“…Nevertheless, to date, no studies have been conducted to study the effects of abiotic stress, and particularly water stress, on yield and nutrient accumulation in this crop. A few studies conducted on the subject regard dry matter partitioning (Hole et al, 1984;Benjamin and Sutherland, 1989) but in non-limiting growing conditions. Some works on sugar beet, a crop relative to red beet, showed that the environment strongly affects sugar beet growth, root yield and sugar quality (Tsialtas and Maslaris, 2006;Hoffmann et al, 2009;Tsialtas et al, 2010Tsialtas et al, , 2011.…”

A field experiment was carried out to analyse the growth of lettuce, onion and red beet in terms of : (a) canopy architecture, radiation interception and absorption ; (b) efficiency of conversion of absorbed radiation into biomass ; and (c) dry matter partitioning. Growth analysis, total solar radiation interception, PAR interception and absorption by the crop canopy, ground cover, maintenance respiration of onion bulbs and red beet storage roots were measured. Models for different leaf angle distribution and ground cover were used to simulate light transmission by the crop canopy.The three crops are shown to have contrasting growth patterns from both a morphological and a physiological point of view. Lettuce showed very high light interception and growth after the early growth stages but, throughout the growth cycle, this leafy crop showed the lowest radiation use efficiency due to the respirational cost of the high leaf area. Onion showed a lower early relative growth rate than lettuce and red beet. This was due partly to the low light interception per unit leaf area in the later stages of growth and partly to the low initial radiation use efficiency compared with the other two crops. On the other hand, thanks to more uniform distribution of the radiation inside the canopy, to the earlier termination of leaf development and to the very low level of bulb respiration, onion showed high radiation use efficiency and was able to produce a large amount of dry matter. Red beet leaf posture and canopy structure resulted in high light interception and absorption. Its radiation use efficiency was lower than that of onion, partly perhaps because of the more adverse distribution of the intercepted radiation fluxes within the canopy and partly because of the high respiration cost of a continuous dry-matter allocation to the leaves. However, this crop can accumulate a very large amount of dry matter as leaf blade development and storage root growth can both continue almost indefinitely, providing continuously available sinks.Ground cover gave a good estimate of the PAR interception only at low values of light interception but, in general, it underestimated PAR interception in all three crops. Ratios between attenuation coefficients established by considering PAR or total solar radiation and LAI or ground cover were calculated.# 1996 Annals of Botany Company

“…Growth patterns differ between isolated plants and those growing in dense populations, with isolated plants having a greater proportion of unopened umbels earlier in the growing season (Thompson and Price 1977). Wild parsnip plants in high density populations have lower total and umbel biomass (Thompson and Price 1977), and smaller basal stem diameters (Thompson 1978), but the ratio of shoot to root biomass is not significantly affected by plant density in crop plants (Hole et al 1984). Plants on the periphery of wild parsnip patches, under less densityrelated stress, are larger than plants found at the centre of the patch.…”

-J. 2010. The Biology of Canadian weeds. 144. Pastinaca sativa L. Can. J. Plant Sci. 90: 217Á240. The parsnip, Pastinaca sativa, was introduced to North America shortly after European settlement as an important root-crop. It subsequently escaped cultivation and naturalized as a less palatable ''wild'' form. Cultivation of parsnip has diminished in Canada to the point where it is now only a minor crop, but the wild form has increased as a troublesome weed, particularly in eastern regions.Wild parsnip is most prevalent in eastern Canada and the northeastern United States, but occurs across the continent except in the far north and extreme southeast. As a monocarpic biennial with a large tap root, it reproduces entirely by seed. A wide variety of habitats and soil types are tolerated. It is considered a noxious weed because of its toxic properties (primarily photo-activated dermatitis) to both humans and livestock. It invades disturbed sites, rights-of-way, pastures, perennial crops, and reduced-tillage fields where it effectively out-competes shorter vegetation.In arable fields, wild parsnip is normally controlled by tillage. Manual removal, cutting, and mowing can be effective in reducing seed production, but direct contact with plants or sap is hazardous. Various herbicides have been reported to be useful in the control of wild parsnip (e.g., glyphosate, 2,4-D, triclopyr, etc.), but little quantitative information is available on application rates and levels of control. Le panais, Pastinaca sativa, a e´te´introduit en Ame´rique du Nord peu apre`s la colonisation Europe´ene pour sa culture. C'e´tait un le´gume racine important. Par la suite, l'espe`ce s'est e´chappe´e pour donner une varie´te´« sauvage » moins comestible. Au Canada, la culture du panais a diminue´e pour n'eˆtre pre´sentement qu'une culture marginale. Toutefois la varie´te´sauvage s'est tellement re´pandue qu'elle est devenue une mauvaise herbe proble´matique, surtout dans les re´gions de l'Est. Le panais sauvage est surtout pre´valent dans l'est du Canada et le nord-est des É tats-Unis, mais on le retrouve un peu partout sur le continent, sauf dans les re´gions tre`s nordiques et celles le plus au sud-est. Cette bisannuelle monocarpique dote´e d'une grosse racine pivotante se multiplie uniquement par les semences. Elle tole`re de nombreux habitats et types de sol. On la conside`re comme une mauvaise herbe nuisible en raison de sa toxicite´(elle provoque essentiellement une dermatite active´e par la lumie`re) pour l'eˆtre humain et le be´tail. Le panais sauvage envahit les sites perturbe´s, emprises des chemins, les paˆturages, les champs de vivaces et champs ou le travail du sol est re´duit, en surpassant la ve´getation plus courte. Sur les terres arables, le labour permet de maıˆtriser son e´tablissement. Le sarclage manuel, la coupe et la tonte peuvent s'ave´rer efficaces pour re´duire la production de semences, mais il est risque´d'entrer en contact direct avec la plante ou sa se`ve. On rapporte que plusieurs herbicides permettent de lutter co...
