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 کاملInoculation and Growth with Root Parasitic Weeds
A number of parasitic plants have become weeds, posing severe constraints to major crops including grain legumes. Breeding for resistance is acknowledged as the major component of an integrated control strategy. However, resistance against most parasitic weeds is difficult to access, scarce, of complex nature and of low heritability, making breeding for resistance a difficult task. Only moderat...
متن کاملAllelopathic Effects of Some Medicinal Plants Extracts on Seed Germination and Growth of Common Weeds in Mashhad Area
Allelopathy can be regarded as a component of biological control in which plants are used to reduce the vigour and development of other plants. Allelopathy refers to the direct or indirect chemical effects of one plant on the germination, growth, or development of neighbouring plants. The allelopathic effects of leaf extracts of Thymus vulgaris, Lavadula sp, Rosmarinus officinalis and Eucalyptu...
متن کاملNon-chemical Control of Root Parasitic Weeds with Biochar
This study tested whether soil-applied biochar can impact the seed germination and attachment of root parasitic weeds. Three hypotheses were evaluated: (i) biochar adsorbs host-exuded signaling molecules; (ii) biochar activates plants' innate system-wide defenses against invasion by the parasite; and (iii) biochar has a systemic influence on the amount of seed germination stimulant produced or ...
