Abstract:
Leaf samples from 12 peach cultivars (Prunus persica [L.] Batsch.) (Early Crest, May Crest, Flavor Crest,Sun Crest, Fayette, Katherina, Loadel, Andross, Everts, May Grand, Firebrite and Fairlane) grafted on four peach root-stocks were analyzed for their nutrient content. The analysis of variance for leaf nutrient concentrations indicated very significant effects and interactions among cultivars and rootstocks. The rootstock effect on the absorption of nutrient elements was higher for Ca, K, P, Mg, N, and lower for Cu, Zn, Fe, Mn, and B. Generally cultivars grafted on GF 677 had higher N, K, Fe, Cu and lower Zn, Mn, and B, while leaves from cultivars grafted on wild seedlings were found to contain higher Mg and lower P, K, Fe concentrations. Leaf B and Ca were higher for cultivars grafted on Sant Julien GF 655/2, while cultivars on Damas GF 1869 had higher P, Zn, Mn and lower N, B, Ca, Cu concentrations. Leaf N was lower for Fayette on all four rootstocks and significantly different from all other cultivars. Leaf P was lower for Everts and higher for Katherina. Lower concentrations were observed in Early Crest for Fe and Zn, in Andross for Mn, and in Loadel for B, while Flavor Crest had higher concentrations of all these elements. Leaf Zn was the highest for Sun Crest on wild seedling and the lowest for Early Crest on the same rootstock. Similarly leaf N was the highest for Katherina on Damas and the lowest for Fayetteon the same rootstock. Also leaf Mg was the highest for Fayette on Damas and the lowest for Fairlane on Damas. Peach tree mortality was the highest for Damas 1869 and lowest for Sant Julien. Also tree mortality was highest for Early Crest and Sun Crest and lowest for May Grand, Firebrite, and Katherina. The observed trends in the leaf nutrient composition, as regards the cultivars, rootstocks and their interactions, emphasize the importance of these factors on a new peach orchard establishment and macro-microelement fertilization.

Abstract:
Fertilizer recommendations for peach cultivation in the southeastern United States were developed decades ago and may not reflect the peach trees’ needs under current cultivation practices. Adequate fertilization for young peach trees induces a balanced vegetative/reproductive growth, ensures efficient resource use, and is environmentally sound. Droughts in the region are becoming more common. Supplemental irrigation for peaches from the time of field establishment serves as insurance in case drought conditions occur and can increase/advance the yield of young peach trees. Our objective was to determine the influence of different fertilizer levels (25, 50, 100, and 200% of the recommended rate), irrigation levels (irrigated vs. non-irrigated), and irrigation systems (drip vs. micro-sprinkler) on nitrogen partitioning and concentration in different organs of young peach trees. The cumulative nitrogen (N) removal per tree was not affected by the different fertilizer levels. Most of the N allocation was accounted for by summer pruning and defoliation (68% of the total N removed). Irrigated trees had higher cumulative N removal after three years than non-irrigated trees, with differences between irrigated vs. non-irrigated trees in most vegetative removal events (winter and summer pruning, and defoliation). Drip-irrigated trees had higher cumulative N removal after three years than micro-sprinkler-irrigated tress, with differences in N removal found in vegetative and reproductive removal events. Differences in N removal were mainly driven by differences in dry weight rather than the N concentration of the organs. These results suggest that different fertilizer levels did not alter the N partitioning in young peach trees, indicating that reduction in fertilizer applications can be done without negative effects. Furthermore, irrigation induced greater vegetative growth, especially under drought conditions, which may result in greater canopy volume and fruit yield compared to non-irrigated trees. Differences between irrigation systems are not consistent; however, drip is more efficient than micro-sprinkler irrigation, with ~38% water savings.

Abstract:
`Coronet' peach on Lovell rootstock was planted near Clemson, S.C., in Dec. 1995 in 4 rows (= reps) 6.1 meters apart with trees 2.2 meters apart in-row. Trees were trained to a Kearney-V. In the 2nd leaf (Aug. 1997), `Ta Tao 5' buds were grafted to half (= 6-tree plot) the trees in each row. These trees received 2 `Ta Tao 5' chip buds infected with Peach Latent Mosaic Viroid (PLMVd) per scaffold at ≈0.75 to 1.15 m above ground. Dot blot hybridization confirmed that the chip buds successfully (100%) inoculated the treated trees, whereas the controls tested negative. Data collected in 2003 included bloom date, tree size, dormant and summer pruning times, fruit maturity date, fruit yield, mean fruit weight, skin color, soluble solids, flesh firmness, titratable acidity, and pH. Flowering and fruit maturity were delayed by ≈4 days in PLMVd-inoculated (PI) trees. PI trees produced larger fruit, but yield was 23% less than that of non-inoculated trees. Both fruit size and yield had been larger in PI trees in previous years. There were no differences in yield efficiency in 2003, but PI trees were 26% smaller in trunk cross-sectional area and 9% shorter. PI trees took 34% and 23% less time to dormant and summer prune, respectively and had 34% and 28% less wood removed by dormant and summer pruning, respectively than control trees. PLMVd increased fruit firmness, and PLMVd fruit lost firmness at a much slower rate. PLMVd did not significantly affect skin color, but PLMVD fruit were slightly less red. Soluble solid levels were higher in PLMVd fruit than control fruit during the first harvest, but were lower by the last harvest. Acidity was significantly higher and the soluble solids to acidity ratio significantly lower in PLMVd fruit. Control fruit had a slightly higher pH.

Abstract:
A rootstock comparison trial for almond was planted in sandy soil near Atwater, Calif., in Feb.1989. The study consisted of five replications of five trees each for six rootstocks, each with two cultivars. The rootstocks were `Nemaguard' peach, `Nemared' peach, `Hansen 536' peach × almond hybrid, `'Bright's hybrid' (peach × almond), `Halford' peach seedling, and `Lovell' peach seedling. Two cultivars, `Nonpareil' and `Carmel', were used with each rootstock. The accumulated kernel production from `Nonpareil' through the 1998 harvest was highest for trees on `Hansen 536', second highest for those on `Nemaguard', and third highest for trees on `Bright's Hybrid'. The accumulated kernel production from `Carmel' was greatest for trees on `Bright's Hybrid' and second highest for those on `Hansen 536'. The hybrids have produced the largest trees, as indicated by trunk circumference, for both `Nonpareil' and `Carmel'. The greater production of trees on the hybrid rootstocks over those on the peach seedling rootstocks was probably a result of their greater size and not that the trees on the hybrid rootstocks were inherently higher-yielding.

Abstract:
Peach [Prunus persica (L.) Batsch (Peach Group)] trees infected with peach latent mosaic viroid (PLMVd) have been associated with phenological changes including delay in bloom, reduced shoot vigor, and early autumn defoliation. In order to further characterize the changes occurring in trees inoculated with PLMVd, total fatty acid content was measured for floral buds during release from dormancy in `Coronet' peach trees. Palmitic (16:0), stearic (18:0), oleic (18:1), linoleic (18:2), and linolenic (18:3) acids were the major fatty acids in dormant and releasing peach buds of both control and PLMVd-inoculated (VI) trees. The degree of unsaturation increased immediately following release from dormancy in both the control and VI trees. However, desaturation of linoleic acid to linolenic acid was significantly inhibited in VI trees, which was accompanied by a concomitant delay in the resumption of growth. The disparity between the control and VI trees in the progression of increased fatty acid unsaturation continued through petal fall. The presence of PLMVd in `Coronet' peach trees slowed membrane fatty acid desaturation during release from dormancy and suggested that metabolic pathways involving fatty acid desaturation were linked to the delayed phenology of the VI trees.

Abstract:
Planting sod beneath peach trees (Prunus persica) to control excessive vegetative growth was evaluated from 1987 to 1993 in three field studies. Peach trees were established and maintained in 2.5-m-wide vegetation-free strips for 3 years, and then sod was planted beneath the trees and maintained for 5 to 7 years. Reducing the vegetation-free area beneath established peach trees to a 30- or 60-cm-wide herbicide strip with three grass species (Festuca arundinacae, Festuca rubra, Poa trivialis), reduced total pruning weight/tree in 5 of 16 study-years and weight of canopy suckers in 6 of 7 study-years, while increasing light penetration into the canopy. Fruit yield was reduced by planting sod beneath peach trees in 5 of 18 study-years; however, yield efficiency of total fruit and large fruit (kg yield/cm2 trunk area) were not reduced in one study and in only 1 year in the other two studies. Planting sod beneath peach trees increased available soil water content in all years, and yield efficiency based on evapotranspiration (kg yield/cm soil water use plus precipitation) was the same or greater for trees with sod compared to the 2.5-m-wide herbicide strip. Planting sod beneath peach trees has the potential to increase light penetration into the canopy and may be appropriate for high-density peach production systems where small, efficient trees are needed.

Abstract:
L-PEACH is a computer-based model that simulates the growth of peach [Prunus persica (L.) Batsch] trees. The model integrates important concepts related to carbon assimilation, distribution, and use in peach trees. It also includes modeling of the responses to horticultural practices such as tree pruning and fruit thinning. While running L-PEACH, three-dimensional (3D) depictions of simulated growing trees can be displayed on the computer screen and the user can easily interact with the model. Quantitative data generated during a simulation can be saved to a file or printed for visualization and analysis. L-PEACH is a powerful tool for understanding how peach trees function in the field environment, and it can be used as an innovative method for dissemination of knowledge related with carbohydrate assimilation and partitioning. In this study, we describe the version of L-PEACH that runs on a daily time-step (L-PEACH-d) and how users can run the model and interact with it. To demonstrate how L-PEACH-d works, different pruning and fruit thinning strategies were analyzed. Regarding pruning, model outputs showed 3D depictions of unpruned trees and pruned trees trained to a perpendicular V system. For the fruit thinning studies, we simulated different intensities and dates of fruit thinning in mature peach trees. Total simulated yield increased with crop load but the opposite was observed for average fruit weight. An optimal balance between simulated total yield and average fruit weight was obtained by leaving 150 fruit per tree. Simulating different dates of fruit thinning indicated that fruit weight at harvest was higher on earlier compared with later-thinned trees. The model indicates that fruit thinning should be therefore carried out early in the season to maximize fruit size. The simulation results demonstrate that L-PEACH-d can be used as an educational tool and facilitate the adoption of suitable cultural practices for efficient production.

Abstract:
In the last years, sustainable horticulture has been increasing; however, to be successful this practice needs an efficient soil fertility management to maintain a high productivity and fruit quality standards. For this purpose composted organic materials from agri-food industry and municipal solid waste has been used as a source to replace chemical fertilizers and increase soil organic matter. To better understand the influence of compost application on soil fertility and plant growth, we carried out a study comparing organic and mineral nitrogen (N) fertilization in micro propagated plants, potted trees and commercial peach orchard with these aims: 1. evaluation of tree development, CO2 fixation and carbon partition to the different organs of two-years-old potted peach trees. 2. Determination of soil N concentration and nitrate-N effect on plant growth and root oxidative stress of micro propagated plant after increasing rates of N applications. 3. Assessment of soil chemical and biological fertility, tree growth and yield and fruit quality in a commercial orchard. The addition of compost at high rate was effective in increasing CO2 fixation, promoting root growth, shoot and fruit biomass. Furthermore, organic fertilizers influenced C partitioning, favoring C accumulation in roots, wood and fruits. The higher CO2 fixation was the result of a larger tree leaf area, rather than an increase in leaf photosynthetic efficiency, showing a stimulation of plant growth by application of compost. High concentrations of compost increased total soil N concentration, but were not effective in increasing nitrate-N soil concentration; in contrast mineral-N applications increased linearly soil nitrate-N, even at the lowest rate tested. Soil nitrate-N concentration influenced positively plant growth at low rate (60- 80 mg kg-1), whereas at high concentrations showed negative effects. In this trial, the decrease of root growth, as a response to excessive nitrate-N soil concentration, was not anticipated by root oxidative stress. Continuous annual applications of compost for 10 years enhanced soil organic matter content and total soil N concentration. Additionally, high rate of compost application (10 t ha-1 year-1) enhanced microbial biomass. On the other hand, different fertilizers management did not modify tree yield, but influenced fruit size and precocity index. The present data support the idea that organic fertilizers can be used successfully as a substitute of mineral fertilizers in fruit tree nutrient management, since they promote an increase of soil chemical and biological fertility, prevent excessive nitrate-N soil concentration, promote plant growth and potentially C sequestration into the soil.

Training and pruning newly-planted deciduous fruit trees is one of the most important steps in developing trees with a strong framework (scaffold branches). Trees with a good framework of branches can support heavy crops without limb breakage and will help to bring the young tree into production at an early age. Selection and arrangement of these branches determines the type of development and growth in later years. The goal of pruning and training is to balance vegetative and fruiting wood growth.

Abstract:
Batticaloa district on the Eastern coast of Sri Lanka has been one of the most disrupted and devastated areas of the island since civil war began in the early 1980s. Ethnically and culturally diverse, the Eastern province has been under the control of different military actors, the Sri Lankan army, the Indian Peace-Keeping Forces, and the LTTE (Liberation Tigers of Tamil Eelam), however, none maintained full control of the Eastern areas until May 2009 when the Sri Lankan Army successfully defeated the LTTE. Exploring the lives of Tamil communities in Batticaloa, this thesis examines the ways in which people make sense of an ‘everyday life’ shaped by conflict. Following the idiosyncratic journey of the researcher through the uncertain environment of escalating conflict and the aftermath of the tsunami, it builds up a larger picture of life, moving between accounts of everyday violence and suffering and more sustained dwelling on the particular people who are actively making it possible to endure by investing in a more humane future. In areas such as Batticaloa, where violence frames the past, present and foreseeable future, resistance in some shape or form has become a way of life. As Foucault (1976, 2003) maintains, violence which is embedded in social and material structures can create an environment where power and control saturate the routines of the ordinary, making its existence appear ‘normal’. However, from this way of life, what may emerge beyond the more obvious signs of violence, is the fact that people do keep pushing forward. Integral to this is the importance of risk, hope, and trust, which, woven through the interactions of daily activity, mark out what is possible and what is not. The chapters in this thesis, explore individuals who, in the spaces between accepted understandings of ordinary and extraordinary, work around the various controls and constraints to forge habitable spaces in which relations of trust and support can be strengthened and the future can be imagined. Starting with a focus on the relationship between personal narrative and history, I trace the experiences of a woman living through poverty, displacement, and loss. From this I suggest that it is the paradoxical existence of violence, risk, fear, friendship, and trust as worked through the endurance of daily interactions that is integral to understanding the texture of everyday life. Therefore, I argue that what can on the one hand look like a hopeless and negative picture of militancy and violence, can also, contain within it, fragments of hope and survival, captured for example, in the work of local people to reclaim space. I also deal with the complexities of the research experience in a violent environment and look at the strategies that people employ to negotiate and minimize risk in contested and militarized spaces. The second part of the thesis examines the meaning of the everyday and the ordinary through the experiences of a widow and group of fishermen, and thus challenges conventional academic writing which relates ‘normalcy’ in violence prone-areas to peace and productivity. Overall, these chapters argue that a capacity for hope, for building trust, safety, and peace, however fragile and tentative, is as much an integral part of a conflict situation as the more obvious capacity for fear and silence.

Abstract:
Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is a polyphagous, invasive, and highly significant pest of mid-Atlantic fruit orchards. Its capacity to invade orchards season-long is believed to be facilitated by the availability of wild host plants near orchards and the high dispersal capacity of adults and nymphs. Interactions between H. halys and its hosts were investigated via laboratory and field experiments. Rearing H. halys nymphs in the laboratory on several of its known wild and tree fruit hosts used alone and in combination showed that peach was much more suitable for nymphal development and survival than was apple, tree of heaven, or catalpa and that nymphal performance was enhanced on mixed host diets. Nymphs reared on different host plant diets yielded adults that differed in protein, sugar or lipid content, offering new insights into plant diet effects on H. halys nutrition. The majority of tree species identified from unmanaged woodlands next to apple orchards in Virginia and West Virginia were known hosts of H. halys. Passive trunk traps were developed to capture H. halys nymphs walking up and down tree trunks and used to measure their temporal patterns of movement onto and off of wild and tree fruit hosts at the orchard-woodland interface via weekly assessments during two consecutive seasons. More upward- than downward-walking nymphs were captured, which may be partially explained by the positively phototactic and negatively geotactic behavior of H. halys nymphs demonstrated in laboratory studies. Most nymphs captured while walking up and down trunks were second instars, although the data also reflected temporal changes in the distribution of instars and temporal variation in the numbers of nymphs captured. A field study to characterize injuries to apple and peach fruit at harvest from feeding by young or older nymphs early or late in the season revealed that feeding by young nymphs early in the season resulted in least injury to both crops. In combination, these studies greatly improve our understanding of the biology and ecology of H. halys in eastern fruit orchards and provide relevant data that will inform the development of ecologically-based management programs for it.

Transformation of marginal land along with an increase of soil degradation processes (e.g. salinization) is moving the agriculture into more unfavorable soils, forcing the development of new management strategies. Subsurface drip irrigation (SDI) and deficit irrigation strategies have been widely studied although it is necessary to evaluate their feasibility and sustainability when applied in soils with limiting physical properties. At the same time, organic soil amendments and oxygation techniques are arising as low-cost soil reclamation methods that could potentially improve the crop performance under such situations. It is of paramount importance to study the effects of these strategies and techniques on soil properties as well as on crop physiology and productivity, but also on some quality parameters of growing importance in the fruit sector, such as fruit storability. The general aim of this thesis was to assess various soil management and irrigation strategies and study their effects on peach and nectarine orchards under limiting soil conditions.

Se realizó la caracterización morfológica, fisiológica y molecular de tres cepas de Beauveria brongniartii: CIPCa18(85), CIPCu1(44) y CIPH1(1), además de evaluar su actividad entomopatógena en Phthorimaea operculella y Symmetrischema tangolias. La cepa CIPCu1(44) presentó conidias redondas, pequeñas y la formación de sinemas, diferenciándose de las cepas CIPCa18(85) y CIPH1(1) que presentaron conidias elipsoidales.

Al evaluar la actividad entomopatógena de las tres cepas en larvas de primer estadío de P. operculella y S. tangolias, se encontró que utilizando 1 x 109 conidias/ml el porcentaje de mortalidad fue hasta del 100%. Se determinó que para P. operculella la CL50 de las cepas CIPCa18(85), CIPCu1(44) y CIPH1(1) fue 2.71 x 105, 5.53 x 105 y 5.19 x 105 conidias/ml y la CL90 fue 6.81 x 106, 1.22 x 107 y 5.97 x 106 conidias/ml, mientras que para S. tangolias la CL50 para las cepas CIPCa18(85), CIPCu1(44) y CIPH1(1) fue 1.16 x 106, 9.37 x 106 y 4.52 x 106 conidias/ml y la CL90 fue 6.01 x 107, 1.46 x 109 y 2.17 x 108 conidias/ml respectivamente. En ensayos posteriores se determinó que la cepas de B. brongniartii necesitaron mayor tiempo (9-10 días) para que las CL50 pudieran causar el 50% de mortalidad a las larvas de primer estadío de S. tangolias mientras que sólo necesitaron 3 a 5 días para causar el 50% de mortalidad en P. operculella. Posteriormente se evaluó cada CL50 y CL90 en huevos, larvas de último estadío y pupas de P. operculella y S. tangolias, encontrándose que todos los estados de desarrollo fueron susceptibles con diferente grado de infección. En todas estas evaluaciones, la cepa CIPCa18(85) presentó la mejor actividad entomopatógena para el control de P. operculella y S. tangolias.
--- The objective of this research was to carry out morphological, phisiological and molecular characterization of three isolates of Beauveria brongniartii: CIPCa18(85), CIPCu1(44) y CIPH1(1). In addition, entomogenous activity was tested in Phthorimaea operculella y Symmetrischema tangolias. Isolate CIPCu1(44) showed shorter and spherical conidia while isolates CIPCa18(85) y CIPH1(1) showed tipical elipsoidal conidia. RAPD technique showed a relation between isolates CIPCu1(44) and CIPLM1 (B. bassiana) with 50.4% of similarity. Patogegenicity test showed that isolates were effective to first instar larves, the use of 1 x 109 conidia/ml caused until 100% mortality for both insects. CL50 for isolates CIPCa18(85), CIPCu1(44) and CIPH1(1) obtained in P. operculella larves were 2.71 x 105, 5.53 x 105 and 5.19 x 105 conidias/ml and CL90 for each isolate were 6.81 x 106, 1.22 x 107 and 5.97 x 106 conidias/ml respectively. CL50 for isolates CIPCa18(85), CIPCu1(44) and CIPH1(1) obtained in S. tangolias were 1.16 x 106, 9.37 x 106 and 4.52 x 106 conidias/ml and CL90 for each isolate were 6.01 x 107, 1.46 x 109 and 2.17 x 108 conidias/ml respectively. In other essays, isolates of B. brongniartii needed more time to kill 50% of S. tangolias larves (9 to 10 days) while isolates of B. brongniartii needed only 3 to 5 days to kill 50% of P. operculella. With CL90, isolates needed about 3 days for both insects. Finally, each CL50 y CL90 of three isolates were tested in eggs, last instar larves and pupae, results showed that all develop stages were susceptible to B. brongniartii. Isolate CIPCa18(85) showed the best entomogenous activity to make control of P. operculella y S. tangolias because it came of the same insect order, we suggest more studies with this isolate in greenhouse.

Abstract:
According to the UN World Tourism Organization’s (UNWTO) rules, this organization’s aim is to promote tourism through economic development, international understanding, peace, security, basic human rights and freedom, and to show respect throughout the world without exception of race, gender or religion. The World Tourism Organization (UNWTO) was founded in 1924 under the United Nations and it has been continuing its activities in Madrid, Spain since 1970. The World Tourism Organization (UNWTO) takes all necessary measures with tourism in order to achieve its goals. The UNWTO pays strict attention to the interests of developing countries in the field of tourism. For this reason, the UNWTO has a close relationship in the tourism field with the United Nations’ authorities and specialized institutions. It deals with the tourism problems of all countries and supports their contributions to tourism by international agreements. On the other hand, the UNWTO is cooperating with the United Nations Development Program and tries to contribute to the activities of this program. All countries are expected to be a member of the UNWTO and adopt its principles, because tourism will make it possible for them to increase National Income and Development. Macedonia hasn’t applied to be a member of this organization yet, but it is important to start the attempts immediately.

Abstract:
Affirmative actions reflect the ideal of achieving equal opportunities and represent the realization of cultural transformations in order to reduce the effects of historically accumulated inequalities. Such actions are capableof implementing greater representation of minority groups in the most diverse domains of public and private activity. In the case of quotas instituted to guarantee minority access to higher education, the reservation of places is one of the forms of social justice that tries to guarantee a minimum level of education for the most disadvantaged, trying to compensate and equalize the opportunities for access to education. This research aimed to analyze the perception of students in the ISECENSA Law course about the affirmative action policy, with an emphasis on the quota modality that promotes the legal reserve of places for the so-called “minorities”. Therefore, the methodology used was qualiquantitative and had as its starting point the bibliographical review to situate the quota policy as an object in the field of socio-legal studies. Documentary analysis of laws on the subject was carried out, as well as field research, through which the questionnaire was used as a data collection instrument to verify the position of ISECENSA law students on the quota policy and to identify whether the students understand the meaning of the quota policy. Thus, 115 questionnaires were applied to students from the 1st to the 5th period of the Isecensa Law course and the data collected showed the students' concern with Social Justice, even with the initial lack of knowledge about the concept of “affirmative action”. In this way, it was possible to analyze the perception of law students at ISECENSA regarding the quota policy and also to promote awareness of the reasons and effects of the implementation of that policy. It is expected then, to contribute to the humanization of educational institutions by encouraging diversity in order to build a society that respects difference, seeking to achieve peace and equality
