Cecropia is a relatively well-known and well-studied genus in the Neotropics. Methods for the successful propagation of C. obtusifolia Bertoloni, 1840 from cuttings and air layering are described, and the results of an experiment to test the effect of two auxins, naphthalene acetic acid (NAA) and indole butyric acid (IBA), on adventitious root production in cuttings are presented. In general, C...

Nature of Work: Quercus phillyreoides A. Gray (ubame oak) is an attractive, evergreen species indigenous to Japan and China. It grows as a shrub or small tree reaching a height of 6 to 9 m (20 to 30 ft) (3). Although relatively unknown in the United States, it appears Q. phillyreoides has great potential for use in landscapes in the southern United States in addition to being well suited for ur...

Vegetative propagation potentials of stem cuttings of different physiological ages of Gongronema latifolia highly valued for its nutritional and medicinal properties in South-eastern Nigeria was studied during two seasons in Nsukka. A single source of stem cuttings of the different physiological ages (hardwood, semihardwood and soft wood) was taken from a clone in a forest in South-eastern Nige...

The work aimed to study all the possible factors affecting efficiency of plant propagation via stem cuttings. Several factors including type of cutting, culture medium, type and concentration of growth regulators were investigated. These factors were studied on Ficus hawaii as woody tree and Chrysanthemum morifolium as herbaceous plant to investigate the effect of plant type factor. All experim...

Vegetative propagation of pear rootstocks using semi hardwood cuttings The objective of this work was to evaluate the technical viability of the vegetative propagation of the pear rootstocks ‘Taiwan Nashi-C’, ‘Taiwan Mamenashi’ (Pyrus calleryana Dcne.) and ‘Seleção IAC-1’ (Pyrus spp.) using semi-hardwood cuttings. The experiment was conducted in a nursery with an intermittent mist system at the...

using apple clonal rootstocks is necessary for improving crop efficiency in apple orchards. after graftingof apple cultivars on malling rootstocks, the extra parts of the rootstock was used as stem cuttings. apical,middle and basal parts of these shoots were used as cuttings. two propagation conditions, greenhouse andnursery and three concentrations of indole-3- butyric acid (iba) on rooting, c...

Commercial vegetative propagation of oricultural crops requires the segregation of plant cuttings into categories based on size. The cuttings however must be graded when they are planted ("stuck"), at which time the grade of a cutting is not easy to determine. This paper reports on a system that learns to classify cuttings from being shown examples of images of cuttings that have been graded by...
