Associations between metabolic profile and coagulation ability of bovine milk effect of feeding and lactation stage
(Eesti Maaülikool, 2013)Most of the milk produced in Europe is converted into cheese by enzymatic coagulation. Therefore the coagulation ability of milk is of great economical interest and widely studied trait. Yet, there is no clear genetic or ... -
Biomass production of different green manure crops and their effect on the succeeding crops yield
(Eesti Maaülikool, 2013)As green manure crops and green manure undersows haven’t been comparatively studied in Estonia, the current research is focused on comparing different green manure crops and their cultivation in Estonia – both when pure ... -
Changes in the biochemical composition of apple (Malus domestica Borkh.) fruits depending on rootstock and calcium treatment
(Eesti Maaülikool, 2013)In the Baltic States, the main goal in apple- related research has been to find out the winter hardy rootstocks and cultivars. The focus in yield quality studies has been on apple size, appearance and storability. Different ... -
Dissolved organic matter and its ecological role in large and shallow water bodies
(Eesti Maaülikool, 2013)About 90% of the organic matter in most aquatic systems is dissolved organic matter (DOM) and the rest forms the pool of particulate organic matter. DOM plays a significant role in the carbon and energy cycle of water ... -
Genetic diversity, genotypic structure and vulnerability of native populations of sickle medic (Medicago sativa ssp. falcata) in Estonia
(Eesti Maaülikool, 2013)The thesis addresses three important problems of plant population biology and ecology by studying Estonian populations of sickle medic Medicago sativa L. ssp. falcata (L.) Arcangeli (hereafter falcata), as a model plant ... -
The influence of cultivar and natural enemies on raspberry beetle (Byturus tomentosus De Geer)
(Eesti Maaülikool, 2013)The raspberry beetle (Byturus tomentosus De Geer), which is the main raspberry pest, causes large yield losses and reduces fruit quality of raspberry. Control of the raspberry beetle relies on synthetic chemical insecticides, ... -
Isoprene emission from aspen (Populus sp.) in relation to environmental drivers
(Eesti Maaülikool, 2013)Isoprene is the most abundant biogenic volatile organic compound (BVOC) emitted from a wide range of plant species. Isoprene plays important roles in plant physiology and atmospheric photochemistry. Emission of isoprene ... -
On the relationships between plant litter and the carbon and nitrogen cycles in European forest ecosystems
(Eesti Maaülikool, 2013)The present thesis studies different processes relating plant litter and the biogeochemical cycles of carbon (C) and nitrogen (N) in several forest ecosystems across Europe. This work unites different experiments in ...
