Water extract effect of Datura fruit on emergence and early growth of wheat , barley ; toothed and rye grass seedlings .

Abstract

An experiment was conducted at Dept of Biology , Science college . Kufa Univ . on 2001 , to study the effect of Datura fruit extracts ( by cold and boiled water ) at a conc. of 0,25, 50,75 and 100% for germination percentage ; length of plumule ; length of radicle and radicle number , for four species wheat , barley , toothed and rye grass , that their seeds were sown in Petri- dishes that were covered in side by filter paper . Then , they watered by equal amounts of the above extracts conc . for ten days . The experiment was adopted by ( R.C.D) with three factors ; extract method , extract concentrations and plant species . Results indicated that , with both equous extracts for Datura fruit , and with all its concentrations the percentages emergence and the growth of tested plants for early period were reduced . Tested plants responded differently towards the extract effects and its concentrations . The severe effects were with toothed seedlings
