Evaluation of Yield and Agronomic Performance of Leafed and Semi-leafless Pea Blends
Field pea has two distinct leaf morphologies: leafed (L) and semi-leafless (SL). The leafed pea is more susceptible to lodging, but it may have high yield potential when lodging is prevented. In contrast, the semi-leafless pea is bred for lodging resistance and has greater yield stability. However, …

Dietary Effects on the Stoichiometry of Growth, Regulation, and Wastes of Ozark Stream Insect Detritivores
… to examine effects of diet nutrient content and leaf litter type on growth, regulation, and wastes of aquatic invertebrate detritivores. I tested effects of leaf litter diet carbon:phosphorus (C:P) on growth and stoichiometric regulation of the detritivorous caddisfly Pycnopsyche lepida and used …

Canopy Architecture and Plant Density Effect in Short-Season Chickpea (Cicer arietinum L.)
… population density of varying chickpea canopy types, i.e., leaf type and growth habit, by investigating seed yield responses at 30 to 85 plants m-2 and ii) identify desirable parental traits for breeding programs by assessing growth and yield parameter responses to varying leaf types and growth …

Survival of Escherichia coli O157:H7 on cut and whole surfaces of spinach and leaf lettuce, packaged under modified atmospheric conditions
… of Escherichia coli O157:H7 have been linked to leafy greens in recent years. An overwhelming amount of lettuce and spinach on the market is sold in modified atmosphere packaging as ready to eat salad mixes. The objectives of this study were to determine the effects of modified atmosphere, …

The effect of field pea (Pisum sativum L.) basal branching on optimal plant density and crop competitiveness
… field pea is 88 plants m-2. As certain pea genotypes have the ability for increased branching, it may be possible for a producer to seed at a lower plant population without reduced yield or to choose a highly branched cultivar to have reduced risk of yield loss under conditions of poor …

Studies on fungal biomass and activity associated with the decomposition of plant litter in freshwater
… of hyphae on leaves which varied between leaf types and fungal species. Improvements were made to the agar film method by optimising extraction of hyphae from leaf litter and using a tetrazolium staining technique to detect metabolically active hyphae. An indirect method for estimating …

Physiological and genetic investigations of iron deficiency in field peas (Pisum sativum L.).
… between tolerant and sensitive field pea genotypes. Plants grown in NaHCO₃ developed symptoms indicative of Na toxicity and therefore KHCO₃ was selected for solution culture studies. On the basis of this result, 37 accessions were screened in solution culture containing 10 mM KHCO₃ and eight …

Producción y distribución de fotoasimilados en la vid (Vitis vinifera L.) durante el período de maduración : cambios en la respuesta fotosintética a la luz de las hojas por factores biológicos, ambientales y culturales
… Berry ripening depends on the available leaf area and the functionality of the leaves, it also depends on the microclimate where the leaves are working and the cluster are ripening, and finally on the translocations that are being headed towards to the cluster. Among other factors, …
