The potentiality of biostimulant (Lawsonia inermis L.) on some morpho-physiological, biochemical traits, productivity and grain quality of Triticum aestivum L.

Abstract

Background In conformity with the international trend to substitute the artificial agro-chemicals by natural products to improve growth and productivity of crops, there is a necessity to focus on the environment sustainable and eco-friendly resources to increase crops productivity per unit area. One of these resources is the use of biostimulants. The aim of this study is to allow the vertical expansion of wheat crop by improving its growth and productivity per unit area as well as enhancing its grain quality using henna leaf extract as a biostimulant. Results Field study was conducted to evaluate the potentiality of different doses of henna leaf extract (HLE) for improving the performance of wheat plants (Triticum aestivum L.) at three development stages. Results revealed that the response was dose dependent hence both 0.5 and 1.0 g/L doses significantly enhanced the growth of shoot and root systems, biochemical traits, yield and yield related components with being 1.0 g/L the most effective one. Furthermore, 1.0 g/L HLE markedly enhanced the quality of the yielded grains as revealed by increasing the content of soluble sugars (23%), starch (19%), gluten (50%), soluble proteins (37%), amylase activity (27%), total phenolics, flavonoids and tannins (67, 87 and 23%, respectively) as well as some elements including Ca (184%), Na and Fe (10%). Also, HPLC analysis of grains revealed that 1.0 g/L dose significantly increased the level of different phytohormones, soluble sugars and flavonoids (quercetin, resveratrol and catechin). Conclusion Application of Henna (Lawsonia inermis) leaf extract at 1.0 g/L dose as a combination of seed priming and foliar spray can be recommended as a nonpolluting, inexpensive promising biostimulant, it can effectively enhance wheat growth, biochemical traits and productivity as well as improving the quality of the yielded grains.

Initial Physiological, Biochemical and Elemental Garlic (Allium sativum L.) Clove Responses to T. vulgaris and S. aromaticum Extract Application

“…Coriander seed essential oil and extract decreased DPPH, ABTS antioxidant activity and total phenolic compounds in inoculated strawberry leaves, but only with lower applied concentrations [41]. A dose-dependent effect was observed with Lawsonia inermis L. extract, which increased wheat shoot and root system growth and accumulated 90% more total phenolic compounds in wheat compared to untreated plants [42]. The total concentration of polyphenols in potato leaves treated with extracts from Artemisia vulgaris L. increased by up to 20% compared to untreated plants and was dependent on the amount of the natural preparation used and the extraction method [43].…”

An Overview of Biostimulants’ Effects in Saline Soils

“…The Moringa leaf extract is also a rich source of growth regulators, e.g., zeatin, phenolics, ascorbate, and mineral nutrients [191,192]. The application of Henna Lawsonia inermis L. leaf extract at 1.0 g L −1 dose using a combination of seed priming and foliar spray can be recommended as a nonpolluting, inexpensive, promising biostimulant; it can effectively enhance wheat growth, biochemical traits, and productivity, as well as improve the quality of the yielded grains [193].…”
