Production of herbaceous perennials has been one of the most rapidly growing areas of floriculture for the last 8 to 10 years. However, greenhouse and nursery production of herbaceous perennials requires a significant effort to control the growth of some of these very vigorous plants. Until very recently the primary methods of control were scheduling and pruning. If a grower missed the target d...

In this study, a method using liquid chromatography triple quadrupole mass spectrometry (LC/MS/MS) is described for the analysis of the plant growth regulator chlormequat (CCC) in human urine. Analysis was carried out using selected reaction monitoring (SRM) in the positive ion mode. [(2)H(4)] labeled CCC as internal standard (IS) was used for quantification of CCC. The limit of detection (LOD)...

A field experiment was conducted during Rabi season, 2022 at crop research farm, Department of Agronomy Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj Uttar Pradesh India. The objective is to study the effect nitrogen plant growth regulators on yield economics wheat (Triticum aestivum L.). consists three levels Nitrogen (120, 140 160 kg/ha) [CCC – 0.2%, Tebuconazole...

Lodging risk in spring wheat has grown with the introduction of high-yielding cultivars that require high nitrogen (N) inputs to optimize grain yield and protein content. Canopy management (CM) strategies have been used reduce lodging risk. However, short growing season unpredictable moisture supply may limit use these Canadian Prairies. The objective this study was quantify ability agronomic p...

Pot marigold (Calendula officinalis L.) is a medicinal and ornamental plant. The effect of different concentrations of chlormequat (cycocel), and daminozide, two plant growth retardant, on plant height, flowering, the content of essence and some other traits in pot marigold (Calendula officinalis) was assessed. Plant growth retardants are commonly applied to limit stem elongation and produce a ...
