Effects of culture conditions on the photoautotrophic growth and biochemical composition of Chlamydomonas reinhardtii, as a potential source for hydrogen production
Markina, Daria (PhD Thesis;2014:85, Doctoral thesis, 2014)Hydrogen is a particularly attractive energy carrier, since its combustion produces water vapor only. The green microalga Chlamydomonas reinhardtii is able to produce hydrogen under sulfur-deficient anaerobic conditions ... -
Epigenetic effects of temperature during embryogenesis on climatic adaptation traits in Norway spruce (Picea abies) : studies of cold hardiness, gene expression and epigenetic marks
Slågedal, Kaia (Master thesis, 2019)Norway spruce (Picea abies) is known to have an epigenetic memory of temperature during embryogenesis, which affects phenological traits in the trees more than 20 years later. This memory was first shown in trees from ... -
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 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 ... -
Interactive effects of light quality and temperature on bud set and shoot elongation in Norway spruce (Picea ables) and Subalpine fir (Abies lasiocarpa).
Chiang Silva, Camilo Esteban (Master thesis, 2017-06-08)In recent studies, temperature was shown to modulate the response to short days (SD) in woody species. This is an important issue for plant production in zones with marked seasons. Furthermore, light quality affects bud ... -
Sensitivity of plants exposed to gamma radiation : a physiological and molecular study
Blagojevic, Dajana (PhD Thesis;2019:100, Doctoral thesis, 2019)Sessile organisms such as plants need to cope with a range of changing environmental conditions and stressors, including ionizing radiation like gamma, beta or alpha radiation and non-ionizing radiation (UV-A and UV-B ... -
Sensitivity to gamma radiation of Scots pine seedlings grown from seeds developed under elevated levels of ionizing radiation
Rahman, Md Mahfuzur (Master thesis, 2021)As being sessile, plants are generally exposed to background levels of ionizing radiation in their natural environment due to cosmic radiation as well as alpha-, beta- or gamma- emitting radionuclides in naturally occurring ... -
A study of freezing tolerance in red clover (Trifolium pratense L.)
Zanotto, Stefano (PhD Thesis;2022:36, Doctoral thesis, 2022)The ability to tolerate freezing temperatures is one of the traits that allows successful overwintering of red clover (Trifolium pratense L.) at Nordic latitudes. Freezing tolerance (FT) is enhanced during a period of ...
