fruits and vegetables and to make them look attractive for consumer and to improve the agricultural production. The residues of PGRs (auxin, gibberellin) in agricultural products are seriously detrimental to human health because they have been found with hepatotoxicity, nephrotoxicity, genotoxicity. Furthermore, PGRs are suspected to disrupt the function of human and animal reproductive systems. Therefore, there is a need to check the overdoses of these regulators in agriculture production for further ensuring food safety. Several techniques are used to detect the residue of these regulators such as LC-MS, HPLC, GC-MS, Immunoassays techniques (radioassay, enzyme-linked immunosorbent assay). ARTICLE INFO
