Description: Three experiments were conducted to investigate the effect of paclobutrazol on shoot and cambial growth of nine tree species located in Indiana and Louisiana, U.S. In Experiment I, white oak (Quercus alba L.) and red oak (Q. rubra L.) in Indiana were treated in April 1995 with paclobutrazol using the soil drench method. In Experiment II, paclobutrazol was applied in April 1996, usi...

Product % Label Rate Active ingredient Paclobutrazol ounces/1,000 sq.ft . Paclobutrazol/Acre Andersons TGR (Turf Growth Regulator) and Turf Enhancer formulations are effective tools for reducing existing Poa annua in turf Paclobutrazol, the active ingredient in TGR and Turf Enhancer, is a root-absorbed gibberillic acid inhibitor. Since paclobutrazol is a growth regulator, you will see a differe...

Despite the increasing rate of nanoparticles (NPS) production and their application in agriculture, few studies have focused on their effect on plant growth. So, the present research was conducted in laboratory and greenhouse conditions. First, superparamagnetic iron oxide nanoparticles (SPIONS) with a humic acid coating (Fe3O4/HA) were synthesized in laboratory...

Abstract This study was carried out in the laboratory of Shangqiu Institute Technology, Henan to investigate effect a different combination inorganic salt on quality and physiological characteristics cut flowers (CFs) Perpetual Carnation. Furthermore, find best preservation solution that can enhance ornamental value CFs Carnation prolong its vase life. Sucrose, 8-hydroxyquinoline, paclobutrazol...

Amorphophallus campanulatus (Elephant Foot Yam) is a rich source of starch, essential amino acids and therefore, used as a vegetable. It is cultivated and utilized in various regions of South India. Triazole compounds are widely used systemic fungicides to control diseases in plants and animals. Many of the triazole compounds have both fungi toxic and plant growth regulating properties. Hence, ...

In order to evaluate the effect of plant growth regulators on sex determination and yield, an experiment was conducted by spraying different hormonal combinations on medicinal pumpkin. Experimental treatments were included different concentrations of NAA (25, 75, 100, 125 mg/l), paclobutrazol (50, 100, 200 and 300 mg/l) and combination of growth regulators (NAA 25 mg/l + PBZ 50 mg/l), (NAA 75 m...

Shoot extension of Rhododendron ‘Sir Robert Peel’ was reduced, but flowering was more precocious after treatment of plants with paclobutrazol. All of the drench rates tested (0.05 to 0.4 g a.i./pot) proved excessive and resulted in prolonged shoot growth reduction but greatly increased the number of flowers. However, flowers produced at the higher drench rates were grossly malformed and unaccep...

Fruit-set in tomato (Solanum lycopersicum) depends on gibberellins and auxins (GAs). Here, we show, using the cv MicroTom, that application of N-1-naphthylphthalamic acid (NPA; an inhibitor of auxin transport) to unpollinated ovaries induced parthenocarpic fruit-set, associated with an increase of indole-3-acetic acid (IAA) content, and that this effect was negated by paclobutrazol (an inhibito...

David P. Horvath USDA–Agricultural Research Service, Plant Science Research, 1605 Albrecht Boulevard, Fargo, ND 58105-5674 Signals from both leaves and apical or axillary meristems of leafy spurge are known to inhibit root bud growth. To test the hypothesis that carbohydrates and growth regulators affect root bud growth, decapitated leafy spurge plants were hydroponically treated with glucose, ...
