چکیده
Foliar sprays of growth regulators have commercial potential for improving the performance some parameters associated with alternate bearing in pecan trees. The objective was to evaluate behaviour through analysis seasonal variations buds and leaflets non-structural carbohydrates (glucose, fructose, sucrose, starch), mineral nutrients (N-total, P, K+, Ca2+, Mg2+, Fe2+, Cu2+, Mn2+ Zn2+), yield components (nut weight per kilogram kernel percentage) oxidative metabolism (superoxide dismutase, hydrogen peroxide, catalase, guaiacol peroxidase antioxidant capacity) cv. Wichita trees response foliar applications gibberellic acid (50 mg L?1), calcium prohexadione (500 L?1) or thidiazuron (10 L?1). experiment a completely randomized experimental design five replicates. regulator (GRs) help maintain concentration between evaluation years. With exception K+ (12.9 10.9 g kg?1) Zn2+ (45.1 30.5 kg?1), GRs did not show any effects on concentrations nutrients. results suggest improve bearing, including metabolism.

Sunflower morphology and yield as affected by foliar applications of plant growth regulators
Plant height of sunflower is a major agronomic trait affecting crop performance in the field and its adaptation to mechanical harvest. Field experiments were conducted to study the effect of foliar application of paclobutrazol (PBZ) at 12.5 g ai/ha, mepiquat chloride (MPC) at 25.0 g ai/ha and chlormequat chloride (CCC) at 1,500 g ai/ha in single or double applications on sunflower plant mor...
متن کامل16 The Response of Foliar Carbohydrates to Elevated [ CO 2 ]
Accumulation of foliar carbohydrates is one of the most pronounced and universal changes observed in the leaves of C3 plants grown at elevated CO2 concentration (e[CO2]). Carbohydrates are both the product of photosynthetic cells and the substrate for sink metabolism. However, carbohydrates are not just substrates; and the role of carbohydrates in regulation of the expression of many plant gene...

Changes of phenolic compounds and non-structural carbohydrates on alternate bearing cycle in ‘Kinnow’ mandarin trees
In this study we have demonstrated the variations of carbohydrates and phenolic compounds present in the leaves and stems of ‘Kinnow’ mandarin (Citrus reticulata Blanco) trees in alternate bearing cycle and the possible involvement of these compounds to flower bud formation process. The amounts of these compounds were determined in the leaves and stems of “on” and “off” trees monthly from Nov...
