Effects of rooting media and indole-3-butyric acid (IBA) concentration on rooting and shoot development of Duranta erecta tip cuttings

Stem cuttings of Atlantic white cedar [Chamaecyparis thyoides (L.) B.S.P.] were collected in early June 1995, divided into two parts (distal tip and proximal segment), and rooted for 12 weeks in shaded containers outdoors. Total rooting was near 80%. Mist intervals of 8 and 15 min yielded the best rooting percentages and the least dieback and injury. Two rooting media were tested, with similar results. Rooting was slightly higher in Spencer-Lemaire Rootrainers (Hillson size), compared to RoPak Multi-pots (#45). More than 90% of the tips rooted, even without IBA treatment. Auxin improved rooting of stem segments, but the difference between IBA at 1.5 and 3.0 g·L-1 was small. Yield of cuttings suitable for transplanting or potting was 80% for tips, 58% for segments. Dividing stem cuttings into two or more parts allows multiplication of rooted propagules from a collection. Chemical name used: 1H-indole-3-butyric acid (IBA).

Number Of Shoots

Frangipani (Plumeria hybrid `Donald Angus') cuttings immersed in hot water (49C for 10 min) followed by 0.8% indole-3-butyric acid (IBA) basal treatment (hot water + IBA) had greater root length and weight compared to the nontreated control, hot water, or IBA treatment alone. Greater percentage of rooting and number of roots per cutting were observed for hot-water-treated + IBA-treated cuttings compared to the non-treated control and hot-water treatment alone. In a second study, Dracaena fragrans (L.) Ker-Gawl. `Massangeana', D. deremensis Engl. `Warneckii', D. deremensis Engl. `Janet Craig', D. marginata Lam., and cape jasmine (Gardenia jasminoides Ellis) cuttings displayed results similar to those observed with Plumeria cuttings. In addition to enhancing rooting, hot water + IBA also stimulated the number of shoots per cutting on anthurium (Anthurium andraeanum Andre `Marian Seefurth'), croton [Codiaeum variegatum (L.) Blume var. pictum (Lodd.) Mull. Arg.], D. marginata, D. fragrans, Plumeria, and ti (Cordyline terminalis `Ti') cuttings.

Rooting Media

A field experiment was conducted at the central nursery of tea extension center of Bangladesh Tea Board in Bandarban during September to November, 2015 to determine the precise concentration of Indole Butyric Acid (IBA) on propagation through stem cuttings of tea. The experiment was laid out in a randomized block design with four treatments of IBA concentrations: 0 ppm (Control), 2000 ppm, 4000 ppm and 6000 ppm and each treatment was replicated four times. Basal part of tea (BT-2 variety) cuttings were dipped in different IBA concentrations for five seconds. Then these cuttings were dibbled into prepared soil mixture as rooting media. Cuttings were exposed to the rooting media for 90 days and then they all were removed carefully to assess the variation of establishment of cuttings. IBA treated cuttings showed better effect on the rooting rate, root length, root number, shoot length and survival rate compared to the control. It was noted that cuttings treated with 4000 ppm IBA produced the highest rooting rate 79.85%, the highest survival rate 57.60% and the highest root length of 4.85 cm followed by treatment 6000 ppm IBA. In case of all parameters, effects of the treatments 4000 ppm and 6000 ppm of IBA were statistically similar. Positive and strong correlation was observed both in rooting rate versus survival rate and root length versus shoot length in IBA treated cuttings. Thus, IBA at 4000 ppm concentration was recommended for establishment of stem cuttings of tea (BT-2 variety) in the nursery.The Agriculturists 2016; 14(2) 124-129

Bougainvillea Glabra

Abstract Cuttings of Bougainvillea glabra were placed in 80-ml (4.9 in3) containers containing rooting medium mixed with various concentrations of biosolids (1, 2.5, 5 and 7.5%) from two sources (Herzliyya and Haifa). Two biosolids-free control media were used (with or without addition of mini-Osmocote fertilizer). Half of the cuttings were treated with IBA. The rooting percentage was improved by adding biosolids to rooting media. Treating cuttings with IBA without biosolids was inferior to some of the biosolid treatments. Root development was significantly stimulated by the biosolids compared with a slow-release fertilizer treatment. However, the effect of biosolids on shoot development was slightly improved. Generally, high concentrations of Herzliyya biosolids showed the best results in rooting and growth, whereas Haifa biosolids were best at lowest concentrations.

Growth Characters

The present investigation was undertaken to study the effect of different concentrations of Indole 3-butyric acid (0, 2000, 4000, 8000 and 10000 ppm), different types of rooting media (i.e. sphagnum moss, coco peat, vermicompost, sphagnum moss + coco peat and sphagnum moss + coco peat + vermicompost) and the interaction of these in different combinations on rooting and growth characteristic of guava, cv. L-49. The results revealed that the exogenous application of Indole 3-butyric acid (IBA) 8000 ppm with media combination of sphagnum moss + coco peat + vermicompost (I3M5) significantly increased the root characters i.e. success percent of air-layers (83.3 %), callus formation (23.7), number of primary roots (24.21) and secondary roots (32.57); and growth characters i.e. number of leaves (48.17), branches (7.92) and sprouts (8.48) and survival percentages (83.18) over the other treatments and control. Among the rooting media, the combination of sphagnum moss + coco peat + vermicompost (M5) produced the highest rooting percentage (71.27), root characters and growth characters during months of July and August.

Culture Parameters

The objective of this work was to establish tissue culture parameters for gene transfer in sweet orange cultivars. Epicotyl explants with different ages were cultured with 6-benzylaminopurine (BAP), kanamycin and hygromycin. Shoots were cultured with alpha-naphthaleneacetic acid (NAA) alone or in combination with indole-3-butyric acid (IBA). The requirement of BAP for shoot development was genotype-specific. Epicotyl explants from 35-day-old seedlings produced significantly more shoots per explant in 'Pêra'. Kanamycin inhibited shoot regeneration for the most cultivars. The percentage of shoots that produced roots in 'Pêra' was significantly higher in medium with NAA and IBA than with NAA alone.
