Are elevated rates of false recall and recognition in the Deese-Roediger-McDermott (DRM) paradigm associated with false autobiographical memories in everyday life? To investigate this issue, the authors recruited participants who reported improbable memories of past lives and compared their DRM performance with that of control participants who reported having lived only one life (i.e., their cu...
Veridical and false memories of children aged 6 to 15 years were studied in two experiments with the retrieval-induced forgetting paradigm. Using the Deese-Roediger-McDermott (DRM) false memory word lists, children's reports of true, but not false, memories showed evidence of retrieval-induced forgetting. These differences were observed across delays as long as 2 days following word list presen...
In this study we investigated the effect of maturity stage on chemical composition, in vitro dry matter digestibility (IVD) and volume of gas produced at 24 h (G24) of forages from Avena sativa L. (oats), Trifolium alexandrinum (berseem), Vicia sativa L. (vetch), Avena sativa-Vicia sativa (OV) and Avena sativaTrifolium alexandrinum (OB) mixtures collected at progressive morphological stages (S1...
Previous research had identified four serogroups of Rhizobium trifolii indigenous to the acidic Abiqua soil (fine, mixed, mesic Cumulic Ultic Haploxeroll). Nodulation of subterranean clover (Trifolium subterraneum L.) by two of the serogroups, 6 and 36, was differentially influenced by an application of CaCO(3) which raised the pH of the soil from 5.0 to 6.5. These studies were designed to char...
The production of secondary metabolites in Trifolium pratense L. suspension culture of the family of legume plants (Fabaceae) is low, and therefore there was an attempt to increase it by elicitation. New synthetic substance, 2-(2-fluoro-6-nitrobenzylsulfanyl)pyridine-4-carbothioamide, was tested as elicitor--a substance that showed the best elicitation effect after 48-hour application of 1 μmol...
Recent studies suggest that plant roots can avoid competition with other roots of the same plant, but the mechanism behind this behavior is yet largely unclear and their effects on plant performance hardly studied. We grew combinations of two ramets of Trifolium repens in a single pot that were either intact, disconnected for a shorter or longer time, or that belonged to different genotypes. In...
Kura clover (Trifolium ambiguum M.B.) is a persistent rhizomatous forage legume, whose use in the U.S.A. is limited by establishment difficulties in part attributable to nodulation problems. In this study, soil was collected from established stands of Kura clover growing in 9 diverse North American environments. Rhizobia were plant-trapped using Kura clover cv. Endura as host, then rhizobia fro...
Patterns of resource availability and heterogeneity shape the composition, productivity, and dynamics of plant assemblages in a wide variety of terrestrial ecosystems. Despite this, the responses of plant assemblages to simultaneous changes in the availability and heterogeneity of more than a single resource are virtually unknown. To fill this gap, microcosms consisting of assemblages formed by...
Low and high tunnels and root-zone heating systems are proven tools in horticultural production. However, impacts of their separate and combined application on crop yield, composition, and microclimates are underreported. We addressed these gaps in the literature by exposing lettuce (Lactuca sativa) to four microclimates established with low and high tunnels and root-zone heating during the spr...
Red clover (Trifolium pratense L.) is a globally significant forage legume in pastoral livestock farming systems. It is an attractive component of grassland farming, because of its high yield and protein content, nutritional value and ability to fix atmospheric nitrogen. Enhancing its role further in sustainable agriculture requires genetic improvement of persistency, disease resistance, and to...
