Weeds are known to cause enormous losses due their interference in agroecosystems. Because of environmental and human health concerns, worldwide efforts being made reduce the heavy reliance on synthetic herbicides that used control weeds. In this regard phenomenon allelopathy, which is expressed through release chemicals by a plant, has been suggested be one possible alternatives for achieving sustainable weed management. The use allelopathy controlling weeds could either directly utilizing...
The present review deals with the phenomenon of autotoxicity — a type intraspecific allelopathy, where plant species inhibits growth its own kind through release toxic chemicals into environment. This has been reported to occur in number weeds and crop plants agroecosystem wastelands causing soil sickness. Besides, it plays significant role orchards (of apple, pear, grapes, etc.) is major reason replant problem, natural forests coffee tea plantations regeneration problems. Not only higher...
Summary Allelopathy plays an important role in the agroecosys-tems leading to a wide array of interactions between crop-crop, crop-weed and tree-crops. Generally, these are harmful receiver plants but provide selective benefit donor. Soil microbes play key determining such as they not only alter nature allelopathic also modify expression allelochemicals. sickness problem croplands could be attributed property or even autotoxicity. The allelochemicals released largely by plant residues that...
Nitric Oxide (NO) is a bioactive signaling molecule that mediates variety of biotic and abiotic stresses. The present study investigated the role NO (as SNP [sodium nitroprusside]) in ameliorating lead (Pb)-toxicity Triticum aestivum (wheat) roots. Pb (50 250 μM) alone combination with (100 was given to hydroponically grown wheat roots for period 0–8 h. supplementation reduced accumulation oxidative stress markers (malondialdehyde, conjugated dienes, hydroxyl ions superoxide anion) decreased...
The herbicidal effect of volatile oils from leaves Eucalyptus citriodora against the noxious weed Parthenium hysterophorus was tested. In a laboratory bioassay, seed germination and seedling length, chlorophyll content respiratory activity decreased with increased concentration eucalypt 0.2 to 5.0 nL mL-1. Germination completely inhibited at mL-1 eucalyptus oils. Further, for 4-week-old plants sprayed different concentrations oils, visible damage 0 100 μL mL-1, week after spraying. At up 50...
Summary Allelopathy includes both positive and negative effects of one plant on the other through environment, though most studies seem to focus its deleterious impacts. It plays a key role in natural managed ecosystems. In agroecosystems, several weeds, crops, agroforestry trees fruit have been shown exert allelopathic influence thus, affecting their germination growth adversely. Some agricultural horticultural crops affect own seedlings grown succession which is commonly known as replant...
