Impacts of Humic Acid, Indole Butyric Acid (IBA) and Arbuscular Mycorrhizal Fungi (Glomus mosseae) as Growth Promoters on Yield and Phytochemical Characteristics of Hibiscus Sabdariffa (Roselle)

Abstract

Field experiments were carried out during the two successive summer seasons of 2015/2016 and 2016/2017. The experiments were accomplished in an open field located at Bader region, El-Beheira Governorate, Egypt to evaluate the effects of humic acid, indole butyric acid (IBA), and arbuscular mycorrhizal fungi (AMF) (Glomus mosseae) individually on vegetative growth, yield, and phytochemical characteristics of Hibiscus Sabdariffa (Roselle jamica). Experimental field plots were designed as randomized complete block design (RCBD). The obtained results of the two seasons, generally, showed that all treatments (HA, IBA, and AMF) individually enhanced the vegetative growth, yield of calyx, and phytochemical parameters of Roselle plants. The HA treatment was the most effective in enhancing most of the studied parameters and might be recommended for enhancing the vegetative growth, yield of calyx, and calyx phytochemical components of Roselle plants under the environmental conditions of Bader region, El-Beheira Governorate and other similar regions.

Rooting of Schinus terebinthifolia Raddi Cuttings as a Function of the Preparation Method and Indolebutyric Acid Concentrations

“…1-A1 and 1-A2). This increase may have been favored by the activity of the root system of plants with the increase of IBA concentration, since the use of IBA in the production of plants, increases rooting and favors the increase in the volume and length of the roots producing a system with a vigorous root, which allows an increase in the absorption of water and nutrients and, consequently, in the gain of leaf material and aerial part [22,23].…”

Hibiscus sabdariffa L. calyces’ and argon DBD plasma: potential eco-friendly cleaners for fire-damaged silver gelatin prints

“…It is a herb (family Malvaceae) commonly known as roselle, hibiscus and Karkade. This precious extract is cultivated in some tropical and subtropical areas (El-Kinany et al , 2020). It is available in Middle Eastern countries, China, Thailand, Mexico, etc.…”

“…Egyptian roselle contains higher quantities of anthocyanins and sugars (Pinela et al , 2019; Da-Costa-Rocha et al , 2014). The Hs plant is popular for its applications in food, medicine, cosmetics and pharmaceutical industries (El-Kinany et al , 2020; Naeem et al , 2019). The most important part of Hs is calyx, which has high antimicrobial activities (Salami and Afolayan, 2020).…”
