“…Similarly, Petri dish and pot experiments as well as type of extraction of allelochemicals from plant biomass differed in their inhibitory effect. Application of extracts in petri dishes generally had higher phytotoxic effect compared to plant residues in soil probably as a result of direct contact of seeds with extracts on filter paper , Nekonam et al, 2014 and diffusion and adsorption of allelochemicals in the soil (Vidal et al, 1998). However, differences among plant residues and extracts from fresh biomass depended on the plant species.…”

“…For example, lovage residues and chamomile extracts had higher inhibitory potential compared to lovage extracts and chamomile residues. According to Nekonam et al (2014) some plant species have stronger inhibitory effect when applied as residues as a result of stronger extraction of allelochemicals during residues decomposition.…”

“…Both extracts and residues of saffron (Crocus sativus L.), pricklyburr (Datura inoxia Mill. ), tobacco (Nicotiana tabacum L.) and oleander (Nerium oleander L.) possess herbicidal potential against redroot pigweed (Amaranthus retroflexus L.) (Nekonam et al, 2014). Allelopathic effect of common mallow extracts and residues on crops was also reported (Qasem, 2010, Zahedi andAnsari, 2011).…”

The aim of the study was to evaluate the effect of six cultivated and wild aromatic and medicinal plants, basil (Ocimum basilicum L.), chamomile (Matricaria chamomilla L.), common mallow (Malva sylvestris L.), greater celandine (Chelidonium majus L.), lemon balm (Melissa officinalis L.) and lovage (Levisticum officinale Koch), on germination and growth of weed species scentless mayweed (Tripleurospermum inodorum (L.) C.H. Schultz). In total four experiments were conducted to assess the allelopathic potential of seed and plant aboveground biomass: I) seed cogermination in Petri dishes, II) seed cogermination in pots with soil, III) water extracts in Petri dishes and IV) plant residues in pots with soil. Weed seed germination was significantly reduced for 32.2% with lovage seeds in Petri dishes. In the pots with soil, seed allelopathic potential was less pronounced. The application of extracts from fresh plant biomass in concentrations of 5 and 10% reduced germination and growth of weed, with the extracts from chamomile and common mallow having the highest inhibitory effect. The extracts from dry plant biomass of basil, chamomile, common mallow, greater celandine and lovage in higher concentration completely (100%) inhibited germination and weed seedling growth. On average, the extracts from dry plant biomass had higher inhibitory effect. Reduction in weed seed emergence and growth was recorded when dry plant residues in rates of 10 and 20 g/kg were incorporated in the soil. Lovage and greater celandine residues exhibited the highest allelopathic effect.

“…The growth of the two target plant species in the presence of M. pigra leaf samples at different concentrations indicated the response was species-specific and concentration-dependent as well as depending on the properties of the allelochemicals. Nekonam et al (2014) suggested that variability in allelopathic expression in a plant might be due to the different nature of allelochemicals released by the species. There are various direct modes of action of allelochemicals on plant growth and metabolism, cell division, cell elongation, membrane permeability, mineral uptake, photosynthesis, respiration and specific enzyme activity, whereas there are indirect effects on soil properties and nutrient cycling (Rice, 1984;Weir et al, 2004;Farooq et al, 2013;Hernández-Aro et al, 2016).…”

To cite this paper: Koodkaew, I. and R. Rottasa, 2017. Allelopathic effects of giant sensitive plant (Mimosa pigra) leaf powder on germination and growth of popping pod and purslane. AbstractThe most of invasive alien species possess allelopathic properties for beneficial success in site establishment. Giant sensitive plant (Mimosa pigra L.) is an important invasive species in nature. The objective of this study was to evaluate the allelopathic activity of M. pigra leaf residues on the germination, survival percentage and growth in two weeds, namely popping pod (Ruellia tuberosa L.) and purslane (Portulaca oleracea L.). Experiments were carried out under laboratory (agar medium) and greenhouse (soil medium) conditions with the addition the M. pigra leaf powder at varying concentrations of 1, 2, 3 and 4% (w/w) into the agar and soil medium. Negative and positive effects of M. pigra leaf residues were assessed. The results under two conditions showed the same trend, namely that the M. pigra leaf samples expressed inhibitory effects on the germination, survival percentage and growth of popping pod and exhibited stimulatory effects on purslane for all parameters. The soil experiment showed more prominent effects than the laboratory bioassay, with the dry biomass of popping pod being decreased up to 70.27% whereas the dry biomass of purslane sharply increased up to 1,562.50% and the effects became stronger when the concentration of M. pigra increased. The results indicated that the allelopathic effects of M. pigra were species-specific and concentration-dependent. The M. pigra leaf residues could be considered as a source of biologically active compounds.

“…The reduction resulting from Eucalyptus leaf compost is more severe. Sabagh Nekonam et al (2014) studied the allelopathic effects of Crocus sativus L., Ricinus communis L., Nicotiana tabacum L., Datura inoxia Mill., Nerium oleander L., and Sorghum vulgare L. on the germination and growth of Amaranthus retroflexus L. (redroot pigweed). All aqueous extracts showed significant inhibitory effects on the germination, seedling length and weight of redroot pigweed plants under laboratory conditions and extracts and the powder of these plants showed significant inhibitory effects on pigweed dry weight, height, leaf area, the number of survivor plants, and the amount of chlorophyll under greenhouse conditions.…”

Forty safflower genotypes were grown under normal irrigation and drought stress. In the first experiment, the allelopathic potential of shoot residues was evaluated using the sandwich method. Each genotype residue (0.4 g) was placed in a sterile Petri dish and two layers of agar were poured on that. Radish seeds were placed on agar medium. The radish seeds were cultivated without safflower residues as the controls. The length of the radicle, hypocotyl, and fresh biomass weight and seed germination percentages were measured. A pot experiment was also done on two genotypes with the highest and two with the lowest allelopathic activity selected after screening genotypes in the first experiment. Before entering the reproductive phase, irrigation treatments (normal irrigation and drought stress) were applied. Shoots were harvested, dried, milled and mixed with the topsoil of new pots and then radish seeds were sown. The pots with safflower genotypes were used to evaluate the effect of root residue allelopathy. The shoot length, fresh biomass weight, and germination percentage were measured. Different safflower genotypes showed varied allelopathic potential. The results of the first experiment showed that Egypt and Iran-Khorasan genotypes caused maximum inhibitory responses and Australia and Iran-Kerman genotypes resulted in minimum inhibitory responses on radish seedling growth. Fresh biomass weight had the most sensitivity to safflower residues. The results of the pot experiment were consistent with the results of in vitro experiments. Residues produced under drought stress had more inhibitory effects on the measured traits. Safflower root residue may have a higher level of allelochemicals or different allelochemicals than shoot residue.
