This study aimed to investigate the allelopathic effects of Oldeania alpina leaves aqueous extract on germination and initial growth of barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) test crops in a laboratory experiment. To this end, different aqueous extract concentrations (0%, 2.5%, 5%, 7.5%, and 10%) were prepared and used to irrigate seeds of test crops. The effect of the extract was tested by placing a set of 50 seeds of barley and wheat separately in six replicates of Petri dishes using a completely randomized design. Besides, four different solvents (hexane, ethyl acetate, methanol, and water) were used to prepare O. alpina leaves extracts and subjected to qualitative analysis of nine selected allelochemical compounds namely; flavonoids, phenols, tannins, terpenoids, steroids, quinones, coumarins, saponin and, anthraquinones. Data were analyzed using both descriptive and inferential statistics by SPSS software version 27. The study results showed a significant (p < 0.05) concentrations-based inhibitory effect of O. alpina leaves extract on germination parameters and initial growth of the two tested crops. In addition, it showed the presence of all tested allelochemicals except Anthraquinones in O. alpina leaves extracts. However, further field study would be necessary to evaluate and confirm the findings on a natural soil condition.

“…From the above results, water-soluble extract of A. argyi powder exhibited the strongest allelopathic effects on plant growth. To evaluate systematacially, the germination rate, germination rate index, germination index, root length, stem length and biomass were selected as the allelopathic response indexes as previously reported 12 , 13 .

Allelopathy means that one plant produces chemical substances to affect the growth and development of other plants. Usually, allelochemicals can stimulate or inhibit the germination and growth of plants, which have been considered as potential strategy for drug development of environmentally friendly biological herbicides. Obviously, the discovery of plant materials with extensive sources, low cost and markedly allelopathic effect will have far-reaching ecological impacts as the biological herbicide. At present, a large number of researches have already reported that certain plant-derived allelochemicals can inhibit weed growth. In this study, the allelopathic effect of Artemisia argyi was investigated via a series of laboratory experiments and field trial. Firstly, water-soluble extracts exhibited the strongest allelopathic inhibitory effects on various plants under incubator conditions, after the different extracts authenticated by UPLC-Q-TOF-MS. Then, the allelopathic effect of the A. argyi was systematacially evaluated on the seed germination and growth of Brassica pekinensis, Lactuca sativa, Oryza sativa, Portulaca oleracea, Oxalis corniculata and Setaria viridis in pot experiments, it suggested that the A. argyi could inhibit both dicotyledons and monocotyledons not only by seed germination but also by seedling growth. Furthermore, field trial showed that the A. argyi significantly inhibited the growth of weeds in Chrysanthemum morifolium field with no adverse effect on the growth of C. morifolium. At last, RNA-Seq analysis and key gene detection analysis indicated that A.argyi inhibited the germination and growth of weed via multi-targets and multi-paths while the inhibiting of chlorophyll synthesis of target plants was one of the key mechanisms. In summary, the A. argyi was confirmed as a potential raw material for the development of preventive herbicides against various weeds in this research. Importantly, this discovery maybe provide scientific evidence for the research and development of environmentally friendly herbicides in the future.

“…From laboratory studies, there is evidence that the genus Populus possesses allelopathic activity. Leaf extracts from P. nigra , P. tremula and P. deltoides have been shown to reduce germination of cereals and other plant species (Hachani et al, 2019; Inayat et al., 2019, 2020; Singh et al, 2012; Zubay et al., 2021).…”

Competition, stress and benefits: Trees and crops in the transition zone of a temperate short rotation alley cropping agroforestry system

Tree strips on agricultural production sites offer many economic, ecological and social advantages. However, the introduction of trees creates a transition zone between tree strips and crop land. Here, trees and crop plants compete for resources such as space, nutrients, water and light, which causes stress in the low‐competitive system. On the other hand, facilitation such as additional nutrient input through tree leaf litter and fine roots are possible. This study aims to provide indications for competition and benefits that can arise for plants growing in the transition zone of a temperate short rotation alley cropping agroforestry system (SRACS). Various climatic and plant‐growth parameters were investigated between 2013 and 2019 at different positions of an SRACS with fast‐growing poplars in northern Germany. Reduced yield of wheat, oilseed rape and silage maize close to the tree strip was associated with greater soil water tension in 30 and 60 cm soil depth due to the presence of poplar roots, reduced solar radiation due to tree shading and leaf litter coverage. In contrast, poplars growing in the outer rows produced more biomass than those in the inner rows due to the additional availability of space, light and nutrients taken from the crop field. Trees in the transition zone seem to be competitive with arable crops, but without effect on the average long‐term yield of arable crops.
