“…Stem cuttings treated with either IBA or NAA did not significantly increase the mean leaf area in both Hoya species. This finding is in contrast to the results obtained by previous studies ( Abidin & Metali 2015 ; Matali et al . 2017 ) whereby IBA or NAA significantly improved the mean leaf area of Dillenia suffruticosa (Dilleniaceae) cuttings compared with control.…”

Hoya imperialis (H. imperialis) and H. coronaria (Apocynaceae) are known to have ornamental value due to their beautiful flowers; however, the feasibility of propagating these plants have not been reported despite the wild populations in Brunei Darussalam being highly threatened due to habitat loss and overcollection. Thus, the present study aimed to conduct a preliminary study of the feasibility of two alternative propagation methods, stem cutting and micropropagation, as a potential approach for their ex situ conservation. Hoya stem cuttings were treated with either indole-3-butyric acid (IBA) or 1-naphthaleneacetic acid (NAA) (0–2000 mg/L), and then propagated onto a mixture of peat moss and perlite. For micropropagation, Hoya leaf explants were cultured onto Murashige and Skoog (MS) agar media that were supplemented with IBA and/or kinetin (KN) (0–10.0 mg/L). This present study shows that both Hoya species were successfully propagated by stem cutting even without hormone treatment. However, interestingly, in H. imperialis, when compared with control, the mean number of new leaves (6.3 ± 1.0) and the mean relative growth rate (RGR) based on stem diameter (0.004 ± 0.0007 cm cm−1 day−1) significantly increased when treated with 500 mg/L NAA and 2000 mg/L IBA, respectively. Meanwhile, in H. coronaria, significantly higher mean number of roots was achieved by treating with 1000 mg/L NAA (16.6 ± 1.4) or 2000 mg/L IBA (17.5 ± 2.7) compared with control. For micropropagation, callus induction was not promising and could only be observed at specific concentrations of both IBA and KN, with H. imperialis appearing to be more responsive towards these hormones in comparison to H. coronaria. The present study showed that stem cutting appeared more feasible in propagating both Hoya species.

“… Abidin and Metali (2015) suggested that high concentration of IBA might be toxic to cuttings and thus reducing rooting ability. The toxicity and inhibitory effect of IBA at high concentrations have also been reported in Clerodendrum splendens (Lamiaceae) ( Jamal et al .…”

“…Minimum days taken for sprout initiation (11.13 days) and number of sprouts per cutting (15.93) was found in tip cuttings planted in soil + sand + cocopeat + VAM treated with 4000 ppm of IBA this is due to interaction effect enhance the utilization of carbohydrates at the base of cuttings through creation of sink and better utilization of photosynthesis and enhance uptake of nutrients leading to early growth. The results were in accordance with Parmar et al (2010) [14] in Bougainvillea; Abidin and Metali (2015) [1] in Martelli Shrub and Adams et al (2018) [2] in Thuja orientalis…”

Among different types of cutting, tip cuttings showed early sprouting, highest number of sprouts per cutting per cutting and length of longest sprout. Subsequently, highest number of primary roots per cutting, secondary roots and length of longest root were found with same type of cutting. Among different levels of IBA, IBA at 4000 ppm resulted in early sprouting, maximum number of sprouts per cutting per cutting and length of longest sprout. Subsequently, highest number of primary roots per cutting, secondary roots and length of longest root were found with same treatment. Among two different media used soil + sand + cocopeat + VAM media recorded early sprouting, maximum number of sprouts per cutting per cutting and length of longest sprout. Subsequently, highest number of primary roots per cutting, secondary roots and length of longest root were found with same treatment.

Response of ‘Bignay’ [Antidesma bunius (Linn.) Spreng] to cutting origins, IBA and BioGroe treatments

The response of ‘Bignay’ [Antidesma bunius (Linn.) Spreng] to the cutting origins and different levels of plant bio-regulators consist of Indole-3-butyric Acid (IBA) and Biogroe treatments were investigated by means of 3 x 9 factorial experiment in Completely Randomized Design (CRD) using an automated mist propagator. Two hundred sixteen (216) healthy seedlings containing 9 nodes each were used in the study. Results revealed that cutting origins significantly increased shoot length but have no influence on the root number, percent rooting and percent survival. The cuttings originated from the bottom portion of the stem recorded the longest mean in terms of shoot length (12.48 mm) including the highest percent survival and percent rooting (82.41%). Highest mean number of roots were observed on the top cuttings (1.93). Indole-3-butyric Acid (IBA) and Biogroe treatments on cuttings have no effects on the different parameters evaluated. The interaction effect between cutting origins and IBA/Biogroe treatments significantly increased the percent rooting and percent survival except the shoot length and root number of Bignay cuttings. Overall, the findings inferred that A. bunius can be propagated by any cutting origin derived from the main stem of the donor plants tested. Cuttings can effectively be induced to produce roots and survive and can be economically mass propagated even without the application of different concentrations of IBA and BioGroe.
