Abstract:

Efficient allocation of photoassimilates from source to sink tissues is important for optimal plant growth and yield as relative source and sink strength drives growth potential of plant organs. A common method aimed at improving plant yield has been to modify enzymes important to storage compound biosynthesis in sink tissues such as seeds. As the rate limiting step in starch biosynthesis, ADP-glucose pyrophosphorylase (AGPase) has received much attention in this regard. Previously, overexpression of AGPase in seeds resulted in an enhanced yield phenotype in which both plant yield and biomass

Abstract:

Proportional loss models commonly used in disease surveys are based on the assumption that per cent yield loss is the same in all crops, regardless of their yield potential. Estimates of regional crop loss may be inaccurate if the relationship between disease and yield loss is affected by crop yield potential. The importance of crop yield potential in disease: yield loss modelling was investigated and models for more accurate regional crop loss estimates were developed, taking crop yield potential into account. Two spring sown barley (cv. Triumph) experiments were conducted in 1987/88 and 198

At Maricopa, two and three insecticide applications were required for control of pink bollworm, Pectinophora gossypiella (Saunders), on WC-12NL and DPL-61, respectively. At Brawley, six and nine applications were required. Lint yield of WC-12NL was 30% higher than that of DPL-61 at Maricopa, while at Brawley, lint yields were about equal.

Genetic improvement of a number of crops including soybean (Glycine max L. [Merr]) has been associated with stay-green. Research on stay green genes has focused primarily on genes involved with photosynthesis and chlorophyll degradation.

The objective of this experiment was to determine the role of E-genes in the control of leaf senescence in soybean. The experiment was conducted in a split-plot design with three replications.

Abstract:

Leaves are responsible for the majority of the fixed carbon in most plant species. Along leaf development, the photosynthetic capacity increases until the organ reaches maturity. Consequently, at the onset of senescence the leaves have the highest photosynthetic activity, then, as the chloroplasts are dismantled and the photosynthetic machinery is degraded, leaves gradually lose the rate of carbon assimilation. Although the capacity to fix carbon declines as senescence progresses, nutrient remobilization from macromolecule degradation nourishes the developing sink organs. In this regard, delay

Abstract:

In general, yield reduction in most dryland maize growing areas of South Africa occur because seasonal rainfall distribution is erratic with annual variation that cannot be predicted accurately. Cultivar selection, planting date and plant density are other factors that consistently affect maize yield. Long growing season maize cultivars are higher yielding, particularly under conditions of good moisture and nutrient supply. However, as both moisture and nutrient availability becomes more limiting, yield tends to decline. Short growing season maize cultivars could yield more than long season co

Studies were conducted on three field trials of wheat cv. Kopara to investigate the lack of compensation by later determined components of yield because of early disease constraints.

The reduced root development and soil water deficits may reduce the ability of the plant to compensate for reductions in early determined components.

Abstract:

Increasing green leaf duration during grain filling in rice, using management practices to enhance plant nutrition and health, can increase grain yield. To test this hypothesis, two experiments were conducted in 2005/06. The first experiment with the objectives of evaluating the effects of nitrogen (N) and fungicide application at booting stage on 1) the green leaf area duration and grain yield and 2) on the evolution of the dry mass accumulation in grains. The treatments were three N rates (50, 100 and 150 kg ha-1) and management practices during the booting stage (supplementary application o

Abstract:

The influence of rootstock and canopy density on grape berry composition was investigated over the summer of 2003-2004 on a commercial vineyard at Waipara, North Canterbury. This experiment was designed to investigate the influence of rootstock and canopy density on the acid composition, potassium (K) content and final pH of harvested fruit (Pinot Noir AM 10/5 Lincoln Selection). The trial block consisted of eight rootstocks laid out to an 8 x 8 latin square, each plot consisting of five vines of the same rootstock. Two canopy treatments were overlaid the block (down whole rows, assigned rando

La croissance foliaire est une composante du rendement particulièrement importante chez les graminées fourragères, tant sur le plan de la quantité que sur le plan de la qualité de la biomasse produite. Nous avons donc étudié la croissance foliaire du point de vue de la mise en place des dimensions et des flux de carbone et d'azote, depuis le moment ou la feuille en croissance émerge des gaines des feuilles précédentes jusqu'à la fin de la croissance en longueur. La largeur et l'épaisseur moyenne de la feuille varient de manière importante entre la base et la pointe de la feuille. Elles sont gé
