The effectiveness of spraying foliage with urea to provide nitrogen (N) to augment the
seasonal internal cycling of N in young nectarine trees (Prunus persica (L.) Batsch var …

Leaf senescence is characterized by nitrogen remobilization to developing seeds of annual
plants, or surviving organs of perennial species. It has been demonstrated that high …

Leaf senescence, which is the last developmental phase of plant growth, is controlled by
multiple genetic and environmental factors. Leaf yellowing is a visual indicator of …

The translocation of nitrogen was studied in vegetative wheat plants (Triticum aestivum L. cv.
SUN 9E) grown with a limited supply of nitrogen. The concentration of nitrogen in xylem sap …

Research into extreme drought tolerance in resurrection plants using species such as
Craterostigma plantagineum, C. wilmsii, Xerophyta humilis, Tortula ruralis, and Sporobolus …

Carbohydrate accumulation and utilization during shoot regrowth after defoliation and winter
has been studied extensively in most species used as forage. However, recent work …

Leaf senescence and associated changes in redox components were monitored in
commercial pea (Pisum sativum L. cv. Phoenix) plants grown under different nitrogen …

A substantial percentage of the grain nitrogen (N) in cereal crops originates from the
remobilization of N stored in vegetative tissues before anthesis. In wheat (Triticum aestivum …

The assimilation of inorganic N, in the form of ammonia, onto C skeletons for the production
of amino acids is one of the most important biochemical processes in plants. In an actively …

The functions of mitochondria during leaf senescence, a type of programmed cell death
aimed at the massive retrieval of nutrients from the senescing organ to the rest of the plant …
