Weeds are plant disturbing organism that affect yields through competition and allelopathy. However, not much is known about weed diversity in swamps, so research needed to identify their types compounds as a control strategy. This study was conducted using survey method from January March 2020 at the Barito Kuala District, South Kalimantan. Thirty villages were randomly selected each of eight ...

abstract most allelopathic studies have demonstrated the importance of live and dead plant tissues as source of allelochemicals. seeds of several species also have inhibitory effects on germination of the same or other species. in order to determine the allelopathic effects of common lambsquarters (chenopodium album) seeds, an experiment was conducted under controlled conditions in birjand univ...

abstract one basic method of improving rangelands in a country is the use of native as well as exotic species of plants adaptable. among the but introduced species, atriplex canescens has been introduced in many rangelands, but it is important and necessary to consider it’s effects on native species. in the current study the effect of chemical competition (allelopathy) of atriplex canescens on ...

As climate change continues to alter seawater temperature and chemistry on a global scale, coral reefs show multiple signs of degradation. One natural process that could facilitate the recovery of reef ecosystems is coral recruitment, which can be influenced by the benthic organisms in a local habitat. We experimentally tested both a global stressor (increased seawater temperature) and a local ...

The belowground mechanisms facilitating invasion and proliferation of non-native plant species into natural communities are of critical importance for understanding plant invasions. Research on allelopathy suggests that some exotic plant species produce compounds via root exudates that may suppress or inhibit the growth of neighboring plants, but the specific mechanisms and consequences of thes...

Recent research of the Agricultural Research Service of USDA on the use of natural products to manage pests is summarized. Studies of the use of both phytochemicals and diatomaceous earth to manage insect pests are discussed. Chemically characterized compounds, such as a saponin from pepper (Capsicum frutescens L), benzaldehyde, chitosan and 2-deoxy-D-glucose are being studied as natural fungic...
