Seaweed extract and brassinolide can enhance the dwarfing characteristics of potted chrysanthemum
Main Article Content
Abstract
The search for environmental-friendly applications in agriculture is a priority and a necessity. The use of bio-stimulants such as seaweed extracts (SE) and brassinolide (BL) to improve plant growth, quality, and productivity is an effective and eco-friendly strategy. A pot experiment was carried out during the 2018 and 2019 seasons to investigate the effect of spraying plant growth retardants; cycocel (CCC) and paclobutrazol (PPP), in interaction with bio-stimulants; SE (Kelpak®) and BL (Milagrow®) on dwarfing characteristics of chrysanthemum [Dendranthema grandiflorum (Ramat.) Kitamura] cv. ‘Pink Zambla’ to achieve a desirable plant height with a high dwarfing value. Significant improvements of the studied traits; plant height, leaf number, branche number, plant biomass weight, flowering start, flower number, flower diameter, flowering period, and chlorophyll content was recorded for the combination treatments compared to the single application of the dwarfing factors. Concerning the key characteristics of chrysanthemum as potted plant, the best results were recorded in plants treated by combination of 3000 mg L-1 CCC or 50 mg L-1 PPP with different rates of Kelpak or Milagrow. It is possible to recommend the use of growth bio-stimulants along with growth inhibitors to produce a potted dwarf chrysanthemum plant with high flowering quality that increase its commercial value and meets consumer and market needs.
