Response of Syngonium Podophyllum Plant to Some Synthetic Cytokinin Types and Concentrations as a Foliar Application

Abstract

This investigation was executed to assess the effects of three synthetic cytokinins [6-benzylaminopurine (BAP), 6-(γ,γdimethylallylamino) purine (2iP) and furfurylamino-purine (kinetin)] at three concentrations for each type (100, 200 and 300 mg/l), beside the control one (tap water) on vegetative growth and some chemical analysis of Syngonium podophyllum plants. Two pot experiments were executed during the two successive seasons of 2019 and 2020 in a commercial farm in Belqas Khamis, Dakahlia Governorate, Egypt. The obtained results generally revealed that spraying of the three types and concentrations of synthetic cytokinins significantly enhanced plant height, number of leaves/plant, leaf area, foliage fresh and dry weight, root length, root fresh and dry weight compared to the control plants. Moreover, spraying of synthetic cytokinins was superior and significantly increased N%, P%, K%, total carbohydrates, total phenolics, chlorophylls and carotenoids content in leaves. Meanwhile, spraying of 2iP at 200 mg/l gave the highest values for most of the vegetative growth characters (plant height, leaves number and foliage fresh weight) and chemical composition (chlorophyll a, b, a+b, carotenoids, total carbohydrates and N, P and K contents in leaves) compared to other treatments. However, applying of kinetin at 200 mg/l gave higher values of foliage fresh and dry weight and chlorophyll a than other concentrations. Besides, spraying of BAP at 100 mg/l gave the highest roots fresh and dry weight. While spraying of BAP at 200 mg/l gave the highest value of total phenolics content compared to other treatments. Generally, the examined cytokinin types and concentrations could be arranged for their positive effects on Syngonium podophyllum descendingly as 2iP at 200 mg/l, BAP at 100 or 200 mg/l and kinetin at 200 mg/l.

Effective nutrient removal using nutrient film technique hydroponics unit under varying nitrate nitrogen concentrations

“…The outcomes are consistent with Dhanraj's findings from 2020, which showed that in vertical passive hydroponics, the maximum root length for the Arrowhead plant ( S. podophyllum ) was 33.32 cm (90 days) (Dhanraj, 2020). According to Kasem and Helaly (2021), chemical contents were applied as a foliar spray to arrowhead plants and it exhibits the highest Plant height (36.67 cm), leaves number (8), and highest root length (98.33 cm) among the several synthetic cytokinins that were employed to regulate the plants (Kasem & Helaly, 2021).…”
