Abstract (sommario):

The tensile strengths of graftings between three selected sweet cherry cultivars and five selected cherry rootstocks were determined with an Instron instrument 6, 12, and 18 weeks after grafting and compared with the tensile strength of self-grafted rootstocks and graftings of rootstocks used as scions. The combination of sweet cherry cultivars and rootstocks was selected to provide a range of compatibility based on preliminary work. The tensile strengths of sweet cherry cultivars grafted on different rootstocks never exceeded the tensile strengths of the self-grafted rootstocks. Rootstocks grafted as scions on Prunus avium L. rootstocks and self-grafted rootstocks produced some of the strongest unions tested and also produced union strength much faster than any of the other combinations. The degree of compatibility was quantified and results indicated that if this value was below 0.2, measured 18 weeks after grafting, it corresponded to combinations with major risks of delayed incompatibility.Key words: tensile strength, grafting, compatibility, sweet cherry, Prunus avium.

Abstract (sommario):

<em>Grafting is the most common cocoa propagation technique applied by farmers. One of the factors that determine the grafting success in cacao is the compatibility level between the scion and rootstock. The objectives of this research was to evaluate the grafting compatibility of half-sib family of Sulawesi 01 clone as rootstock with five superior cacao clones i.e. Sulawesi 01, Sulawesi 02, Sca 6, MCC 01, and MCC 02 as scions. The research was conducted at Pakuwon Experimental Station, West Java, at the altitude of 450 m above sea level with Latosol type of soil and B type of climate (Schmidt &amp; Fergusson), from April to September 2015. This research used the randomized completely block design with five treatments of grafting combinations and five replications. Observation was taken at 14<sup>th</sup>, 21<sup>st</sup>, and 28<sup>th</sup> days after grafting on the total percentage of surviving graftings, percentage of sprouting grafting, percentage of grafting that have not sprouted, and bud sprouting rates. Data were analyzed by variance, correlation, and regression analysis. The results showed that the surviving grafting, the sprouting grafting and the rate of sprouting up to the 28<sup>th</sup> days after grafting varied among the scions. Based on the parameters observed, Sulawesi 01, Sulawesi 2, and Sca 6 demonstrated higher compatibility rate compared to </em><em>MCC 01</em> and <em>MCC 02</em>. <em>The results is applicable in seedling provision through grafting techniques in order to support cacao rejuvenation and or rehabilitation.</em>

Abstract (sommario):

Objective: The aim of this retrospective study was to evaluate the outcomes of secondary alveolar bone grafting and late secondary alveolar bone grafting in 66 unilateral cleft lip and palate patients. Materials and Methods: The total patients were 66 unilateral cleft lip and palate patients, out of which 19 patients underwent secondary alveolar bone grafting and 47 patients underwent late secondary alveolar bone grafting. Autogenous anterior iliac crest cancellous bone graft was harvested and used for grafting the alveolar clefts. Radiographic assessment based on Enemark’s scoring according to the marginal bone levels was done on the intraoral periapical radiographs taken 6 months after performing the surgery. Results: Twelve (63%) out of the 19 patients on whom secondary alveolar bone grafting was done achieved score 1 (optimal marginal bone levels), whereas only 12 (25%) out of the 47 patients achieved score 1 amongst the late secondary alveolar bone graftings. Overall results showed, probability, P = .034 (statistically significant). Conclusion: This study reaffirmed the fact that alveolar bone grafting when done in preadolescent age group (secondary alveolar bone grafting) gives better results in terms of marginal bony consolidation and maintaining the continuity of the alveolar arch, but the late presentation (late secondary alveolar bone grafting) should not be the refusal criteria for performing the alveolar bone grafting. Although the latter patients may not be rewarded in terms of bony consolidation as much as the preadolescent patients the potential of successful surgery in them still exists in terms of providing a platform for the dental implant placement, improvement in the soft tissue symmetry and aesthetics of the face.

Abstract (sommario):

The&nbsp;objective of this study was to determine the effects of inverted radicle and hypocotyl grafting methods on potted nursery tree production in chestnut. The study was carried out in greenhouse conditions in 2003&ndash;2004. Newly germinated chestnut seeds and young seedlings of SA 5-1 genotype were used as rootstocks and sprouts with dormant buds of the same genotype were used as scions. Graftings were done at three periods from April to June. Graft success and scion shoot growth were examined to determine a suitable method and time of grafting. It was found in the study that potted chestnut nursery trees could be produced in one year using either of the grafting methods. Better graft success and survival ratio were obtained from inverted radicle grafting. In this method, graft success was 83.6% in 2003 and 96.7% in 2004. &nbsp;

Abstract (sommario):

DFT method was used to calculate the equilibrium geometries, electron structures and first-hyperpolarizabilities of grafted SWCNT (4,4) by organic chromophore stilbene at B3LYP/6-31G* level. ZINDO method was also used to calculate first-and second-hyperpolarizabilities. The calculated results show that stilbene graftings make the energy gap a little reduced and the maximum absorption wavelength red shifted, however grafting of stilbene breaks the symmetry of pure nanotube and lets hyperpolarizability increase obviously. We also found that grafting on tube mouth results in better nonlinear for their better conjugation and amide bond-linking shows bigger hyperpolarizabilities relative to direct bond-linking.

Abstract (sommario):

The scarcity of high-quality water in arid regions like Saudi Arabia necessitates saline water use in irrigation. Sustainable techniques, such as grafting and soilless cultivation, enhance crop resilience and optimize resource use, ensuring long-term agricultural and water sustainability to meet rising food demand. So, this study evaluated grafting’s effectiveness in enhancing the salt tolerance of tomato (Solanum lycopersicum L.) under soilless culture. The experiment tested two salinity levels, two growing media (volcanic rock and sand), and six grafting treatments: the scion ‘Tone Guitar F1’ was cultivated through non-grafting (G1), self-grafted onto itself (G2), and grafted onto the commercial rootstock ‘Maxifort F1’ (G3), which was grafted onto three newly developed rootstocks, namely X-218 (G4), X-238 (G5), and Alawamiya365 (G6). The results indicated that plants performed better at 2 dS m−1, while higher salinity (4 dS m−1) negatively impacted growth. However, grafting under saline stress improved most of the measured traits, excluding fruit quality (vitamin C, titratable acidity, and total soluble sugars). Grafted plants (G2–G6), particularly those grown in volcanic rock at 2 dS m−1, exhibited superior fruit characteristics, yield, water productivity, and leaf calcium (Ca2+) and potassium (K+) content compared to the non-grafted controls (G1). The sand medium generally produced lower values for all the traits, regardless of salinity or grafting. Moreover, grafting under 2 and 4 dS m−1 reduced leaf sodium (Na+) and chloride (Cl−). The best overall performance was provided by the rootstocks X-218 and X-238. Grafting onto salt-tolerant rootstocks is a promising strategy for improving tomato yield and water productivity under saline irrigation in arid and semi-arid regions.

Abstract (sommario):

This thesis takes as its focus contemporary painting, and develops an understanding of painting as a time-based medium. My research project addresses the array of strategies artists employ to produce durational paintings, a term I have coined as a means of referring to paintings that destabilise the traditional idea of painting as a static object, hung on a wall. The medium of painting embraces other mediums, such as performance and installation, to yield durational paintings. These paintings engage people in their production: vitally, they are participatory and are produced through collaboration. Furthermore, these paintings employ materials imbued with particular properties, such as longevity or, conversely, ephemerality. In time-based media collections and in existing histories of participatory and relational practices painting is absent: these omissions are redressed by the present study. Now that painting is time-based, it is ‘live’.

Abstract (sommario):

Bone grafts fill skeletal defects and provide a structure upon which new bone can be deposited. There is no standard method of storing bone prior to grafting, the three main storage regimes being stored fresh frozen at -80°C, gamma irradiated or freeze dried. The initial aim of this project was to determine how osteoblastic cells behaved when exposed to bone treated in the above ways. It was found that sterilisation of bone with gamma irradiation caused cell death in a number of the cells that came into contact with it. Therefore the use of gamma irradiation for grafting is contraindicated, a similar observation was observed for freeze-dried bone whereas cells grew and differentiated on fresh frozen tissue. The second aim of this study was to develop a system whereby bone marrow cells could be expanded in culture and retain their osteogenic potential so that they would be suitable for either coating a bone graft (thus increasing the rate of osseointegration of the graft) or used alone to treat small bone defects. Rodent bone marrow was used in a variety of cultures and bone formation was induced by either BGJ-b medium or ECCM (Endothelial cell conditioned medium). Control cultures were grown in alpha modification minimum essential medium. ECCM was overall found to produce a greater number of cells at the end of the incubation periods studied than BGJ-b medium. BGJ-b medium preferentially selected mineralization over cell proliferation under all of the culture conditions studied (monolayers, collagen gels and organ cultures). This medium would be best suited to forming small pieces of bone rapidly from bone marrow, to fill small bone defects such as those seen in the dental field. ECCM produced large numbers of osteogenic cells, which could potentially be used to coat large bone grafts.

Abstract (sommario):

Alkali-soluble resins (ASRs) were prepared by (i) solution and (ii) emulsion polymerization. All ASRs were synthesized with number-average molar masses < 20,000 g mol-1 and all had 15 wt% methacrylic acid 5 wt% styrene, the remaining 80 wt% was composed of either methyl methacrylate or a combination of methyl methacrylate and ethyl acrylate. All emulsion ASRs were made to 20% solids, with volume-average particle diameters (dv) in the region 30 – 50 nm, with a glass transition temperature of 80 – 120 °C. Emulsion polymerization was the preferred route for ASR synthesis, to allow further studies on their dissolution behaviour. Before their use as colloidal stabilizers, the dissolution behaviour of the ASRs needed to beinvestigated e.g. effect of temperature, molar mass, and composition. Particle size and absorbance measurements were taken during dissolution of ASRs to achieve 100%neutralization and these were shown to have two stages, an apparent particle swelling (whichwas rapid), and a slower, decrease in particle size as water-soluble polymeric material wasdiffusing out of the ASR particles. From this, further interpretation allowed for calculating the diffusion coefficient of the ASR polymer using the Stokes-Einstein equation. Time-domain nuclear magnetic resonance (TD-NMR) was employed to enhance understanding of what is occurring in the ASR particles, and in the aqueous, continuous phase. The final aspect of this project was to use the ASRs prepared as colloidal stabilizers in emulsion polymerizations of butyl acrylate (BA) and butyl methacrylate (BMA) using varying levels and also the effect of adding additional surfactant. The results show that the effect of ASR molar mass, the concentration of stabilizer, and also the impact of the EA-containing ASR greatly influence stability, whereby lower ASR molar mass, higher levels of stabilizer and including EA greatly benefit colloidal stability in PBA latexes. In PBMA latexes, a similar trend was also observed, but, the presence of ethyl acrylate (EA) in the ASR backbone has a detrimental effect on the colloidal stability, caused by the inability of grafting to occur between the ASR and PBMA.

Abstract (sommario):

Impaction grafting for bone stock loss in revision total hip arthroI;>lasty has been used for over a decade. This technique typically involves the insertion of a cemented highly polished stem into impacted morsellised allograft bone. The aim is to compensate for the bone stock loss after failed primary hip arthroplasty and to provide a mechanical and biological scaffold for mechanical support and bone remodelling. The primary objective of this study is to quantify and optimise the graft properties so as to provide maximum supportive forces to the stem, and, at' the same time, to minimise the amount of per.:operative and post-operative femoral fractures. More than 60 parameters that could affect the mechanical properties of graft have been identified. Porcine bone from femoral heads was used in the study which was primarily divided into two parts: fundamental studies of the graft material, and in-vitro mechanical testing to replicate the clinical application of impaction bone grafting. Various techniques of graft preparation including defatting of the graft were investigated. A die-plunger was employed to perform uni-axial compressive testing on the graft at varying strain rates. It was found that defatted' graft demonstrated higher stiffness. Higher rates of loading resulted in increases in stiffness, hoop strain, axial force and Poisson's ratio. Preloading of the graft provided more predictable mechanical characteristics. Cyclic compressive testing showed th~t individual graft particles fractured during compression. In addition, it was found that the graft demonstrated increased viscoelastic properties at higher strain rates. In-vitro mechanical testing was also performed to compare the level of mechanical stability of a cemented polished stem with a larger uncemented polished stem. Composite femora were '' used for this comparison. It was found that the cemented stem showed higher mechanical stability in terms of the level of micromotion and migration, and uncemented stem failed in a catastrophic manner. The study provided information on how various factors contributed to the mechanical behaviour of bone graft and identified parameters that should be used when in-vitro testing of bone graft materials for use in impaction grafting.

Abstract (sommario):

The gas-solid reaction of tetra(neopentyl)zirconium with the surface of Aerosil 200 pretreated thermally at 200°C has been investigated. Consistent with previous investigations of a similar reaction involving deposition of tetra(neopentyl)zirconium from solution, a unique supported organometallic fragment is formed. It was characterized by IR, 13C CP/MAS NMR, XAS and analytical techniques as (&equiv;SiO)2Zr(CH2 C(CH3)3)2. Thermolysis of silica-supported bis(neopentyl)zirconium(IV) at ca. 120°C results in the extrusion of one equiv. of neopentane. The nature of the remaining surface organometallic fragment was inferred, by its reactivity in olefin metathesis as well as by curve-fitting of its EXAFS spectrum, to be neopentylidenezirconium(IV), presumably formed by alpha-H abstraction. This result is analogous to previously established transformations of bis(alkyl) complexes of titanium, vanadium and chromium supported on silica, but was unexpected since earlier reports of the thermolysis of Zr(CH2C(CH3)3) 4 supported gamma-H abstraction and the formation of a zirconacyclobutane intermediate. The alpha-H abstraction occurs with pseudo-first-order kinetics and activation parameters DeltaH&Dagger; = 24(5) kJ/mol and DeltaS &Dagger; = -19(7) J/K•mol. Both the bis(neopentyl)- and neopentylidenezirconium(IV) fragments were found to catalyze polymerization of ethylene, at room temperature without any added cocatalyst. The reactions are pseudo-first-order in P(C2 H4).

Abstract (sommario):

Copolymerisation of ethyl cellulose (EC) with methyl methacrylate (MMA) and vinyl acetate was carried out in solution, using a number of free radical initiators, to form graft copolymers with grafting yields up to 63% and weight average molecular weight about 9 x 104 g mol-1 Graft copolymerisation of MMA and EC appears to involve participation of comonomer charge transfer complexes at the initial stage of reaction, Interaction of EC with the carbonyl group of MMA enhances the electron-accepting ability of EC and promotes the formation of a donor-acceptor complex as matrix, with the resultant generation of a covalent bonded monomer radical, which then propagates in the usual manner to produce EC-g-PMMA. The influence of a number of experimental variables on the grafting efficiency of the EC-g-PMMA reaction, and the properties of the resulting copolymers, was investigated. The initiator has a significant effect on the grafting efficiency, which decreases in the order azobisisobutyronitril>ammonium persulphate>potassium persulphate>Ce(IV) ion. Benzoyl peroxide was found to be unsuitable because it promoted degradation of ethyl cellulose chains. The order of solvent influence on the grafting yield is chloroform>toluene>benzene. The grafting yield is also reaction time and temperature dependent. A2-3 hour reaction time and 40-50°C reaction temperature gives a substantial increase in both reaction rate and the molecular weight of the graft copolymer product. The introduction of PMMA graft side chains onto EC main chains leads to a significant decrease in the radius of gyration in solution, as determined by size exclusion chromatography, compared to linear EC. This finding is explained by the theory of Stockmayer and Fixman in terms of the number and type of long chain graft points in the molecule, Calculation of viscosity of EC-g-PMMA in solution using the Kurata equation gave values in good agreement with the experimentally determined viscosity. A significant result is that grafting PMMA branches onto EC reduces the hydrodynamic volume, and differential scanning calorimetry showed conclusively that increasing PMMA sidechain length reduces the chain flexibility, by reduction of free volume. The glass transition temperature of EC-g-PMMA, produced by using a large excess of MMA monomer and reasonably long reaction time, was shifted to higher temperature with increase of grafting yield and molecular weight. A single glass transition is observed for copolymers made using low initiator concentrations, and two glass transitions are found for higher initiator concentrations. In addition, EC-g-PMMA samples with higher grafting yield are more brittle than those with lower grafting yield. However, both the bending modulus (determined by dynamic mechanical thermal analysis) and elongation at break increase with grafting yield. Our experiments proved that the crystallinity of EC-g-PMMA is less than that of pure EC and greater than that of pure amorphous PMMA. The specific oxygen gas-permeability coefficients of EC-g-PMMA films decrease with increase of grafting yield. The reason is that grafting decreases of hydrodynamic volume. Interestingly, X-ray diffraction showed that the higher the grafting yields of EC-g-PMMA, the higher its crystallinity. Films of EC-blend-PMMA, made by solution casting and examined in cross section using scanning electron microscopy, showed an essentially multiple layer morphology with non-uniform dispersion of PMMA in the EC matrix. Scanning electron microscopy confirmed, as expected, that EC-g-PMMA cast films were homogeneous with no evidence of phase separation. The tensile strength of EC-g-PMMA films was typically about 20% higher than that of EC-blend-PMMA films, and the graft copolymer films exhibited greater oxygen permeability. A new model for graft copolymerisation to EC is proposed. The model provides for the possibility that grafting to EC with 48% ethoxy content can occur at the five OC2H5 groups and one OH group per unit. It was established using NMR spectrometry of EC-g-PMMA and EC-g-Poly (vinyl acetate) that under some conditions the ethoxy groups are the favoured graft sites. The liquid crystalline properties of EC and EC-g-PMMA were extensively investigated. Optical microscopy with crossed polarisers revealed that the relatively short mesomorphic temperature range of ethyl cellulose is extended downwards almost to ambient temperature in the graft copolymer. Low frequency Raman scattering showed that EC-g-PMMA has higher light scattering intensity than EC at ambient temperature. But it was lower than that of EC at 191°C. Moreover, the Jaynes-Cummings model cannot predict the light scattering intensity of EC-g-PMMA as a function of frequency very well, whereas the EIT-Kerr scheme is able to successfully account for the experimental observations. It was found that EC and EC-g-PMMA are pseudoplastic, lyotropic and thermotropic materials whose viscosity in solution is dependent on many factors, particularly on temperature and solution concentration. Both materials show unusual rheological behaviour, including maxima in the isothermal concentration dependence of viscosity. Unmodified EC exhibits thixotropic flow behaviour, whereas grafting PMMA side chains onto EC changes the flow behaviour to rheopectic, which is also typical of PMMA itself. As the temperature and concentration increase, the viscosity increases in response to the transition from an isotropic to an anisotropic state of EC-g-PMMA. Furthermore, experiments on the distinguishing characteristics of EC-g-PMMA indicate that different solvents affect its anisotropic flow behaviour to a greater or lesser extent. In particular, chloroform shows a stronger flow orientation effect than tetrachloroethane on EC-g-PMMA solutions. The rheological behaviour of EC and EC-g-PMMA in the nematic phase is much more complex than that of ordinary polymers or low molecular weight liquid crystals. The Doi theory is usually applicable to ordinary polymers or low molecular weight liquid crystals, but cannot predict shear stress as a function of shear rate; particularly at very low shear rates for EC and EC-g-PMMA. Whereas, the polydomain model is better to account for the observations. Measurements of thermally stimulated depolarisation current showed that EC-g-PMMA has a longer dipolar relaxation time in an electrical field. Molecular dipole motions of EC give a maximum depolarisation current at 138 °C in the glass transition region and another maximum near 200 °C, corresponding to dipolar relaxation in the liquid crystalline phase. EC-g-PMMA shows a broader dipolar relaxation temperature range in the liquid crystalline phase and the depolarisation current maximum shifts to a lower temperature. We have observed that field induced polarisation of EC-g-PMMA is affected by the length of the PMMA side chain, and obeys an interfacial model of the Maxwell-Wagner-Sillars type. It was confirmed by X-ray photoelectron spectroscopy that the length of the PMMA side chain could affect the surface properties. EC-g-PMMA has higher photoemission intensity than EC, and the photoemission intensity and depolarisation current increase with grafting yield.

Abstract (sommario):

A grafting program for creation of beech bark disease-resistant American beech (Fagus grandifolia) has been established in a cooperative agreement between Michigan Technological University and the National Park Service (NPS). The resistant trees are being used in a restoration project at Pictured Rocks National Lakeshore and Sleeping Bear Dunes National Lakeshore. This report provides an overview of the methods for propagation and planting of American beech, with suggestions for refinements including a forest planting trial. Rates of resistance are quantified for target NPS properties based on survey methods. Resistant trees were located and confirmed through field challenge tests to serve as scion donors for grafting. Resistant tree locations and conditions are not presented to maintain security of valuable individuals but are maintained by each property and revisited annually. This report will be used to inform continuing work towards restoring and preserving American beech in the landscape within NPS properties.

Abstract (sommario):

The overall objective of this research was to elucidate the horticultural, pathological, physiological and molecular factors impacting melon varieties (scion) grafted onto M. cannonballus resistant melon and squash rootstocks. Specific objectives were- to compare the performance of resistant melon germplasm (grafted and non-grafted) when exposed to M. cannoballus in the Lower Rio Grande valley and the Wintergarden, Texas, and in the Arava valley, Israel; to address inter-species relationships between a Monosporascus resistant melon rootstock and susceptible melon scions in terms of fruit-set, fruit quality and yield; to study the factors which determine the compatibility between the rootstock and the scion in melon; to compare the responses of graft unions of differing compatibilities under disease stress, high temperatures, deficit irrigation, and salinity stress; and to investigate the effect of rootstock on stress related gene expression in the scion. Some revisions were- to include watermelon in the Texas investigations since it is much more economically important to the state, and also to evaluate additional vine decline pathogens Didymella bryoniae and Macrophomina phaseolina. Current strategies for managing vine decline rely heavily on soil fumigation with methyl bromide, but restrictions on its use have increased the need for alternative management strategies. Grafting of commercial melon varieties onto resistant rootstocks with vigorous root systems is an alternative to methyl bromide for Monosporascus root rot/vine decline (MRR/VD) management in melon production. Extensive selection and breeding has already produced potential melon rootstock lines with vigorous root systems and disease resistance. Melons can also be grafted onto Cucurbita spp., providing nonspecific but efficient protection from a wide range of soil-borne diseases and against some abiotic stresses, but compatibility between the scion and the rootstock can be problematic. During the first year experiments to evaluate resistance to the vine decline pathogens Monosporascus cannonballus, Didymella bryoniae, and Macrophomina phaseolina in melon and squash rootstocks proved the efficacy of these grafted plants in improving yield and quality. Sugars and fruit size were better in grafted versus non-grafted plants in both Texas and Israel. Two melons (1207 and 124104) and one pumpkin, Tetsukabuto, were identified as the best candidate rootstocks in Texas field trials, while in Israel, the pumpkin rootstock RS59 performed best. Additionally, three hybrid melon rootstocks demonstrated excellent resistance to both M. cannonballus and D. bryoniae in inoculated tests, suggesting that further screening for fruit quality and yield should be conducted. Experiments with ABA in Uvalde demonstrated a significant increase in drought stress tolerance and concurrent reduction in transplant shock due to reduced transpiration for ‘Caravelle’ plants. In Israel, auxin was implicated in reducing root development and contributing to increased hydrogen peroxide, which may explain incompatibility reactions with some squash rootstocks. However, trellised plants responded favorably to auxin (NAA) application at the time of fruit development. Gene expression analyses in Israel identified several cDNAs which may code for phloem related proteins, cyclins or other factors which impact the graft compatibility. Manipulation of these genes by transformation or traditional breeding may lead to improved rootstock cultivars. Commercial applications of the new melon rootstocks as well as the ABA and TIBA growth regulators have potential to improve the success of grafted melons in both Israel and Texas. The disease resistance, fruit quality and yield data generated by the field trials will help producers in both locations to decide what rootstock/scion combinations will be best.
