“…Tree species seem to differ in their response to different rooting mediums. Shiembo et al (1996) and Ofori et al (1996) show that saw dust produces a higher rooting percentage for Irvingia gabonensis and Milicia excelsa respectively, contrasting the results obtained here with Nauclea diderrichii which produced a higher rooting percentage on fine sand; but in line with Mesen et al (1997), who recorded a better rooting percentage for Cordia alliodora on fine sand than on saw dust. Media with relatively high water content like saw dust are generally associated with higher rates of water uptake in the cuttings (Loach, 1986) and consequently higher rooting percentages.…”

The effects of substrates on rooting of juvenile stem cuttings of Nauclea diderrichii (De Wild & T. Durand) Merrill were investigated in non-mist high humidity propagators. Rooting ability, root development and shoot characteristics were assessed. Nine weeks after setting (WAS) of cuttings, 92% rooted on fine sand, against 73% on saw dust. Callus production was 4.5% and 5.5% on fine sand and saw dust. Cuttings on 2:1 soil/sharp sand mixture died by the second week after setting. Mean results revealed that number of main roots (10.31) on fine sand was significantly higher than on saw dust (5.63) (P = 0.00). A significant difference was observed between the longest main roots on fine sand (7.68 cm) and saw dust (6.68 cm) (P = 0.00). Number of first branch sub roots was significantly higher on fine sand (33) than saw dust (13) (P = 0.05). The longest sub root (6 cm) on fine sand did not differ significantly from that on saw dust (5.43 cm) (P = 0.07). Shoot characteristics, measured 3, 5, 7 and 9 WAS all increased progressively. Highly significant (P < 0.05) correlations were observed for root and shoot characteristics. Nauclea diderrichii cuttings perform better on fine sand than saw dust without hormones.

“…This development could be linked to the understanding that the moringa tree has been found to be enriched with secondary metabolites (Mooza et al 2014), this could probably have played a role in enhancing the rooting process resulting in the non-significant influence of the IBA. Related to this are other stem cuttings research trial conducted with the IBA with the aim of enhancing the rooting production and development but discovering, based on results obtained, the IBA having a non-significant influence (Ofori et al 1996, Oni & Ojo 2002, Akinyele 2010.…”

Growth and development of moringa (Moringa oleifera L.) stem cuttings as affected by diameter magnitude, growth media, and indole-3-butyric acid

Abstract. The acknowledged status of Moringa oleifera L. in sub-Saharan Africa, especially western Africa, has of recent accorded it the significance of being a good source of income to a large segment of many of its populace. Intensification of research into the realization of its full economic potential will be of utmost value to impoverished societies globally. One way to achieve this is the full exploration of all possible means that will facilitate its successful growth, propagation, and domestication. Even though it can be successfully raised through seeds, the high level outcrossing (64.3%) observed is a hindrance to realization of true to type trees. Vegetative propagation can be employed as an option to tackle the noted limitation, ease the cultivation process, and achieve the required realization of its economic potential. Our trial was carried out to study the influence of two growth media and three levels of indole 3-butyric acid (IBA) on root and shoot development in cuttings taken from a coppiced moringa tree existent in Universiti Putra Malaysia. Semi-hardwood cuttings of moringa, of between 20 and 30 mm diameter, cut into 25 cm length, were obtained, rinsed with a fungicide, then dipped, through their basal portion, inside varying levels (0, 1000, 2000, and 3000 ppm) of indole-3-butyric acid (IBA) for between 7 and 10 seconds. The treated cuttings were then transplanted into a polyethylene bags (23 cm × 36 cm), containing two growth media -a munchong series soil (M) and a combination of a munchong series soil thoroughly mixed with biochar (MB) in a 3:1 ratio sequence. The trial was conducted inside a shade house where the humidity of the experimental area was manipulated through a regular daily manual hand sprinkling. Plant height, percentage of primary branch produced, leaf area, and dry matter (DM) were found to be significantly (P<0.05) influenced by variation in stem diameter magnitude, while the diameter of the primary branch and spad chlorophyll content were found to be non-significantly (P>0.05) influenced. The MB growth media was observed to significantly affect the plant height, percentage root number, and root length as compared to the M growth media. For a successful vegetative propagation and subsequent domestication, the MB growth media coupled with a higher stem diameter size are recommended.

RESUMOA hortênsia (Hydrangea macrophylla) é um arbusto semilenhoso de 1,0 a 2,5 m de altura, de folhagem e florescimento decorativos, muito utilizados como flor de vaso e planta para paisagismo. Conduziu-se este trabalho com o objetivo de estudar o enraizamento de estacas de três partes da planta: apical, mediana e basal; em três tipos de substratos: terra, areia e vermiculita, para a formação de mudas. As estacas foram retiradas das plantas matrizes e divididas em segmentos apical, mediano e basal, os quais foram colocados para enraizar em bandejas de isopor, nos substratos areia, terra e vermiculita, em estufa com nebulização. As estacas que apresentaram melhor qualidade de raízes foram as originadas da parte basal do ramo, sendo que o melhor enraizamento foi observado nas estacas colocadas em areia. As estacas obtidas de diferentes partes da planta não se diferenciaram quanto à porcentagem de enraizamento e quanto ao número de brotos formados. Já os substratos que proporcionaram o maior número de brotações foram a areia e a terra. Algumas estacas apresentaram formação de flores, ocorrendo com maior freqüência nas estacas apicais, sem efeito dos substratos. A areia foi o substrato que proporcionou os melhores resultados quanto à qualidade das raízes e porcentagem de enraizamento. O substrato terra foi superior apenas para o número de brotos por estaca, porém não diferenciou estatisticamente da areia. Mudas formadas de estaca da parte basal da planta se mostraram com qualidade superior.Termos para indexação: Estacas, enraizamento, propagação, hortênsia. ABSTRACTThe Hydrangea (Hydrangea macrophylla) is a semi-ligneous shrub measuring 1.0m to 2.5m in height with decorative foliage and flat-topped or rounded clusters of white, pink, or blue flowers widely used as vase or pot flower as well as landscaping plant. The objective of this research work was to study the rooting of stem cuttings obtained from three different parts of the plant: apical, median and basal portions of the stems, in three different types of substrate: soil, sand and vermiculite, for production of new cuttings. The stems were cut from the mother plants and subdivided into apical, median and basal segments, which were then placed for rooting in styrofoam trays containing the three different substrates soil, sand, and vermiculite and arranged inside a growth chamber containing nebulization. The cuttings that presented the best root quality were the ones originated from the basal portion of the stem and sand was the substrate that provided best rooting. The cuttings obtained from the different parts of the plant did not differ as far as percent of rooting and number of sprouts formed are concerned. On the other hand, the substrates that provided highest number of sprouts were sand and soil. Some cuttings presented flower formation, with higher frequency on the cuttings from the apical segment, with no effect from substrate. Sand was the substrate that provided the best results concerning quality of roots and rooting percentage. The soil substrate ...
