Predicting phenotypes based on genotypes and understanding the effects of complex multi-locus traits on plant performance requires a description of the underlying developmental processes, growth trajectories, and their genomic architecture. Using data from Brassica rapa genotypes grown in multiple density settings and seasons, we applied a hierarchical Bayesian Function-Valued Trait (FVT) appro...

background and objectives: early watergrass (echinochloa oryzoides) is considered as a new-introduced species and then as a potential invader. investigation of competitive traits of this species, in comparison with barnyardgrass (e. crus-galli), one of the most important weeds in rice fields of guilan province, would be useful to determine its spreading possibility as an aggressive weed. theref...

leaf wetness duration (lwd) is a key parameter in agricultural meteorology. because of difficulties involved in lwd being readily measured, several methods have been developed to estimate it from weather data. among the employed to estimate lwd, those that use physical principles of dew formation plus dew and/or rain evaporation have shown to be especially transmittable and of sufficiently accu...

Selected cultural and environmental variables were investigated for their influence on the efficacy of Phoma herbarum and Phoma exigua to cause disease on dandelion (Taraxacum officinale) under growth room conditions. In both species, mycelial fragments caused significantly greater disease severity on dandelion than spore suspensions. Mycelial age was not an important factor in disease severity...

The process of leaf elongation in grasses is characterized by the creation and transformation distinct cell zones. prevailing turgor pressure within these cells one key drivers for rate at which divide, expand differentiate, processes that are heavily impacted drought stress. In this article, a turgor-driven growth model grass presented, combines mechanistic from basis with ontogeny leaf. Droug...

We have compared the time course of leaf senescence in pea (Pisum sativum L. cv Messire) plants subjected to a mild water deficit to that of monocarpic senescence in leaves of three different ages in well-watered plants and to that of plants in which leaf senescence was delayed by flower excision. The mild water deficit (with photosynthesis rate maintained at appreciable levels) sped up senesce...

Songs in passerine birds are important for territory defense and mating. Speciation rates in oscine passerines are so high, due to cultural evolution, that this bird lineage makes up half of the extant bird species. Leaf warblers are a speciose Old-World passerine family of limited morphological differentiation, so that songs are even more important for species delimitation. We took 16 sonograp...
