“…Van der Krieken et al [14] reported that "IBA enhances rooting by increasing internal auxin levels". "Treatment of cuttings with increasing concentrations of IBA along with endogenous auxins, improves the rooting percentage in cuttings" as reported by Melgarejo et al [15] and Tanishka Thapa and Vijaya Rawat [16]. These findings align with the results of Kareem et al [17] in guava propagation through single-node cuttings with 3000 ppm of IBA.…”

Guava can be propagated vegetatively through layering, cutting and grafting, in addition to seeds. Among the propagation techniques, cuttings have gained popularity because they produce results in a shorted span of time. Rooting is an essential step in the propagation of guava through cuttings. Nowadays, the most popular technique for growing cuttings in a misty environment is the use of plant growth regulators, especially auxins such as Indole-3-Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA) that promote root growth. The present study was undertaken to assess the influence of plant growth regulators on the rooting of diverse stem cuttings from guava cv. Arka Kiran under mist chamber conditions at the Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu. Two plant growth regulators, IBA and NAA were employed at various concentrations. These regulators were applied to single-node cuttings with one leaf, double node cuttings with two leaves, and herbaceous cuttings. The highest rooting percentage (55.10%), the duration for bud sprouting (21.13 days), and number of leaves (4.83) were observed in single-node cuttings treated with IBA at a concentration of 3000 ppm concentration. Single-node cuttings treated with IBA at 3000 ppm exhibited superior rooting and sprouting performance compared to Naphthalene Acetic Acid (NAA). Among the three stem cuttings, single-node cuttings with one leaf proved to be the most effective for rapid multiplication.

“…The largest number of roots (59.66) and the tallest shoot (8.24 cm) were found in soft wood cuttings treated with IBA at 1000 ppm. Following treatment with 1000 ppm NAA, early sprouting (17.68 days) and maximum root length (12.81 cm) were observed in semi-hardwood and softwood cuttings, respectively [21] . Ayesha and Thippesha (2018) conducted a study to examine the effects of growth regulators on stem cutting roots in dragon fruit.…”

Vegetative propagation via stem cuttings is a widely used technique in horticulture, particularly for clonal multiplication of fruit crops. The utilization of auxins such as naphthalene acetic acid (NAA) and indole-3-butyric acid (IBA) as plant growth regulators has shown great promise in improving the rooting capacity and general quality of stem cuttings. Auxins are essential for initiating and fostering adventitious root production, elongating and accelerating cell division, and controlling the patterning of the root meristem. Numerous studies across various fruit crops, including pomegranate, mulberry, fig, and dragon fruit, have reported improved rooting percentages, increased root quality parameters (root number, length, biomass), and enhanced shoot development when auxins are applied exogenously to stem cuttings. The physiological mechanisms behind auxin-induced rooting involve auxin biosynthesis, polar auxin transport, and downstream signaling cascades involving auxin-responsive genes and regulatory pathways. Optimizing auxin concentrations and application methods is critical for maximizing rooting success, as species-specific responses have been observed. The integration of auxin treatments with other propagation techniques can further enhance the efficiency and effectiveness of clonal propagation methods for fruit crops. Ultimately, the strategic use of auxins represents a promising and economically viable approach to improving the propagation of fruit crops through stem cuttings, contributing to sustainable and efficient horticultural practices.

“…Over all Guava is a hardy plant but the young plants are susceptible to severe frost that can result in mortality. Guava is propagated through sexual method as well as vegetative methods of propagation [3]. Though guava can be successfully propagated by seeds but the vegetative methods of propagation are preferred as through seedling propagation genetic purity cannot be maintained since it can result in genetical variations which can affect the fruit quality, shape size and yield.…”

Aim: Guava (Psidium guajava L.) is a member of the family Myrtaceae and the order Myrtales which is 4th most important crop in India after mango, increasing productivity. Therefore, In addition to Plant growth regulator are required for proper growth, yield and quality of guava. Study Design: The experiment comprised of 10 treatments of different levels of PGR replicated thrice in a Randomized Block Design. The main objective of the experiment was to find out the effect of different PGR on growth, quality as well as to evaluate the yield and yield attributes of guava. Three concentrations of gibberellic acid (GA3) at 100, 150 and 200 ppm, three concentrations of naphthalene acetic acid (NAA) at 50, 100, and 150 ppm, and three concentrations of Brassinosteriods at 200, 400, and 600 ppm. Place and Duration of Study: So, to find out Effect of Plant Growth Regulators and Brassinosteroids on Growth, Yield and Quality of Guava (Psidium Guajava L. Cv. Allahabad Safeda") A field experiment was conducted at the Central Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj, during 2021- 22. Results: Treatment T9, which consisted of the T9 (Naphthalene Acetic Acid (NAA) @150ppm) had the best effect on Plant height (335.7 cm), number of flowers per plant (61.3), fruiting buds per plant (151.8), number of fruits per plant (48.23), fruit weight (137.7 g), Fruit length (5.36 cm), fruit diameter (7.33), weight of pulp/fruit (104.57 g), weight of seed/fruit (6.74 g), total soluble salts (TSS) (10.97○ Brix), vitamin C content (188.52 gm) ,total sugar (8.03), acidity (1.27 %) and yield (33.3 t/ha). Conclusion: According to the present investigation it is concluded that treatment T9 T9 (Naphthalene Acetic Acid (NAA) @150 ppm) was found most effective in terms of growth, yield and quality of Guava (Psidium Guajava L. Cv. Allahabad Safeda").
