BACKGROUND The gibberellins (GAs) GA5 (inhibitor of GA3 -oxidase), GA4 (biologically active), GA4/7 (commercially available mixture of Ga4 and GA7 ) prohexadione-calcium (ProCa, inhibitor of dioxygenases that render GAs bioactive, negative control),

The gibberellins (GAs) GAVegetative growth, berry weight, and sugar content were unaffected by treatments. ProCa did not affect the yield with respect to water control, although it reduced the levels of phenolics in berry skins, an undesirable effect

Premise of research. Plants growing under physical or leaf canopy shade often exhibit increases in shoot growth that allow for additional exposure to irradiance from sunlight. These shaded plants also usually exhibit an accelerated flowering, though

Stellaria longipes plant communities (ecotypes) occur in several environmentally distinct habitats along the eastern slopes of southern Alberta's Rocky Mountains. One ecotype occurs in a prairie habitat at ∼1000 m elevation where Stellaria plants g

Brassinosteroids (BRs) are a group of plant hormones and the bioactive BR, brassinolide (BL), is causally implicated in promoting cell elongation and cell proliferation. In Arabidopsis, the biosynthesis of BL is essential for hypocotyl etiolation in

Fertilisation of established perennial ryegrass forage pastures with nitrogen (N)-based fertilisers is currently the most common practice used on farms to increase pasture forage biomass yield. However, over-fertilisation can lead to undesired enviro

The growth and development of higher plants depends not only upon an active photosynthetic apparatus and adequate water and mineral nutrient supply, but also tight regulation of growth by plant hormones and specific secondary metabolites. Environment

BACKGROUND The effects of spraying gibberellic acid (GA3) at 20 or 30 g ha−1, with or without application of urea, on pasture dry matter (DM) yield, herbage nitrogen (N) concentration and feed quality were investigated in 2011 and 2012 for managed

There is increasing interest in the use of naturally occurring ‘biostimulators’ for enhancing the growth of agricultural and horticultural crops. Bacteria, fungi and protozoa, as well as marine algae-based seaweed extracts, can produce or contain

Gibberellins (GAs) are key modulators of plant growth and development. PsGA3ox1 (LE) encodes a GA 3β-hydroxylase that catalyzes the conversion of GA20 to biologically active GA1. To further clarify the role of GA3ox expression during pea (Pisum sati
