“…The determination of proline content may be so important in the assessment of the physiological state, more generally to understand stress tolerance in plants (Zhang et al, 2013). Reduction observed in the levels of proline in the study may be due to the mobilization of proline in order to combat the threat posed by the extract (El-Shora et al, 2018). Proline mobilization under stress may perform the role of low molecular weight chaperones.…”

This study examined the phytotoxicity of the extract of Datura metel. It involved the planting of seeds of monocot, yellow maize (Zea mays) and a dicot, brown bean (Phaseolus vulgaris), growth and analysis of seedlings of the two plants.Seeds of Z. mays were collected at the Institute of Agricultural Research and Training (IAR&T), Ibadan and the seeds of P. vulgaris were collected at International Institute for Tropical Agriculture (IITA), Ibadan, Nigeria. The leaf of D. metel was collected. The plant was identified and authenticated (FHI 111862) at Forestry Research Institute of Nigeria (FRIN) Ibadan, Nigeria. The collected leaves were carefully washed under running tap water and air-dried at room temperature for four weeks. The dry leaves were milled into a fine powder and extracted. The phytotoxic potentials of the extract were evaluated using a standard method. At the end of the experiment, seedlings were harvested, stem and leaf were separately collected, and shoot length of seedlings was measured, and kept frozen for the estimation of total protein, soluble sugar, free amino acids, proline, and plant pigments.The findings revealed that different concentrations of aqueous extract of the leaf of D. metel retarded the rate of germination of seeds, significantly inhibited the shoot length of P. vulgaris and Z. mays and reduced concentrations of chlorophyll, free amino acids, protein, sugar, and proline.In conclusion, this study revealed that the extract exhibited a deleterious effect on germination, growth and biochemical parameters in seedlings of P. vulgaris and Z. mays.

“…The presence of D. stramonium aqueous extracts might have interfered with photosynthesis leading to drastic changes in the physiology of plants. Reduction in photosynthesis might have led to reduced plant growth and reduced fresh biomass accumulation due to reduced water content in the tested species (EL-Shora et al, 2018). According to Oyun (2006), allelochemicals inhibit water absorption which is a precursor to physiological processes like photosynthesis.…”

Datura stramonium extracts have allelopathic properties. The study was conducted to investigate the allelopathic effects of D. stramonium weed on seed germination, early seedling growth and dry biomass of crop plants (Triticum aestivum and Vigna unguiculata). Laboratory and greenhouse trials were arranged as completely randomised design and the field pot experiment was arranged as a randomised complete block design. Aqueous leaf extracts of D. stramonium at 2, 4, 6 and 8% concentrations were applied to determine their effects on seed germination, early seedling growth of crops under laboratory, field and greenhouse conditions. Distilled water (0%) acted as a control. Results from the study indicated that germination, shoot length and dry weight significantly decreased proportionally (p<0.001) as the concentration increased from 2 to 8%. The results showed that D. stramonium has allelopathic effects on wheat and cowpeas, hence cannot be used as a bio herbicide to control Tagetes minuta and Amaranthus hybridus on the selected crops since it is non selective to the crops studied. There is therefore need for further research on screening of arable crops against the allelopathic effects of D. stramonium. This will help to identify arable crops which are not negatively affected by allelochemicals from D. stramonium weed so that it can be used as a selective bio herbicide against other weeds.

“…These include, among others, germination behavior and other physio-biochemical responses of test species 11,12,13,14,15,16 . With considerable evidences adduced during the past few decades demonstrating the presence of inhibitory compounds in a wide variety of plant types and plant parts, the recent upsurge of interest in allelopathy, with major volumes of collected papers, books, journals regularly published 17,18,19 has established the topic as one of biological importance. In recent times it is focused on establishing research procedures which may improve the importance of evaluations of the allelopathic potential of exotic nonnative weeds Chromolaena odorata and Lantana camara which have become invasive and forms monospecific stands in different ecosystems in West Bengal and surroundings 20 .…”

Chromolaena and Lantana plants were analyzed to evaluate the existence of allelopathic effect using fully viable seeds of mung bean as the bioassay material. The study shows that pretreatment of mung bean seeds with various concentrations [1:1 and 1:2 (w/v)] of Chromolaena and Lantana leaf leachate for 24 h interval reduced the percentage germination. DNA and RNA contents were significantly reduced with a remarkable increase of amylase activity in seed samples pretreated with leaf leachate of Chromolaena and Lantana. The seedling performance was found to be much poor when the seedlings were raised from seeds which underwent pretreatment with the plant leachates. Evidenced from the lower levels of chlorophyll, DNA and RNA as well as a higher level of amylase activity in leaves of seedlings. Leaf leachate causes the reduction of germinability and influenced activity of amylase enzyme being the important allelopathic indices; it can be concluded that Chromolaena and Lantana can potentially render allelopathic action on mung bean. It further reemphasizes the fact that fast-growing exotic invasive weeds like Chromolaena and Lantana having inhibiting property should be treated as a potential threat to plant diversity in a natural ecosystem.
