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.

Leaf nitrogen remobilisation for plant development and grain filling
Plant Biology, 2008AbstractA major challenge of modern agriculture is to reduce the excessive input of fertilisers and, at the same time, to improve grain quality without affecting yield. One way to achieve this goal is to improve plant nitrogen economy through manipulating nitrogen recycling, and especially nitrogen remobilisation, from senescing plant organs.

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 ...

Two Measures of Grain Filling in Spring Wheat
Crop Science, 1995Grain weight is a component of grain yield and duration of grain filling is a component of maturity. Both are important traits in applied plant breeding and both depend upon the grain filling process. Grain filling has been described by multi‐point and two‐point curves.

Inheritance of grain filling duration in spring wheat
Plant Breeding, 1999AbstractThe genetic basis of grain‐filling duration (GFD, days from anthesis to maturity) in six spring wheat hybrids involving nine varieties (‘Son‐alika’/‘Bobwhite’, ‘Sonalika’/‘Glennson 70’, ‘Lelija’/‘Bobwhite’, ‘Lelija’/‘Mitacore’, ‘Buckbuck’/‘Dugoklasa’, and ‘Vesna’/‘Raduśa’) and their F1, F2, BC1, and BC2 generations was studied in the field near

Grain filling and starch synthesis in barley
2000Barley is one of the oldest cultivated crops in the world. Although barley was later surpassed by rice, wheat, and maize as major human staples, important niches such as malt production nevertheless remain. Furthermore, barley has a wide physiological tolerance and is a major grain in marginal agricultural areas ranging from western Asia to near the ...

Earliness and duration of grain fill in winter wheat
Canadian Journal of Plant Science, 1992The duration of grain fill in wheat (Triticum aestivum L.) is one of the determinants of kernel weight. The purpose of this research was to investigate the genetic diversity for duration of grain fill in winter wheat. In one experiment the genetic diversity for duration of grain fill and the influence of temperature on heading, anthesis and duration ...

Copper stress affects grain filling in rice
Communications in Soil Science and Plant Analysis, 1999Abstract Rice (Oryza sattva L.) cv. Jaya was grown in refined sand at graded levels of copper (Cu) viz. 0.00065, 0.0065, 0.013, 0.065, 0.13, 0.65, and 6.5 mg L‐1. In acute Cu deficiency (0.0065, 0.00065 mg L‐1), the visible foliar symptoms appeared on young leaves as chlorosis changing to necrosis, later affected leaves appeared papery and withered ...

Starch synthesis and grain filling in wheat
2000Wheat is the most widely produced cereal in the world. The formation and characteristics of the grain are largely a function of starch biosynthesis. The starch is composed of granules with distinct class sizes, properties and patterns of occurrence within the spike.
