BACKGROUND AND AIMS The aim of this study was to determine the role of nitrogen- and storage-affected carbohydrate availability in rooting of pelargonium cuttings, focusing on the environmental conditions of stock plant cultivation at low latitudes, transport of cuttings, and rooting under the low light that prevails during the winter rooting period in Central European greenhouses. METHODS Ca...

This study was designed to examine the effects of promoting substances on bud retention, rooting and plantlets survival of rooted cuttings on selected tree species using growth promoting substances. Stem cuttings were treated with rooting-promoting substances, planted in plastic pots filled with top soil and arranged using a completely randomized design (CRD) in a screen house. Stem cuttings of...

Shoot tip cuttings of Quercus phillyraeoides A. Gray ‘Emerald Sentinel’ (‘Emerald Sentinel’ oak), in a transitional growth stage between softwood and semi-hardwood, were collected from containerized plants growing under uniform fertility on June 4, 1998. Cuttings were treated with talc formulations of indolebutyric acid (IBA), ranging from 0 to 8000 ppm (0.8%), and placed under intermittent mis...

We examined effects of mist quantity, topophysis (origin of cutting in the crown of 6-year-old trees), maturation state of the donor stock, and time of sticking on rooting and root system quality of cuttings representing five full-sib hybrid larch families obtained with Larix decidua Mill., L. laricina (du Roi) K. Koch, and L. kaempferi (Lamb.) Sarg. (Sieb. and Zucc.) Gord., as parents. Mist fr...

Testing of candidates as clones would greatly benefit breeding of Scots pine (Pinus sylvestris L.), but has not been applied because of vegetative propgation of the species is difficult. With a common interest in Scots pine breeding, forest research institutions from Sweden, Finland, and Latvia (Skogforsk, Metla, and Silava, respectively) joined in a collaborative project to develop pine cuttin...

Semi-hardwood cuttings of ‘Frantoio’(high rooting ability) and ‘Gentile di Larino’(low rooting ability) cultivars were obtained from one-year-old olive shoots sampled in mid-August. Semi-hardwood cuttings w e re dipped in H2O2 (0% control and 3.5% w/v) and IBA (2000 and 4000 ppm) solutions before rooting in greenhouse equipped with an automatic mist system. After 35 days, 50% of semi-hardwood c...

the aim of this research was to evaluate the influence of rooting cofactors including hydrogen peroxide, boric acid and thiamine along with indole-3-butyric acid (iba) on rooting of olive cuttings cv. rashid in autumn 2007 and spring 2008. the study was carried out as a factorial experiment in a completely randomized design (crd) with three replications, and five cuttings in each replication. r...

This paper reports on recent progress in the development of system to group populations of vegetative cuttings. The system is required to assign a classification to cuttings such that they appear uniform after a growing period based on single two-dimensional monochrome images. We have developed a fast segmentation technique that is able to measure plant features and a supervised learning scheme...

Thinnings, improvement cuttings, and other partial cuttings in southern bottomland hardwood forests are generally designed to enhance the growth and development of those species favored for management objectives. Hardwood tree classes and stocking guides can be used as tools to aid in planning and conducting partial cuttings in hardwood forests. Two disadvantages associated with any partial cut...

This rooting study was set up to compare Paradox walnut softwood cuttings from trees which had been: a) propagated through tissue culture, and b) from conventionally grown trees (seedlings). A number of studies on rooting of both hardwood and softwood cuttings of walnut trees have been made by various workers. Although it was reported by Lee, et. al. (1) and others that 100%rooting was obtained...
