abstract an investigation was accomplished during 2007 and 2008 to test effect of hormonal treatment and cutting position on rooting of sebri , shekari and natanz cultivars of pear (pyrus pyrifolia.) the experimental design was a two way factorial in a completely randomized method and with pgr5 treatment (iba and iba with naa in four levels in the first year and four higher levels of iba in sec...

We prove that the d-dimensional hypercube, Hd, with n = 2 d vertices, contains a spanning tree with at least 1 ? 2 log 2 n ? o 1 log n n + 2 leaves. This improves upon the bound implied by a more general result on spanning trees in graphs with minimum degree , which gives 1 ? O(log log n) log 2 n n as a lower bound on the maximum number of leaves in spanning trees of n-vertex hypercubes.

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...

background: the sources of radioactivity in the environment have natural, terrestrial and extraterrestrial, and anthropogenic origins. plants may get radioactive nuclides in two ways: (i) by the deposition of radioactive fallout, (ii) by absorption from the soil. materials and methods: the concentrations of the natural radionuclides (226ra, 228ra, 40k) and the artificial radionuclide (137cs) in...

This thesis describes the methods used to analyse and model the cutting of pig carcasses into the products: back, belly, spine and ribs. Automatic pre-processing methods to segment out the individual products from raw DICOM images are developed. A bit resolution reduction method is presented for producing images that are readable for other software. Image registration method are studied and use...

This article highlights the efficacy of plant growth regulators and nutrient solutions on root development and survival of ascending purple milkvetch (APMV) cuttings. Three auxin-like growth regulators and Hoagland solutions were used as root inducing agents. The cuttings were planted in sand medium that allowed evaluation of rooting effectiveness. The study showed that up to 100% establishment...

for vegetative propagation of nemaguard, st julien a, tetra and gf677 rootstocks via cutting, two separate experiments were carried out in a factorial based on completely randomized design. semi hardwood cuttings were taken in late august and then treated with concentrations of zero, 1500, 2000, 2500 and 3000 mg/l iba. cuttings were cultured in perlite medium and in a greenhouse with mist syste...
