Abstract

Because of abundance and importance of CONVOLVULUS ARVENSIS in WHEAT fields, an experiment was conducted as factorial with three replicates in 2oo7. Treatments were extract of CONVOLVULUS ARVENSIS (factor A) at five levels including leaf, shoot, root, and flower extracts and a control, and different concentrations of extracts (factor B) at 4 levels of 1:5, 1:10, 1:15, and 1:20. Results of analysis of variance showed significant effect of main factors and interactions on all attributes. All weed extracts decreased GERMINATION components but root extrac showed highest prohibition. Extracts of root and other parts of weed at 1:5 concetration inhibited GERMINATION at all. Leaf extract decreased radicle and plumole length, seedling dry weight, GERMINATION percentage and velocity as 99.41, 96.98, 100, 98.64, and 62.74%, respectively. Results of green house studies showed significant effect of some main factors and interactions on traits. İn low concentration, leaf extract and in high concentration, root extract showed higher effect on studied attributes. İncreasing extract concentration from 1:20 to 1:5, significantly decreased all attributes. Decreasing rate of plant height, spike length, leaf number, pedancle length, seed number, TKW, and YIELD in 1:5 concentration compared to control were 56.99, 50.44, 70,86, 62.4, 76.17, 94.66, and 99.01%, respectively. It was concluded that CONVOLVULUS ARVENSIS significantly decreased GERMINATION, GROWTH and YIELD of WHEAT duo to producing allelopatic chemical materials.
