Plant genotype and induced responses affect resistance to herbivores on evening primrose (Oenothera biennis)
1. Although both genotype and induced responses affect a plant’s resistance to herbivores, little is known about their relative and interactive effects. This study examined how plant genotype of a native plant (Oenothera biennis) and induced plant responses to herbivory affect resistance to, and interactions among, several herbivores. 2. In a field experiment, genetic and environmental variatio...
متن کاملCovariation and composition of arthropod species across plant genotypes of evening primrose, Oenothera biennis
Genetic variation in plants has broad implications for both the ecology and evolution of species interactions. We addressed how a diverse community of arthropod species covary in abundance among plant genotypes of a native herbaceous plant (Oenothera biennis ), and if these effects scale-up to shape the composition, diversity, and total abundance of arthropods over the entire lifetime of plants...
متن کاملGenotype-by-environment interactions leads to variable selection on life-history strategy in Common Evening Primrose (Oenothera biennis).
Monocarpic plant species, where reproduction is fatal, frequently exhibit variation in the length of their prereproductive period prior to flowering. If this life-history variation in flowering strategy has a genetic basis, genotype-by-environment interactions (G x E) may maintain phenotypic diversity in flowering strategy. The native monocarpic plant Common Evening Primrose (Oenothera biennis ...
متن کاملSomatic Embryogenesis and Plant Regeneration in Evening Primrose (Oenothera biennis L.)
Callus induction responses and regeneration through callus-mediated SE were studied from evening primrose (Oenothera biennis L.) as an important medicinal plant of Onagraceae mainly known for its gamma-linoleic acid (GLA) content. The effects of cytokinins, 6-Benzylaminopurine (BAP) and N-(2-furfurylamino)1-H-purine-6-amine [Kinetin (Kin)] and their concentrations (0, 0.5, 1.0 and 1.5 mg/l) in ...
متن کاملA Study on Evening-Primrose (Oenothera biennis L.) Callus Regeneration and Somatic Embryogenesis
Evening primrose (Oenothera biennis L.) is a wild flower with high and valuable oil content. High seedshattering, indeterminate inflorescence and heterogeneous germination limit the commercial cultivation ofthis plant. Besides agronomical research, breeding programs can also remedy the above mentioned problems.Since traditional breeding methods take a long time, using techniqu...
