“…The presence of leaves is an important feature for rooting, especially when using herbaceous or semi-hardwood stem cuttings, because adventitious roots initiation and development are dependent on auxins, carbohydrates, and rooting cofactors that are supplied primarily by the leaves on this type of propagules (BONA and BIASI, 2010).…”

Passiflora actinia Hook (common name: ‘maracujá do mato’) is an important medicinal species due to significant sedative and anxiolytic activities. In order to commercially exploit the plant, however, studies on propagation to improve rooting in stem cuttings are needed. The present study was designed to evaluate the effect of the brown seaweed (Ascophyllum nodosum (L.) Le Jol.) extract when applied on P. actinia stem cuttings bases. Five concentrations of the extract in distilled water were evaluated: 0% (pure distilled water), 10%, 20%, 30% and 40%. The experimental design was completely randomized with 4 repetitions and 12 cuttings per experimental unit. Cuttings were evaluated 45 days from planting. Data were analyzed through polynomial regression analysis and Pearson’s correlation coefficients were calculated for all the variables. On average, 51.27% rooting was achieved. Rooting percentage increased linearly according to the brown seaweed extract concentrations. When compared to the control treatment, about 10% increase in rooting was observed at the treatment with 40% seaweed extract. Leaf retention response to A. nodosum increasing concentrations was also adjusted in a positive linear model. A 15.6% increase in leaf retention was observed at the 40% seaweed concentration when compared to the control. Positive correlations were observed for leaf retention and rooting percentage and leaf retention and roots length. The immersion of P. actinia stem cuttings bases in A. nodosum extract at a concentration of 40% promote positive effects on rooting and facilitate the species propagation.

“…Early root formation is hormonally controlled and the reserves present in the cuttings and photoassimilates produced in the leaves influence its development (Solis et al, 2017). Root initiation and development are dependent on auxins, carbohydrates, nitrogen compounds and rooting cofactors that are supplied by the leaves and accumulate cutting base, in this sense, as a general rule, the presence of leaves is important when used herbaceous or semi-hardwood cuttings for plant propagation (Bona and Biasi, 2010). In a previous experiment with hop herbaceous cuttings, the presence of leaves was associated with the ability to accumulate carbohydrates and to stimulate rooting especially in conditions of intermittent misting and high light intensity (Howard, 1965).…”

“…In H. lupulus L., the success of leafy stem cuttings in rooting is probably associated with their ability to accumulate carbohydrates during the rooting period through photosynthesis (Howard, 1965). Rooting of stem cuttings is also influenced by endogenous auxin produced in the leaves and buds (Bona and Biasi, 2010;Dias et al, 2015).…”

Hop (Humulus lupulus L.) is a plant with economic importance due to its use in the brewing industry. The cones produced by the species contain the main substances responsible for the beer’s bitterness and aroma. Hop plants cultivation in Brazil is still incipient and information on efficient methods for its propagation in this context are scarce. The objective of the present study was to evaluate the effect of different leaf areas (two whole leaves, two leaves in half, one whole leaf, one leaf in half and without leaves) in herbaceous stem cuttings planted in environments with and without intermittent misting. The experiment was conducted in a greenhouse in Curitiba-PR, Brazil (25º25’40 “S and 49º16’23” W). After 30 days of planting, the survival, rooting, sprouting and leaf retention percentages, roots number, average roots length and roots and sprouts dry mass were evaluated. Cuttings with one or two whole leaves and two leaves in half in the misting environment showed the highest rooting percentages (between 90.0 and 97.5%). In the without misting environment, the highest values were observed in cuttings with one or two leaves in half and one whole leaf (between 62.5 and 72.5%). Leafless cuttings had low survival percentages (2.5% in both environments). Under intermittent misting conditions it is recommended to prepare stem cuttings with one or two whole leaves and, in the absence of control over the environment humidity, cuttings with one whole leaf are recommended.

“…It was noticed that maintaining higher number of leaves was beneficial and 2/3 leaf retention was found to be most suitable for obtaining better rooting percentage. 51 In Salacia oblonga, highest regeneration percentage (72.3%) was observed, when leafless cuttings were used as against cuttings with leaves (55.5%) at 300 ppm IBA. 6 In one case, rooting and successful establishment in patchouli (Pogostemon cablin) was found to be superior with 6 leaves + IBA (2000 mg/l), 52 while other report suggested use of 2-4 leaves + IBA (150 mg/l) combination.…”

A Review on Clonal Propagation of Medicinal and Aromatic Plants through Stem Cuttings for Promoting their Cultivation and Conservation

Plant based drugs are being popularized in recent past owing to their long-term benefits without causing side effects. Medicinal and aromatic plants are major sources of these drugs, whose quality is largely dependent on active ingredients present in them. Today alarge number of species are on the verge of extinction due to unscientific management practices, over-exploitation, destructive harvesting, poor seed set, low seed viability, pest and disease incidence etc. Hence, there is a great need for their conservation through cultivation for which standardization of propagation methodologiesis of prime importance. Multiplication of these species clonally through cuttings can make their cultivation economicby providing true to type plants that are known to have optimum levels of active ingredients. Rooting of stem cuttings is a crucial step in plant propagation and there is great variability in the rooting ability of different species. Even though propagation through cuttings appears to be the simplest of all methods, its success depends on a number of factors and the present review concerned highlighting their importance in the context of medicinal and aromatic plants multiplication.
