Plant mineral accumulation, use and transport during the life cycle of plants: A review

Abstract

Liptay, A. and Arevalo, A. E. 2000. Plant mineral accumulation, use and transport during the life cycle of plants: A review. Can. J. Plant Sci. 80: [29][30][31][32][33][34][35][36][37][38]. Minerals accumulated during each stage of plant development are important, especially for the initial portion of subsequent stages of growth. For example, minerals acquired during seed ontogeny are largely responsible for the earliest stage of seedling growth. Without these minerals, seedling development would be arrested or impossible. Thus, even though the amount of minerals may be relatively small in the seed, their presence is absolutely essential. Similarly, although the mineral nutrient content of a seedling used as a transplant in establishing a crop in the field may seem rather minuscule, the importance to the initiation of development of the successive stage of growth is critical. Moreover, seedling-mineral content, plant performance and seed production can be improved by the selection of optimal cultural practices. This review examines acquisition, content and use of minerals in the various stages of plant development and growth as well as agricultural approaches to enhance mineral accumulation.Key words: Nutrient uptake, field crop establishment, seed mineral content, seed yield, crop growth.Liptay, A. et Arevalo, A. E. 2000. Accumulation, utilisation et transport des minéraux durant le cycle biologique des plantes. Mise au point bibliographique. Can. J. Plant Sci. 80: 29-38. Les minéraux absorbés à chaque stade de croissance de la plante sont importants, en particulier pour la portion initiale de chaque stade ultérieur. Ainsi par exemple, les minéraux absorbés durant l'ontogénie de la graine joueront un rôle déterminant dans les premiers de la croissance de la plantule. Sans eux, celles-ci seraient entravées ou impossibles. Donc même si les quantités absorbées dans la graine sont dans certains cas relativement petites, leur importance n'en demeure pas moins essentielle. De même, si la teneur en éléments nutritifs minéraux dans le jeune plant destiné à être repiqué au champ peut paraître infime, leur présence jouera un rôle critique dans l'initiation de chacun des stades de croissance successifs. D'autre part, il est possible, en adoptant les pratiques culturales optimales d'améliorer la teneur en minéraux du jeune plant et avec elle les performances de la plante et sa production semencière. La revue bibliographique porte sur l'acquisition, les concentrations et l'utilisation des minéraux aux divers stades de croissance et de différenciation, de même que sur les moyens agronomiques de stimuler cette accumulation. Mots clés:Absorption des éléments nutritifs, installation en pleine terre, teneur minérale de la graine, rendement semencier, croissance végétaleCrop production and seedling performance in the field are the result of an adequate supply, distribution and accumulation of minerals, especially during seed formation. For example, minerals are collected at each stage of plant development in preparation for futu...

Plant growth habit, root architecture traits and tolerance to low soil phosphorus in an Andean bean population

“…Selection of genotypes with greater seed P content may improve plant growth in low P soils. Nutrients stored in the seed are important for germination and early plant growth (Liptay and Arevalo 2000). Increased seed P content partially compensated for the negative eVects of low P soils on early seedling growth in wheat (Triticum aestivum L.), by increases in shoot dry weight, leaf size, and root length (DeMarco 1990).…”

Nutrient stoichiometry in winter wheat: Element concentration pattern reflects developmental stage and weather

“…The whole life cycle of the crop, i.e., “from seed to seed” is rarely investigated. Nutrient requirements, nutrient uptake rates and element stoichiometry vary across the life cycle of plants including agricultural crops 4 7 8 9 10 . Element stoichiometry in plants is affected partly by soil element availability in combination with uptake capacity of the plant independent of its growth rate, and partly by the element uptake of the plant largely driven by its growth rate 1 11 .…”

Assessment of the Dynamic Phosphate Model PHOSMOD using Data from Field Trials with Starter Fertilizer to Cereals

“…In cereals, however, most of the P is taken up during the vegetative period (Batten 1992), even though there may be a requirement for some external supply of P also after anthesis (Grant et al 2001). During the grain filling period, energy is mostly used for relocation of nutrients from the vegetative organs to the grain (Liptay and Arevalo 2000). At the hard dough stage (GS 87), kernels reach physiological maturity and accumulation of starch and other nutrients ceases.…”
