Determining to what degree seed weight differences are due to competition among seeds
for insufficient source is critical for the rational design of breeding and management …

The understanding of the changes produced by plant breeding on wheat grain yield and on
its determinants, through the study of the behaviour of cultivars released at different times …

In this major 1993 work, Lloyd Evans provides an integrated view of the domestication,
adaptation and improvement of crop plants, bringing together genetic diversity, plant …

Durum wheat (Triticum turgidum subsp. durum L.) is being increasingly grown in many areas
of the world, but there is a lack of information about the physiological processes limiting …

Studies manipulating the source-sink relationships during postanthesis in wheat have
shown inconsistent results, concluding that wheat yield could be either sink-or source …

There are some indications that wheat yields may be leveling off. It may be necessary to
analyze physiological processes to help identify opportunities for future breeding aimed at …

Grain number has long been considered to be a key determinant of yield in wheat crops and
cultivars. In this paper, we argue that both yield and grain number are constrained by a …

In cereal crops, environmental fluctuations affect different physiological processes during
various developmental phases associated with the formation of yield components. Because …

A simple model of phloem transport is presented, based upon Mūnch's original hypothesis of
convective bulk flow driven by an osmotically generated pressure gradient and saturatable …

Among the mineral nutrient elements, nitrogen (N) most often limits the growth and yield of
nonleguminous crop plants, which require relatively large quantities of N (from 1.5 to 5% of …
