Changes in growth, hormones levels and essential oil content of Ammi visnaga L. plants treated with some bioregulators

Abstract

The effects of foliar application of different concentrations of amino acids (tyrosine and phenylalanine) and phenolic acids (trans-cinnamic acid, benzoic acid and salicylic acid) on growth, pigment content, hormones levels and essential oil content of Ammi visnaga L were carried out during two successive seasons. It is clear that foliar application of either amino acids or phenolics significantly promoted the growth parameters in terms of shoot height, fresh and dry biomass, number of branches and number of umbels per plant. The increment of growth parameter was associated with elevated levels of growth promoters (IAA, GA3, total cytokinins) and low level of ABA. The greatest increase in the previously mentioned parameters was measured in plants exposed to different concentrations of phenols particularly in benzoic acid-treated plants. Such effect was concentration dependent. All treatments led to significant increments in yield seeds and oil content. Moreover, gas liquid chromatographic analysis revealed that the main identified components of essential oil were 2,2-dimethyl butanoic acid, isobutyl isobutyrate, α-isophorone, thymol, fenchyl acetate and linalool. Phenolics and amino acid treatments resulted in qualitative differences in these components of essential oil.

Influence of foliar spray with phenylalanine and nickel on growth, yield quality and chemical composition of genoveser basil plant

“…These results are in harmony with those obtained by Moursy et al (1988) on Datura stramonium, Refaat and Naguib (1998) on peppermint (Mentha piperita), Habba (2003) on Datura innoxia, Balbaa and Talaat (2007) on rosemary plants and Talaat et al (2013) on ammi visnaga. Also, the results corroborate with the findings of Gamal et al (1997) on Cymbopgon citrates herb who reported Phe caused an enhancement in plant growth during vegetative and flowering stages.…”

Composition chimique d’Ammi visnaga L. (Lam.) marocaine et activité antibactérienne de son huile essentielle vis-à-vis de bactéries productrices et non productrices de beta-lactamases à spectre élargi

“…L'HE de l'A. visnaga de Giza en Egypte tout comme celle de Constantine en Algérie ont été identifiées comme contenant de l'acide 2,2-diméthylbutyrique à 28.9% et 30.1% ainsi que du thymol à 13.2% et 6% respectivement [18,23]. En Turquie cette HE est plutôt dominée par le nérol (29.98%) et le bisabolol (20.86%) [34].…”

“…Elle est douée d'activité antispasmodique et est pré-conisée lors de crampes d'estomac, de calculs rénaux, de coliques néphrétiques et de douleurs au niveau du tractus urinaire [3][4][5]7,8]. Elle sert également de remède contre l'asthme, l'angine de poitrine, les maladies cardiovasculaire, le diabète et le vitiligo [3,[9][10][11][12][13][14][15][16][17][18].…”

“…Moins étudiée, son huile essentielle généralement composée de molécules de type esters et monoterpènes oxygénés tels que le linalol, le thymol [18][19][20][21][22] est dotée d'activités antibactérienne, antifongique et insecticide [20,21,23,24].…”

“…The results suggest that the application of citric acid in higher concentration promotes the accumulation of dry matter in the sprouts, possibly through the participation in the synthesis of growth hormones that control and coordinate cell division (Amin et al, 2016). Similarly, AB at concentrations of 5-20 mg L -1 stimulates growth and elevates levels of growth promoters in Ammi visnaga L. (Talaat et al, 2014). In addition, the AB increases the dry matter content and yield in soybean plants at concentrations of 100 to 400 mg L -1 (Anjum et al, 2013).…”
