Genotypic variation in the grain photosynthetic contribution to grain filling in rice
Journal of Plant Physiology, 2020Grain filling in rice, a staple cereal crop worldwide, is a critical determinant of grain yield and quality. However, there is little available information on the relationship between grain filling and grain photosynthetic capacity in rice. This study evaluated the genetic diversity among six rice cultivars for their grain filling rate (GR0) and the ...

Physiology of Grain Filling in Barley
Nature, 1972THE relative importance of various photosynthetic organs as suppliers of assimilates to developing grain in barley and as determinants of the yield of grain per ear has attracted much attention. It has been shown that the major contributions are made by the flag leaves and photosynthetic tissues of the ears themselves1,2; little or no information is ...

GRAIN FILLING PERIOD AND GRAIN YIELD RELATIONSHIPS IN SPRING WHEAT
Canadian Journal of Plant Science, 1975Ten cultivars of spring wheat (Triticum aestivum L.) were compared on the basis of grain yield determined at intervals after anthesis. When the data on grain yield were transformed to a square root scale, regression methods showed that the growth curves of the grain weight could be adequately represented by low-order polynomial expressions of time ...

Drought Stress in Grain Legumes during Reproduction and Grain Filling
Journal of Agronomy and Crop Science, 2016AbstractWater scarcity is a major constraint limiting grain legume production particularly in the arid and semi‐arid tropics. Different climate models have predicted changes in rainfall distribution and frequent drought spells for the future. Although drought impedes the productivity of grain legumes at all growth stages, its occurrence during ...

Physiology of Grain Filling in Barley
Nature, 1974Walpole and Morgan1 have suggested that differences in absolute growth rates between grains at different spikelet nodes in barley result from differences in quantity of assimilate supplied by each subtending awn, and that this quantity varies in proportion to awn size.

Diallel analysis of grain filling rate and grain filling period in tropical maize (Zea mays L.)
Euphytica, 2018Grain yields of maize in the lowland tropics are generally limited by short days and high temperatures that minimize durations of incident light. Little has been published on the effects of this limiting environment on the genetics of grain filling rate (GFR), and grain filling period (GFP) in tropical maize germplasm.

Inheritance of Grain Filling Rate in Wheat
Cereal Research Communications, 1999Grain weight in wheat is the product of rate and duration of grain filling (GF). GF rate represents the rate of dry matter accumulation per grain during grain fill. The lack information regarding the genetic base of GF rate prompted this study to determine kind of inheritance, genetic components and heritability for the GF rate.

Starch accumulation in rice grains subjected to drought during grain filling stage
Plant Physiology and Biochemistry, 2019Drought stress during the grain filling stage severely affects the quality and quantity of starch in rice grains. The enzymes such as ADP-glucose pyrophosphorylase (AGPase, EC 2.7.7.27) and starch synthase (SS, EC 2.4.1.21) are the key regulatory enzymes involved in the starch biosynthesis. In this study, the activity of the AGPase and starch synthase (

Starch synthesis and grain filling in rice
2000The genetic resource of rice plant is so rich that many high yield and disease resistant cultivars adaptable to diversified agroenvironments have been bred, and currently it is the major staple food source for one half of world population. As in other cereals, the main constituent of rice grain is starch, thus the grain filling capacity is determined ...
