Morphological characteristics of rooted cuttings and seedlings of four open-pollinated loblolly pine families cultured at the G.H.W. Weyerhaeuser Nursery near Washington, North Carolina were assessed after lifting. Cuttings were visually assigned to nine grading classes and six putative cull classes. The nine grading classes represented a factorial of three root collar diameter classes (small [...

On the UK Continental Shelf, up to 80,000 tonnes wet weight of oily drill cuttings are produced annually. These are heterogeneous wastes generated from the petroleum drilling industry, composed of significant percentages of hydrocarbons, heavy metals and chlorides. Since 1992, the discharge of drill cuttings containing more than 1% oil-on-cuttings has been prohibited. Moreover, the extensive in...

Androgaphis lineate Nees., an important tribal medicinal plant of the Shevaroy Hill was noted to be restricted in its distribution due to biotic pressure. The species was successfully propagated by stem cuttings in its habitat. The percentage establishment of stem cuttings was 67.

Given n lines in the plane, a (1/r)-cutting is a subdivision of the plane into cells such that each cell intersects at most n/r lines. Cuttings are fundamental to the design of geometric divide-and-conquer algorithms and have numerous applications. Early suboptimal constructions of cuttings were given implicitly in the works by Megiddo and by Dyer in the 80s; simple randomized constructions wer...

We prove a general lemma on the existence of {I/r)-cuttings of geometric objects in Ed that satisfy certain properties. We use this lemma to construct (I/r)-cuttings of (asymptotically) optimal size for arrangements of line segments in the plane and arrangements oftriangles in 3-space; for line segments in the plane we obtain a cutting of size O(r + Ar2/n2 ), and for triangles in 3-space our cu...

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...

Objective: In order to study the effect of different concentrations of IBA hormone on rooting of olive cuttings in spring and winter of 2012-2013 in a greenhouse in Jiroft, Iran. Methods: a split-plot experiment was conducted on the basis of a Randomized Complete Block Design in which hardwood cuttings of one-year-old olive plants cv. Manzanilla with the diameter of 0.7-1 cm were used. The main...

The current experiment was carried out to study the effect of several media including sand, sand+cocopeat, sand+perlite, cocopeat+perlite and sand+cocopeat+perlite on rooting quality of stem cuttings in weeping bottlebrush plant (Callistemon viminalis). The study was done during the late August of 2010. Statistical design was completely randomized with three replications. After wounding the bot...
