to study the effects of integration of mechanical control with herbicides on yield and yield components of soybean (glycine max) a field experiment was conducted during 2003-2004 at the research farm of agronomy department, agriculture campus of tehran university, karaj. a randomized complete block design (rcbd) of 18 treatments was applied, each treatment being replicated 3 times. treatments i...
Polyploids of many species horticultural plants are widely used in breeding programs since they characterized by vigorous growth, larger organs, and greater resistance to biotic abiotic stress. Saskatoon berry (Amelanchier alnifolia Nutt.) is a form diploid (2n = 2x 34) tetraploid. So far, no reports on induction polyploidy this have been found. The aim the study was obtain octoploids with use ...
in order to investigate the effect of chemical herbicides on control of broad leaf weeds of common bean, an experiment was conducted in 2007 at yasouj with 12 treatments in a randomized complete block design with 3 replications. treatments consisted of preplant application of trifluralin herbicide at 960 g ai ha-1; postemergence application of bentazon at 1200 g ai ha-1; imaztapir at 50, 75 and...
Polyploidy induction in German chamomile (Matricaria chamomilla L.) by herbicide trifluralin Leila Karami1, Mohammad Modarresi2, Mohammad Amin Kohanmoo2, Fatemeh Zahabi Ahmadi2 & Saeed Irian3 1Department of Horticulture, Faculty of Agriculture and Natural Resources, Persian Gulf University, Bushehr, 7516913817, Iran; 2Department of Plant Breeding, Faculty of Agriculture and Natural Resourc...
Background: Herbicides are widely used in agriculture to kill a large variety of unwanted weeds. However, the application in water ecosystems may pose harmful impacts on the health of aquatic organisms. We studied the acute toxicity of four major types of herbicides on the survival of adult shrimp, Artemia franciscana (AF). Methods: The brine shrimp, AF, was hatched from the commercially encys...
HIGHLIGHTS The longevity of the female and male Drosophila melanogaster is improved at doses given Aloe vera. Trifluralin has been observed to cause DNA damage, while vera shown reduce damage. reduced larval survival rate, increased rate high concentration.
Interaction between herbicides and sediments in water systems is an important process occurring in water, which influences the behaviour of the herbicides in water. This paper reports on the sorption of herbicides norflurazon, oxadiazon and trifluralin on soil and the interaction between the herbicides and sediments under stirred and non-stirred conditions. The sorption coefficients of the herb...
Background: Evaluation of herbicide pollution in aquatic environments needs the great concern and the most important echo-pollutant effects of herbicides are related to their effects on non target aquatic organisms. Native fish can serve as a proper bio-indicator for evaluation of pollution on aquatic ecosystems. OBJECTIVES: To find environmentally friendly herbicides, in this study the acute ...
