Effects of application in vivo of glyphosate, fluridone, and paclobutrazol to glasshouse-grown donor plants of Pennisetum purpureum Schum. on endogenous levels of abscisic acid (ABA) and indole-3-acetic acid (IAA) in young leaves and on somatic embryogenesis in cultured leaf explants were studied. Treatment of plants with glyphosate (100 milligrams per liter) resulted in elevated levels of endo...

Early cone formation is a consistent issue in Fraser fir Christmas tree plantations the eastern United States. Growers must remove cones by hand, resulting significant labor costs, as degrade aesthetic value of trees. In this study, we conducted two series experiments collaboration with several farms to determine effectiveness applying plant growth regulators (PGRs), specifically GA-inhibitors,...

Four bioagents i.e. yeast (Saccharomyces cerevisiae), Trichoderma viride, Bacillus subtilis, and Pseudomonas fluorescens in addition to humic acid, sulphated canola oil (sulphex 0.5%) and Paclobutrazol (PBZ) were applied to study their effect on disease incidence caused by Sclerotium rolfsii. Also, some vegetative parameters, tuber yield and enzymes activity of Jerusalem artichokes (Helianthus ...

abstract turf grass as a main grown cover plant has a unique place in green space planning. in order to study the effect of hydrogel and paclobutrazol on water requirement of turfgrasse (lolium perenne l. barbal) a factorial experiment based on a brcd with 3 replication was conducted in the summer of 2010 in mashhad. the factors under study were 4 levels of hydrogel (0, 3, 6, 9 gr/kg soil), 3 l...

Evaluation of Phenological Stages, Changes in GDD, and Grain Yield Wheat Cultivars Response to Planting Date Application Paclobutrazol

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...

The increase in potato production is constrained condition Indonesia grow the area with an altitude of 1500m above sea level. It known that at high temperatures gibberellin acid (GA) content plants will increase, thus inhibiting tuber formation. use growth retardants such as paclobutrazol can inhibit GA biosynthesis so it stimulate In this study, aim study was to determine effect concentration ...

Mentimun ( Cucumis sativus L.) merupakan keluarga Cucurbitaceae atau labu-labuan. Kebutuhan mentimun cenderung meningkat sejalan dengan pertambahan penduduk, peningkatan taraf hidup, dan kesadaran masyarakat mengenai pentingnya nilai gizi sehingga dibutuhkan teknologi budidaya tanaman yang dapat meningkatkan hasilnya. Penelitian ini bertujuan untuk menentukan interaksi antara komposisi media ta...
