Journal ArticleDOI
Gibberellins and Flowering of Grasses and Cereals: Prizing Open the Lid of the “Florigen” Black Box
Rod W. King,Lloyd T. Evans +1 more
TL;DR: A growing body of molecular evidence supporting these actions of GA may provide a future basis for manipulating flowering of grasses and cereals.
Journal ArticleDOI
Plant Growth Regulator Effects on Spring Cereal Root and Shoot Growth
Ari Rajala,Pirjo Peltonen-Sainio +1 more
TL;DR: Plant growth regulator applications have modest potential for modifying traits of spring cereal plant stand structure other than straw length and reduced main shoot growth in barley and wheat up to 20%.
Journal ArticleDOI
Controlling plant growth via the gibberellin biosynthesis system – I. Growth parameter alterations in apple seedlings
TL;DR: ‘York Imperial’ apple seedlings were continuously supplied via the roots with paclobutrazol, a triazole GA biosynthesis inhibitor, and plots of growth data indicate linearity of shoot longitudinal growth of GA3-treated seedlings.
Journal ArticleDOI
Decreased shoot stature and grain α-amylase activity following ectopic expression of a gibberellin 2-oxidase gene in transgenic wheat
Nigel E. J. Appleford,Mark Wilkinson,Qian Ma,Daniel J Evans,Marlon C. Stone,Stephen Pearce,Stephen J. Powers,Stephen G. Thomas,Huw Jones,Andrew L. Phillips,Peter Hedden,John R. Lenton +11 more
TL;DR: The marked decline in transcript abundance of both alpha-amylase gene families in aleurone was associated with a decreased content of bioactive GAs in grains of the semi-dwarf lines.
Journal ArticleDOI
Timing applications of growth regulators to alter spring cereal development at high latitudes
Ari Rajala,Pirjo Peltonen-Sainio +1 more
TL;DR: To study their potential in Northern growing conditions PGRs and their application time impacts on plant stand structure and yield formation in tall and short statured cultivars of barley, oat, and wheat, crops were studied in the field.

Journal ArticleDOI
Competition among wheat plants sown at a wide range of densities
DW Puckridge,CM Donald +1 more
TL;DR: An experiment was undertaken with wheat to study the effects of interplant competition on dry matter and grain production and it is suggested that the application of this type of analysis to the reaction of different genotypes to crowding may add to an understanding of crop performance.
Journal ArticleDOI
The relations between the main shoot and tillers in barley plants
E. J. M. Kirby,H. G. Jones +1 more
TL;DR: It is concluded that tillers, during their initiation and early growth, compete with the mainshoot for a limited supply of resources, thus reducing the size of the main shoot.
Journal ArticleDOI
Growth of Tiller Buds in Barley: Effects of Shade Treatment and Mineral Nutrition
G. M. Fletcher,J. E. Dale +1 more
Journal ArticleDOI
The effect of sowing date and plant density on barley
TL;DR: Proctor and Maris Puma barleys were sown in October, early March, and late April at low and high fertilizer levels, and nitrogen data indicated a loss of nitrogen from the plant at high densities.
Journal ArticleDOI
Effect of phosphorus applied as superphosphate on rate of development and spikelet number per ear of different cultivars of wheat
TL;DR: Phosphorus additions increased the spikelet number per ear, rate of spikelet initiation, and apex length significantly in all wheats, but had no effect on the duration of the vegetative phase, spikelet phase or elongation phase, or on leaf number.
