Allelopathic effects of apricot (Prunus armeniaca L.) root on some crops and weeds
Allelopathic effect of apricot (Prunus armeniaca L.) root on some crops and weeds was investigated in two independent experiments. First, the effect of concentrations aqueous extract of apricot root (AAR) was assayed on the seed germination of Cicer arietinum L., Phaseolus vulgaris L., Triticum aestivum L., Zea mays L., Amaranthus retroflexus L., Secale cereal L., and Avena ludoviciana Durieu. ...
متن کاملEvaluation of the Allelopathic Potential of Some Weeds on Germination Characteristics and Photosynthetic Pigments of Cress Seedlings (Lepidium sativum)
DOR: 98.1000/2383-1251.1398.6.129.11.1.1575.41 Extended abstract Introduction: Interference includes competition for environmental potentials and allelopathy. By releasing chemical compounds, usually of secondary metabolites, in various ways such as root exudation, decomposition, leaching and volatilization, allelopathic weeds may have positive, negative or even neutral effects on crops. ...
متن کاملHerbicide Resistant Weeds and Crops
Modern herbicidal weed control often exploits physiological differences among plants and takes advantage of herbicide tolerance or resistance in crop plants to bring about the selective removal of susceptible weeds. The Weed Science Society of America defines herbicide tolerance as “the inherent ability of a plant to survive and reproduce after herbicide treatment” which suggests that herbicide...
متن کاملInteractions among leguminous trees, crops and weeds in a no-till alley cropping system
Trees improve the soil quality and their rapid growth in the tropics make agroforestry systems potentially effective for establishing low-input agricultural systems in this region. This study assessed the effects of the biophysical interactions among leguminous trees, weeds, cotton and maize in an alley cropping system. The experiment comprised six treatments: Clitoria + Gliricidia; Acacia ...
متن کاملAllelopathic Potential of White Top and Syrian Sage on Vegetable Crops
However, the inhibitory materials may be autoinhibitory or heteroinhibitory (Kumari and Kohli, 1987), some White top [Cardaria draba (L.) Desv.] and Syrian sage (Salvia can be highly selective (Stachon and Zimdahl, 1980; syriaca L.) are noxious common weeds of field crops and orchards Sahid and Sugau, 1993), and their effect is concentration in Jordan. This study was conducted to investigate an...
