Effect of Hormones on Rooting of Apical Cuttings for Propagation of Guava Cv. Lucknow-49

Abstract

An attempt was made on the propagation of Guava cv. Lucknow-49 during the period of 2022-23 from apical cuttings under mist chamber conditions was undertaken. The apical cuttings were collected from shoot tips measuring about 10 to15 cm treated with different hormones of concentrations viz., IAA @ 2000, 3000 and 4000 ppm; NAA @ 2000, 3000 and 4000 ppm along with IBA @ 3000, 4000 and 5000 ppm and these were compared with control, the treated apical cuttings were planted in 40 cavity protrays and kept till 30 days for root induction under mist conditions. The different growth hormonal applications and its varied concentrations excerted a significant effect on root development in cuttings. Apical cuttings treated with IBA @ 5000 ppm was found better for rooting percentage (69.90 %), survival percentage (67.50 %), time taken to root (23.75 days), number of roots per cutting (15.15, 16.25, 17.53 and 24.64) and root length (7.33, 9.78, 13.85 and 18.33 cm) respectively at 30, 60, 90 and 120 DAP, fresh root weight (3.93 and 10.15 g), dry root weight (1.13 and 2.18 g) at 60 and 120 DAP, respectively. The rooting hormone IBA performed better in formation of rooting in apical cuttings when compared to IAA, NAA and untreated control. It can be revealed from the current study that propagation of guava through apical cuttings when treated with IBA @ 5000 ppm was proved as a better propagation method for rooting of cuttings.

Performance of Guava Stem Cutting – A Review of Successful Though Non-commercial Propagation Method

“…(Anonymous, 2020) Production of quality planting material for fruit crop of such commercial importance is essential need of hour (Kumar et al, 2022). Although, it is apparent that despite the rising need of horticultural crops, horticulture sector faces acute shortage of planting material and nursery people cannot meet the requirement (Mohapatra, 2013, Yogesh et al, 2023. In such a scenario, there is anurgent need to develop cost effective protocols, which are rapid and can provide uniform, high quality genetically predictable stocks in desired quantities within a short period of time.Guava is readily propagated by seed but inherent heterogeneity of seedling does not favour its commercialization.…”

“…Joshi, 2024 cuttings with several manipulative treatments viz., wounding, hormonal treatment, growing environment (Siva Prakash et al, 2018, Costa et al, 2019, El-Sharony et al, 2020, Sarjiyah et al, 2021, Vanitha et al, 2023, Yogesh et al, 2023. Although, propagation of guava stem cutting was not so popular method in old days because of its difficult to root nature (Kumar et al, 2022).…”

“…Nevertheless, trail resulted in nonconsiderable result (<10%). Owing to understand mechanism of guava stem cutting more precisely, review has been done of research so far has conducted.While reviewing the rooting success in stem cuttings, highly variable results (7%-70%) are noticeable in guava (Prasad et al, 1988, Yogesh et al, 2023. Such variable results, explain the complexity of propagation through cutting, pointing out the possible reason behind unpopularity of guava stem cutting propagation despite very active research.…”

“…Therefore, to establish guava stem cutting as viable and commercial propagation technique, in depth study of these factors is vital. This paper briefly discusses the research so far has done with relevance to various factors influencing performance of guava stem cutting while indicating possible future research directions for more encouraging and consistent results.In case of cutting,it is well documented that clonal regeneration through cutting is most rapid and least expensive method (Hartman, 1969, Yogesh et al, 2023. Investigations have proved that guava is successfully propagated from stem Guava, stem cutting, plant growth regulator, propagation, Psidium guajava L.…”
