Steryl glycoside is synthesized from mevalonate [2- ¹⁴C] in both maturing pea seeds and etiolated pea seedlings. The maturing seed appeared more active than the seedlings for this synthesis. The sugar moiety was identified predominantly as glucose by acid hydrolysis and paper chromatography of the aqueous extract of the hydrolysate....
High protein wheat seeds frequently perform better than low
protein seeds of the same variety. Protein content of seeds can be
increased by management practices, the most important of which is
rate and timing of N applications. The purpose of this study was to
determine the chemical, biochemical and physiological...
Field experiments were established in 1982 and 1983 on a Woodburn silt loam soil (Aquultic Argixeroll) to examine the effect of S fertilizer on dinitrogen fixation and dry matter yield of 10 week-old seedling alfalfa (Medicago sativa L. cv. 'Apollo'). Six levels of S fertilizer (0 to 67.2 kg S/ha)...
During barley germination, α-amylase and other hydrolases are synthesized in the aleurone layer and secreted into the starchy endosperm. As starch is degraded by amylases, lysophospholipids are released from inclusion complexes with the starch and undergo hydrolysis by a lysophospholipase (LPL) activity. Studies with embryo-free half seeds and isolated aleurone...
Under defined cultural conditions, large populations of zygotes
of the brown algae Fucus vesiculosus L. and F. distichus L. Powell
synchronously form a cell wall shortly after fertilization. Intact cell
walls, free of cytoplasm and maintaining shape properties of early
stages of embryo development, have been isolated from these zygotes....
