Effect of rooting hormones and media on vegetative propagation of Bougainvillea

Abstract

The propagation success of bougainvillea through hardwood stem cutting varied with rooting hormones and rooting media. This experiment was carried out to study the effect of rooting hormone and rooting media on hardwood cuttings of Bougainvillea glabra cv. Double Red during April-July, 2021. The treatments were combination of rooting hormones [Indole-3-Butyric Acid (500 mg L-1), Indole-3-Butyric Acid (1,000 mg L-1), Naphthalene Acetic Acid (1,500 mg L-1), Naphthalene Acetic Acid (3,000 mg L-1), Rootex C] and different rooting media (soil and farmyard manure, sand and farmyard manure, sand and cocopeat) in 1:1 ratio. Cuttings without rooting hormones served as control. We observed earliest sprouting (10.33 days) of cuttings treated with IBA (500 mg L-1) and planted in sand and cocopeat. The highest sprouting percent (100%) and length of longest sprout (49 cm) were recorded when cuttings were treated with Rootex C and planted in sand and cocopeat. The highest shoot fresh weight (10.04 g), shoot dry weight (2.09 g), length of root (13.75 cm), number of roots (34.17), root fresh weight (2.33 g) and root dry weight (0.24 g) was observed in cuttings treated with IBA (1000 mg L-1) and planted in sand and cocopeat. The effect of rooting hormone and rooting media on the diameter of sprouts, rooting percentage, and transplanting success percentage was non-significant. Considering economically important parameters (sprouting percentage and length of longest sprout), this study revealed that sand and cocopeat with Rootex C was the best combination for the propagation of bougainvillea.

Evaluation of propagation of Bougainvillea (Bougainvillea glabra) under different plantation conditions

“…Therefore, in our study we have explored the ways to improve the Bougainvillea propagation. Asexual means are the prime ways to carry out Bougainvillea propagation (Shrestha et al, 2023;Lin et al, 2024), but the vegetative propagation by stem cuttings is the most effective way of multiplying Bougainvillea because of its simplicity and applicability in our country (Memon et al, 2013).…”

An Efficient Method for the Propagation of Bougainvillea glabra ‘New River’ (Nyctaginaceae) from In Vitro Stem Segments

“…However, the plant presents challenges concerning reproduction, as its small pollen tube and low pollen and embryo activity hinder successful pollination, fruit setting, and seed production [10,11]. Consequently, asexual propagation methods, including cuttings, grafting, and crimping, have become the primary means of cultivating this plant [12,13].…”
