Genomewide Selection in Apple: Prediction and Postdiction in the University of Minnesota Apple Breeding Program
… predictive ability of genomewide selection for fruit traits by testing an additive prediction model, a model fitting heterozygote effects, and a model fitting fixed effects for major QTL. The second aim of this research was to assess the utility of genomewide selection for fruit traits in the …

Variation in growth, nutrition and phytochemicals of sequentially harvested shoots and fruits, and genetic studies of Lagenaria siceraria landraces in South Africa
… with edible plant parts such as leaves, shoots, fruit pulp, and seeds. However, studies on L. siceraria regarding the relationship between shoot, peduncle and fruit traits during growth; nutritional and phytochemical composition of sequentially harvested shoots and fruits; as well as genetic …

Primate-Plant Interactions in the Tropical Dry Forests of Northwestern Madagascar: Seed Dispersal and Sensory Ecology of Eulemur fulvus.
Fruiting plants and frugivores are involved in a complex set of interactions. Frugivores rely on fruiting plants as critical food resources, while fruiting plants rely on frugivores for seed dispersal services. Here, I measure the interrelatedness of brown lemurs (Eulemur fulvus) and the endemic …

Linking Spatial Patterns of Seed Dispersal and Plant Recruitment in a Neotropical Tree, Virola Calophylla (Myristicaceae)
… agents responded differently to some tree and fruit traits, indicating that dispersal agents can exert selection on traits affecting seed dispersal, but that the resulting selection pressures are likely to be inconsistent. To quantify landscape-scale seed dispersion, a mechanistic model was …

Studies in Blackberry: Development and Implementation of a Phenotyping Protocol for Blackberry Seedling Populations and Impact of Time of Day of Harvest on Red Drupelet Reversion for University of Arkansas Blackberry Genotypes
… standardized method of characterizing plant and fruit traits. A phenotyping protocol for blackberry was developed at UA and implemented for two years on UA seedling populations. The protocol included plant traits (health, vigor, estimated crop load, peak bloom date, and number of canes) and fruit …

Systematics and evolutionary ecology of Osteospermum section Polygalinae DC
… is characterised by remarkable variation in fruit structure and dispersal biology, putatively including species that employ myrmecochory (dispersal by ants). Myrmecochory is thought to be exceptionally prevalent in the species-rich Fynbos Biome and has gained interest as a possible driver of …

Nonrandom seed dispersal by lemur frugivores: mechanism, patterns and impacts
… National Park, Madagascar. An analysis of traits suggested that 84% of trees in Ranomafana are adapted for animal dispersal, of which more than 70% are dispersed by these three lemur species indicating their role as generalist dispersers. The distribution of fruit and seed size of …

Effects of systemic fungicides on floral attributes, pollination and fruit aroma in strawberries
… taste-relevant metabolites, thus impacting the fruit quality. However, there is a lack of studies which investigate these fungicide impacts, as existing studies often focus on individual impacts instead of considering the interrelationships between all associated factors.<br /><br /> This thesis …
