Basis for agroecological management of aphids (Aphis craccivora Koch) on cowpea (Vigna unguiculata L.) in Cuban agroecosystems
(Master thesis, 2014-11-04)Aphid (Aphis craccivora Koch) is an important cowpea (Vigna unguiculata L.) pest in Cuban agroecosystems, causing important damages. Aphid fluctuation in a cowpea crop was observed by weekly counting in a control treatment. ... -
Biological control of the cabbage root fly (Delia radicum) using an entomopathogenic fungus (Metarhizium brunneum)
(Master thesis, 2020)Cabbage root flies are a damaging pest to cruciferous crops in the northern hemisphere. They are considered to be the main pest of brassica crops (EPPO, 2004). Their larvae feed on the roots and stems of brassica plants. ... -
Biology and control of the invasive Fallopia taxa
(Master thesis, 2015-05-07)Abstract Fallopia japonica and Fallopia sachalinensis are perennial, rhizomatous plants, native to East Asia, and introduced to Europe in the mid 1800’s. Hybridization between the taxa in the introduced range has given ... -
Celestial ecology : multiple ontologies of plant breeding
(Master thesis, 2017)This study investigates the role that concepts of nature play in contemporary plant breeding practices, primarily in the Wageningen University plant breeding department but also among biodynamic breeders and breeders working ... -
Comparison of vernalization response under natural and artificial climate conditions in Lolium perenne L.
(Master thesis, 2015-11-06)Forage grasses like perennial ryegrass (Lolium perenne L.) and Festulolium are extensively cultivated worldwide and constitute primary feed for ruminants due to their high nutrient value, high palatability and digestibility. ... -
Determining factors and trajectories analysis to support system diversification : mixed orchard animals and mixed orchard vegetables systems
(Master thesis, 2015-11-05)Fruit production is one of the largest users of pesticides among the agricultural productions, consequently leading to detrimental effects for environment quality and human health. In a context of pesticides use reduction ... -
Effect of early and late mechanical treatments in autumn on bud growth and control of Sonchus arvensis in spring cereals
(Master thesis, 2022)Sonchus arvensis is a perennial weed species that causes problems especially in organic agriculture in Northern Europe. It propagates by seeds and creeping roots. In the present study, the effect on biomass and growth of ... -
Fenologisk utvikling i rødkløver
(Master thesis, 2015-02-26)Rødkløver (Trifolium pratense) er en viktig plante i grovfôrproduksjonen i Norge. Det er nær sammenheng mellom fôrvekstenes fenologiske utviklingstrinn og deres fôrkvalitet. Både med tanke på praktisk dyrkingsveiledning ... -
Frukttrekreft på eplegrunnstammer
(Master thesis, 2015-08-06)The apple canker disease (aka European canker), which is caused by the fungus Neonectria distissima, infects apple trees and can cause severe damage on both the fruit and the tree itself. For some time it has been assumed ... -
Fusarium og Microdochium på såkorn - overlevelse ved lagring og betydning for spireevne
(Master thesis, 2015-02-24)I de senere årene har spiringsfusariose forårsaket av Fusarium- og Microdochium-sopper medført mangel på norskprodusert såkorn av god kvalitet, spesielt i havre. Det er derfor behov for mer kunnskap om betydning og overlevelse ... -
Genetic variation in anther extrusion in oats and its relationship to Fusarium
(Master thesis, 2015-02-26)Anther extrusion (AE) is a trait that has been studied in wheat for its influence on Fusarium head blight. Fusarium is a disease causing great problems in Nordic small grain production, particularly in oat. However, AE ... -
Impact of additional blue light in the production of small plants of Abies laciocarpa and Picea abies propagated by seeds and seedlings
(Master thesis, 2016-04-01)The goal of this study was to examine how additional blue light affected growth and development of Picea abies and Abies laciocarpa seedlings and stem cuttings. The experiment was conducted at the Center for climate regulated ... -
Interactive effects of light quality and temperature on bud set and shoot elongation in Norway spruce (Picea ables) and Subalpine fir (Abies lasiocarpa).
(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 ... -
