Growth, hydraulic and transcriptomic responses to high air humidity and the involvement of abscisic acid (ABA)
Innes, Sheona Noemi (PhD Thesis;2021:65, Doctoral thesis, 2021)The aerial environment, which includes relative air humidity (RH), temperature, vapour pressure deficit (VPD) and CO2 availability, affects plant growth and development in many ways. The aerial environment determines ... -
Growth, nutrient content and tipburn in lettuce (Lactuca sativa L. 'Frillice') in response to light intensity and aerial environment
Kusi, Ellen (Master thesis, 2020)The incidence of tipburn in the vegetable cultivation industry has been a major challenge to the Norwegian growers particularly to the growers of Frillice lettuce (Lactuca sativa L. ‘Frillice’). In periods, Norwegian growers ... -
Growth, stomatal responses and postharvest characteristics of Rosa x hybrida : the influence of air humidity and light quality
Terfa, Meseret Tesema (PhD Thesis;2013:77, Doctoral thesis, 2013)Greenhouse production systems are important in the production of vegetables, herbs and ornamentals. Roses are among the most valuable crops in the greenhouse floriculture industry and are produced as pot plants or as a cut ... -
Impact of light regimes on growth and tipburn formation in lettuce (Lactuca Sativa L. ‘Frillice’) and the use of NDVI for early detection of tipburn.
Bang, Herman (Master thesis, 2020)The work in this master thesis was undertaken in order to add to invesitage how light schedules impact the growth and the formation of tipburn in ‘Frillice’ lettuce when grown hydroponically in controlled growth chambers, ... -
Impact of preharvest relative air humidity and postharvest modified atmosphere packaging on cucumber fruit quality
Ali, Haider (Master thesis, 2017)The effect of relative air humidity (RH) was tested on the cucumber (Cocktail, Quarto F1 cultivar) plant growth, morphology and fruit quality in controlled growth chambers. The plants were grown at moderate RH (60%) and ... -
Impact of UV radiation on plant growth and development in different climatic regimes
Roro, Amsalu Gobena (PhD Thesis;2015:19, Doctoral thesis, 2017-07-06)Ultraviolet (UV) radiation has various effects on the growth, morphology, and biochemical composition of plants. Currently, there is an increasing interest in the manipulation of UV radiation in glasshouses, polythene ... -
Influence of compost, vermicompost and digestate on nutrient status and secondary metabolites, Lactuca sativa L. as a model
Niday, Andrew James (Master thesis, 2018)Peat is the most commonly used substrate in greenhouse cultures due to its predictability and performance. Though significant environmental costs and CO2 emissions are associated with harvesting of peat. It is therefore ... -
Molecular dissection of the role of plant hormones in perennial shoot branching
Katyayini, Niveditha Umesh (PhD Thesis;2023:17, Doctoral thesis, 2023)Shoot architecture in deciduous trees is determined by the apical meristems and the lateral branching. The formation of above-ground architecture perennials is regulated by a complex spatial-temporal regulation. For decades, ... -
