The potential pre-anthesis and post-anthesis contributions of stem internodes to grain yield in crops of winter barley g d bonnett and l d incoll department of pure and applied biology , the university of leeds , leeds ls2 9jt, uk accepted: 30 september 1991 field experiments to assess the development. We investigated the relative importance of pre-anthesis assimilates stored in plant parts, mainly in the stem, and post-anthesis photosynthesis to drought resistance in wheat ( triticum aestivuml. Estimates of pre-anthesis assimilate contributions to grain carbon were obtained by weighting these partitioning coefficients by seasonal crop gross photosynthesis data (variant 1) and by crop dry-weight changes over the pre- and post-anthesis periods (variant 2) estimates of absolute contributions varied slightly between. Identifying avenues for increases in hi whilst maintaining post-anthesis photosynthetic capacity in wheat carolina rivera-amado, eliseo trujillo- negrellos, roger sylvester-bradley, gemma molero, matthew reynolds and john foulkes trigo (wheat) yield potential workshop 23rd and 24th march 2016 ceneb, ciudad. (pre-anthesis) cell division takes place at the base of the ovary wall and pericarp during anthesis and post-anthesis shape of the fruit is, especially in one variety, already clearly distinguishable in the pre- anthesis and is predominantly determined by cell division size of the fruit is determined by elongation during anthesis. Thus, it was estimated that pre-anthesis reserves contributed up to 74% to the grain yield of barley (hordeum vulgare l) (gallagher, biscoe & scott 1975) and 57% to the grain yield of wheat (gallagher et al 1976) when crops suffered from severe post-anthesis drought the contribution of pre-anthesis assimilate to grain.
However, it is still unclear if asymmetrical warming during vegetative periods can improve the post-anthesis physiological activities of winter wheat we have reported that winter night-warming promoted pre-anthesis plant growth and improved post-anthesis net photosynthetic rates, ultimately increasing grain yield (fan et. Thus, it was estimated that pre-anthesis reserves contributed up to 74% to the grain yield of barley (hordeum vulgare l) (gallagher, biscoe & scott 1975) and 57% to the grain yield of wheat (gallagher et al 1976) when crops suffered from severe post-anthesis drought the contribution of pre-anthesis assimilate to grain fill. (33) attempted to further elucidate the role of pre- and post-anthesis weather variables on fhb development using a large dataset collected from 15 states over a period of 27 years out of 380 weather-based predictors, representing temperature, rh, and rainfall summarized for different pre- and post-anthesis time win. Reserves of assimilate present in wheat and barley crops at flowering, and available for later translocation to the grains, could buffer grain yield against environmental stresses during grain filling this so-called pre-anthesis assimilate contribution to grain yield can be expressed as a percentage of yield (p1) archbold1.
In experiments with male‐sterile tomatoes, it was demonstrated that microsporogenesis was more sensitive to moderately elevated temperatures than megasporogenesis and post‐anthesis processes (peet et al, 1998) pre‐ anthesis high temperature treatments to brassica napus was also shown to reduce pollen fertility. Figure 5: 5 effects of pre- and post-anthesis water stress on recovery and subsequent grain production by rice plants (a) wild-type plants exhibit severe leaf senescence and yield loss due to water stress followed by rewatering ( compare well-watered control to water-stressed wild-type plants) transgenic plants expressing.
Understanding the nature of gene action of yield related traits under post- anthesis water stress will help to breed stress-resilient genotypes four bread fakthongphan j, graybosch ra, baenziger ps (2016) combining ability for tolerance to pre-harvest sprouting in common wheat (triticum aestivum l. Winter night warming promoted pre-anthesis plant growth and leaf development of winter wheat, which favored the grain yield • winter night warming improved post-anthesis photosynthetic capacity • post-anthesis photosynthetic capacity enhanced through increasing net photosynthesis rate and photochemical turnover. Ishs international symposium on growing media and soilless cultivation effect of pre and post anthesis foliar application of calcium on postharvest quality of gerbera cut flower. Anthesis is the period during which a flower is fully open and functional it may also refer to the onset of that period the onset of anthesis is spectacular in some species in banksia species, for example, anthesis involves the extension of the style far beyond the upper perianth parts anthesis of flowers is sequential within an.
The potential role of pre-anthesis high temperature acclimation in alleviating the negative effects of post-anthesis heat stress on stem stored carbohydrate remobilization and grain starch accumulation in wheat was investigated the treatments included no heat-stress (cc), heat stress at pre-anthesis only (hc), heat at. Contribution of pre-anthesis assimilation and remobilization to grain yield the behaviour of the four varieties was similar as they ranked in the same order for pre-anthesis and post-anthesis dry matter accumulation and grain yield and differences in soil characteristics induced similar changes in dry matter, n and p.
The putative gross maximum canopy photosynthesis was the highest for fraction of topdressed nitrogen of 30%, which was concomitant with the highest amount of post-anthesis accumulated assimilates the remobilization of pre-anthesis stored assimilates from vegetative organs into grains was hardly.

Changes in grain weight as a consequence of de-graining treatments at pre- and post-anthesis in synthetic hexaploid lines of wheat ( triticum durum x t tauschii ) daniel f calderini and matthew p reynolds australian journal of plant physiology 27(3) 183 - 191 published: 2000.
