“…The effectiveness increases on increasing the concentration in marigold (Kumar et al, 2010) and in chrysanthemum (Gautam et al, 2006). Salicylic acid @ 120 ppm imparts maximum plant height (50.63 cm) than its lower concentration in African marigold (Basit, 2018) and plant height increases on increasing concentration upto 500 ppm (Poudel & Subedi, 2020). Increased cell division both in stems and roots (Martin-Mex et al, 2005); rubisco chemical action and photosynthetic rate (Basit, 2018) due to salicylic acid may support the statement.…”

“…This paper reviewed the application of various biochemicals to quantify yield and quality of African marigold. Among phytohormones and plant growth regulators Gibberellins or Gibberellic acids (GA 3 ) (Sunitha, 2007;Pandey & Chandra, 2008;Ramdevputra et al, 2009;Rajhansa et al, 2013;Palei et al, 2016;Acharya et al, 2021;Karki et al, 2021), ethrel (Rajyalakshmi & Rajasekhar, 2014), paclobutrazol (Rathore et al, 2011), salicylic acid (Basit, 2018;Poudel & Subedi, 2020), Naphthalene Acetic Acid (NAA) (Kanwar & Khandelwal, 2013), Chlormequat Chloride (CCC) (Kumar et al, 2012;Rajyalakshmi & Rajasekhar, 2014), etc. are the most widely used and proven biochemical for ornamentals (including African marigold) with pronounced effect on plant growth, development, morphology, phenology and overall differentiation (Singh et al, 2019).…”

African marigold, being tall enough and producing large flowers suitable for preparing garlands, is the most cultivated cultivar of marigold in Nepal. Besides, pinching and other improved cultural techniques, a number of chemicals, hormones and phyto-hormones are being tested and found to impart a varying response in African marigold. This review has its importance for standardizing the type and concentration of plant growth regulators in African marigold. Online journals, scientific papers, proceedings, books, thesis and lecture notes are the key reference site for this review. Gibberellins or gibberellic acids (GA3), ethrel, paclobutrazol, salicylic acid, Indole 3 Acetic Acid, Naphthalene Acetic Acid (NAA), Chlormequat Chloride and sea weed extract are the most widely used and proven biochemical with pronounced effect on growth, development and differentiation in marigold. Among these, 300 ppm, 350 ppm and 450 ppm of GA3 results higher plant height, minimum days for flower initiation and higher basal diameter respectively. Similarly, 450 ppm for higher number of branches and leaves per plant and 400 ppm of GA3 or 600 ppm of CCC has been found to impart higher number and weight of flowers per plants. Besides, 1000 ppm of CCC has been found more effective to impart higher productivity (yield/ ha) in African marigold. Hence, plant growth regulators have been a valuable agent for optimizing yield and yield potential in African marigold.
