Plant growth regulators: an alternative to frequent mowing
… thesis is to determine if the application of Plant Growth Regulators (PGR's) to frequently mowed semi-improved areas can minimize the total annual mowing costs at Naval Air Station Cecil Field, Florida and Naval Air Station Jacksonville, Florida. The highest potential savings are in areas …

Stereocontrolled synthesis of plant growth regulators Abscisic acid and Xanthoxin
… project is concerned with the total synthesis of plant growth regulators related to abscisic acid (ABA). The biological activity of these plant growth regulators, ABA and Xanthoxin, and their derivatives is influenced by the stereochemistry of the double bond system in the side chain, the …

Biochemistry and molecular biology of binding proteins for plant growth regulators.
Plant growth regulators have a vital role in plant growth and development. The cellular response to these regulators depends on the presence and the action of specific receptors. The plant growth regulators and their receptors act together in complexes which determine the final effects of the plant …

Use of Plant Growth Regulators to Increase Branching of Clematis Spp.
… a twining vine covered in showy blooms. Typical growth of hybrids is from the main leader, producing a thin, unbranched plant with one cyme. Apical dominance is released by cutting back the vine during production. Cutting back, or pinching, of a plant is labor intensive and compromises bloom for …

Using Plant Growth Regulators to Improve the Quality of Containerized Herbaceous Peony
… with application of gibberellic acid (GA3) and growth retardants, to produce marketable containerized peonies from a small crown in a single season (November to May). We evaluated chilling, GA3 and a growth retardant (uniconazole; UNZ) under controlled chilling and greenhouse forcing conditions. …

Influence of Plant Growth Regulators on Turfgrass Growth, Antioxidant Status, and Drought Tolerance
… status, drought and disease tolerance, and growth response to foliar application of soluble seaweed (Ascophyllum nodosum) extracts (SE) and humic acid (HA; 25% active HA or 2.9% active HA) in tall fescue (Festuca arundinacea Schreb), Kentucky bluegrass (Poa pratensis L.) and creeping …

Evaluation of plant growth regulators for managing fescue turf along highway rights-of-way
Plant growth regulators (PGR's) including metsulfuron plus mefluidide at 10 plus 140 g ha⁻¹, chlorsulfuron plus mefluidide at 20 plus 140 g ha⁻¹, imazethapyr plus imazapyr at 67.5 plus 2.5, 96.4 plus 3.6, and 115.7 plus 4.3 g ha⁻¹, ACP 2100 at 60, 120, and 180 g ha⁻¹, and DPX L5300 plus mefluidide …

Plant growth regulators and biostimulants for use in varying management systems to improve corn grain yield
Plant growth regulators (PGRs) and biostimulants are product chemistries that have recently become popular in the agricultural market. There is no concrete evidence however, for their best place in a management system to optimize their return on investment and crop yield potential. The objective of …

Effects of commercial kelp extract and plant growth regulators on growth of Gracilaria gracilis in culture
… commercial seaweed extract (Kelpak®) to crop plants has proven to be beneficial as it improves growth and yields. Its efficiency has been attributed to its production method that involves a cold process, resulting in a product containing significant amounts of plant growth regulators (auxins …

The Use of Plant Growth Regulators to Improve the Traffic Tolerance and Repair of Overseeded Bermudagrass
… of synthetic cytokinins or cytokinin-enhancing plant growth regulators (PGRs), such as trinexapac-ethyl, may improve the traffic tolerance of "Patriot" and "Tifsport" hybrid berudagrasses (Cynodon dactylon var. dactylon x Cynodon transvaalensis). This study was designed to mimic the agronomic …

Responses of two grass species to plant growth regulators, fertilizer N, chelated Fe, salinity and water stress
A series of studies were initiated to investigate growth responses of Kentucky bluegrass (Poa praetensis L.) and creeping bentgrass (Agrostis palustris Huds.) to foliar applications of two plant growth regulators (PGR) and/or chelated Fe (Na Fe diethylene triamine pentaacetate). Environmental …

The effects of photoperiod, pinching, and plant growth regulators on growth and flowering of Abutilon x hybridum
… well-branched, and uniform-flowering pot plant. The objective of this research project was to form a foundation on which a commercial growing program could be developed. Growing flowering maple under short-day conditions (SD) significantly reduced plant height. Plants grown under SD were …

Influence of plant growth regulators on turfgrass polar lipid composition, tolerance to drought and salinity stresses, and nutrient efficiency
Two groups of plant growth regulators (PGRs), seaweed extract and triazole chemical, have been used in turfgrass management for improving turf quality and strengthening turfgrass tolerance to environmental stress. In order to understand the physiological functions and stress-tolerance mechanisms of …

Influence of seaweed extract and other plant growth regulators on growth, persistence, and quality of tall fescue and their potential to alleviate tall fescue toxicity to livestock
… the influence of seaweed extract and other plant growth regulators on forage quality and persistence of endophyte-infected (Acremonium coenophialum Morgan-Jones and Garns) and endophyte-free tall fescue (Festuca arundinacea Schreb.). The influence of plant growth regulators on forage quality …
