Abstract:

Thesis (MTech (Horticulture))--Cape Peninsula University of Technology, 2017<br>Transpiration serves in leaf cooling, maintaining turgor pressure, promoting xylem transport of nutrient solutes from roots to shoots and delivering mobile soil nutrients to root surfaces. Soil availability of nitrogen can modulate transpiration rates, consequently powering nutrient delivery to the root surfaces (‗mass-flow'). Although such knowledge on N-regulation of transpiration is available, it remains unknown, however, whether it is NO3- or NH4+ that regulates transpiration. Given that both nitrogen forms co-

Abstract:

The purpose of this reseach project is to answer the question "What are the core communication skills needed for pre-hire training programs in Kentucky." To answer the question the researcher first examined the literature relative to the existing labor pool and then conducted a focus group with unemployed persons. The next phase of the research involved extensive field work, job analysis, and content analysis to determine what core communication skills were common in various Kentucky manufacturing companies. The researcher found strong evidence to establish a core set of competencies that pre-

Transplanting is a common practice for many horticultural crops and some field crops.

The objectives of this present research were to investigate whether transplanting increases external Zn requirements of transplanted oilseed rape, and the mechanisms of root function, growth and Zn uptake after transplanting including rhizosphere modification capacity by plant roots.

Abstract:

In soils and in conventional nutrient solutions, establishing the internal and external boron (B) requirements of plants is often confounded because the external B concentration changes during plant growth. On the other hand, the major problem of working with low B concentrations in conventional nutrient solutions is that these concentrations are quickly depleted as B is taken up by the plant roots. Hence in most conventional solution cultures, the initial B concentration is often very high to ensure adequate supply of B throughout an experiment. This research was carried out to develop a solu

This thesis investigates the symptoms of leaf senescence in response to plant shoot water stress and demonstrates the effect of a non-hydraulic root signal in the senescence response of mature leaves of sunflower. The alleviation of the leaf soluble protein loss rate by excision of the root system in drying soil indicates that this signal originates in roots in dry soil and acts to promote protein loss.

The resource supply to pollinators is highly variable, yet dioecious plants are dependent on pollinators, and dioecious masting requires male and female plants to flower synchronously.

[Truncated abstract. Please see the pdf format for the complete text. Also, formulae and special characters can only be approximated here. Please see the pdf version for an accurate reproduction.] This thesis examines the water use, ecophysiology and hydraulic architecture of Eucalyptus marginata (jarrah) growing on bauxite mine rehabilitation sites in the jarrah forest of south-western Australia. The principal objective was to characterise the key environment and plant-based influences on tree water use, and to better understand the dynamics of water use over a range of spatial and tempo

Abstract:

Water and fertilizers are the two major agricultural inputs limiting yields in the arid and semi-arid regions of the world. Proper knowledge of their influence on crops should be obtained for appreciable returns. Therefore, a field study was conducted to evaluate the effects of four nitrogen (N) treatments (0, 56, 112, and 168 kg N/ha), two water (M) levels (39 and 58 cm), and two varieties (V) (Funks G-522DR and Conlee Rusler) on dry matter production, total N concentration, and yield of grain sorghum (Sorghum bicolor (L.) Moench). Total N concentration, dry matter, and grain yield were incre

Abstract:

Stakeholder satisfaction has in the modern day, become an imperative criterion to achieve project success. Satisfaction of stakeholders’ requirements however is challenging because these requirements evolve as the project progresses. Previous research indicates that as stakeholders continuously interact with a project, they gain more information and new requirements or request for modifications are likely to emerge as a result of this increased intelligence. Nonetheless, conventional project management elicits requirements from stakeholders at the onset of the project, and uses these pre-defi

Abstract:

Mestrado em Arquitectura Paisagista - Instituto Superior de Agronomia<br>Irrigation is an essential factor for the success or failure of the landscape. The adequate design and functionality of an irrigation system is determinant to achieve the quality, economic and environmental targets of the landscape. This report starts with a historical outlook of the relevance of water in the landscape, from Antiquity to the present day, where there is a global crisis of water resources. This fact, along with the aesthetic and economic landscape concerns, is the main reason behind the great present
