Abstract
The phenomenon of allelopathy has been known for more than 2000 years. This phenomenon consists of the chemical interference of plant species (or other organisms), by enhancing, or inhibiting, the germination, seedling growth, or development of other plant species (or other organisms). This paper aimed to investigate the allelopathic potential of the aqueous extract of different parts of Matricaria chamomilla L. on germination parameters (radicle, coleoptile length, and dry weight) of two Moroccan varieties of durum wheat. Chamomile extracts from leaves, roots, or flowers at concentrations of 50 and 100 g·L−1 were prepared and applied to wheat durum seeds. The control group was given distilled water. In both studied varieties of durum wheat, only flowers’ aqueous extracts showed a significant positive allelopathic effect by increasing the studied parameters, while leaves and roots from chamomile showed an inhibiting potential on germination and seedling growth in varieties riyad and kanakis.
Highlights
Durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn.) is an allotetraploid (2n 4x 28 chromosomes; genome formula MMUU), resulting from the intergeneric hybridization and polyploidization of two species of the Poaceae family, Triticum urartu and Aegilops speltoides [1]
Weeds are responsible for heavy yield losses in wheat because of their competition for water, nutrients, and light, as well as for their phytochemicals interference with wheat, posing a significant biological constraint to crop productivity [4]. e interactions between plants is called “Allelopathy,” which has been defined as the direct or indirect, detrimental or beneficial effects of one plant on another through the production of chemical compounds that escape into the environment, through leaching, root exudation, volatilization, and decomposition of plant residues [5]; as a result, it plays a significant role in plant dominance, succession, plant populations and climax vegetation development, and crop production [6, 7]. e substances involved in this biological phenomenon are plant
A lot of grain remains on the field and germinates throughout the subsequent cultivation. erefore, it is crucial to have a following crop tolerant to allelochemicals produced by camomile. roughout this short communication, we investigate the allelopathic effect of M. chamomilla aqueous extracts of various parts on seed germination and seedling growth of two Moroccan durum wheat varieties, namely, kanakis and riyad
Summary
Durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn.) is an allotetraploid (2n 4x 28 chromosomes; genome formula MMUU), resulting from the intergeneric hybridization and polyploidization of two species of the Poaceae family, Triticum urartu and Aegilops speltoides [1]. In Morocco, late rainfall delayed planting followed by adverse weather conditions, elevated temperatures from January to March, affected crop growth, and reduced production (4.02MT in 2020), and recent data collected from the FAO outline a decline in wheat production (in which durum) of 25.4%. Allelopathy is a recent branch of plant biology, and there is very little work carried out on the allelopathic potential of Moroccan flora on crops. Erefore, it is crucial to have a following crop tolerant to allelochemicals produced by camomile.
