Fenugreek Seed Extract Enhanced the Growth of Vicia faba and Zea mays Seedlings

Abstract

H IGHER plants produce many phytochemical constituents that not only play a pivotal role in plants producing them, but also affect their neighboring plant communities. This study was conducted to evaluate the effect of fenugreek seed extract on the growth of faba bean (Vicia faba) and maize (Zea mays) seedlings. The allelochemical components of fenugreek seed extract were analysed and confirmed the abundance of vanillic, syringic, 4-hydroxycinnamic, sinapic, caffeic, salicylic and p-hydroxybenzoic, ferulic acids as well as coumarin. Fenugreek seed extract up to 1.0 % (w/v) efficiently enhanced the growth as well as the chlorophyll content of faba bean and maize seedlings. Furthermore, elevated levels of the amylolytic and proteolytic activities under these concentrations of fenugreek treatments were associated with a marked accumulation of soluble sugars and proteins. Moreover, the potentiality of fenugreek treatments to accumulate phenolic and flavonoid was associated with stimulation in the activities of phenylalanine ammonia lyase, peroxidase and polyphenol oxidase as well as a marked enhancement in total antioxidant capacity which would improve the plant antioxidant status. Concerning the membrane integrity, fenugreek treatments caused a pronounced retardation in both MDA and H 2 O 2 content. Our results elucidated the effect of fenugreek seed extract on the growth and some physiological behaviors of both faba bean and maize seedlings.

CO2 Enrichment Differentially Upregulated Sugar, Proline, and Polyamine Metabolism in Young and Old Leaves of Wheat and Sorghum to Mitigate Indium Oxide Nanoparticles Toxicity

“…After elution with ddH 2 O, glucose, fructose, sucrose, and raffinose concentrations were measured (HPAEC-PAD) ( Vergauwen et al, 2000 ). Non-heated supernatant was used for measuring the activity of the key sugar enzymes ( Madany and Khalil, 2017 ). The activity of the invertase enzymes was measured In TAE buffer with 100 mM sucrose.…”

“…The reaction mixture containing citrate and glycogen initiated the starch synthase ( Nishi et al, 2001 ). A 0.2%v starch solution containing 0.05% of I2/KI (w/v) in 0.05% HCl was used to detect amylase activity at 620 nm ( Madany and Khalil, 2017 ).…”

Cropping Systems of Fenugreek with Faba Bean to Reduce Broomrape Infestation

“…No doubt, increasing fenugreek plant density from 50 to 100% of sole cropping increased total phenols concentration in faba bean rhizosphere. It is important to mention that higher plants produce many phytochemical constituents that not only play a pivotal role in plants producing them but also affect their neighboring plant communities (Madany and Khalil, 2017). Also, they reported that the allelochemical components of fenugreek seed extract were nine phenolic compounds.…”

“…This biological situation will maintain leaf chlorophyll pigment from deterioration. It is known that the total leaf area of faba bean seedlings was significantly increased by increasing fenugreek extract concentration (Madany and Khalil, 2017), meanwhile, high densities of faba bean plants can cause the plants to senesce earlier (Gezahegn, 2019). Cropping Systems of Fenugreek with Faba Bean to Reduce Broomrape Infestation  The interaction between ridge widths and cropping systems Number of spikes per m 2 and their dry weight per m 2 and leaf chlorophyll b were significantly affected by the interaction between ridge widths and cropping systems in both seasons (Table 2).…”

Fertilizing Potentiality of Fungal-Treated Olive Mill Solid Waste to Improve Some Growth and Physiological Parameters of Vicia faba L.

“…Some plant extracts or residues may inhibit germination, emergence and subsequent growth of other plants by exuding toxic substances. These substances are called allelochemicals (Madany & Khalil, 2017;Hassanein et al, 2019). When these allelochemicals are taken up by germinating seeds of the same or of other plant species, there may be some degrees of germination and emergence inhibition or growth injury (Hassanpouraghdam et al, 2010).…”
