ALLELO CHEMICALS OF ARTEMISIA VULGARIS AND ASTRAGALUS SPECIES EFFECT ON SEED GERMINATION OF BRASSICA FAMILY

The secondary metabolites released and Synthesis having Allelopathic interaction are called allelochemicals, All plants have allelopathic effects on the surrounding plants through releasing allelochemicals in environment, through biochemical reaction several biological changes are introduced such biochemical are released from all parts of plants, that allelochemicals interfere in seed germination. Astragalusand Artemisia Vulgaris both the plants have significant uses medicinally, both the plants showed significant deference in the germination of Brassica family.There have been increase in the germination of all seeds by the concentration of Astragaluswith dose 0.5g/100ml, 1g/100ml, 1.5g/100ml, 2g/100ml, and 3g/100ml. increase in doses showed increase in germination percentage accordingly, the mustered showed increase from 78% to 91% with 3g/100ml meanwhile 68% to 89% was of Rap, 76% to 83% was Turnip and radish also showed increase in germination the minimum was 80% without extract and 84% with 3g/100ml and it was the only one which showed less germination among others. Artemisia Vulgaris also showed significant deference in the germination which was statically proved probation value was less then <0.05 as with Astragalus but in this case the germination was decreased according to increase in Doses, Mustard maximum germination was 78% without extract and the decrease was 39% with 3g/100ml, rap was 64% decreased tell 51%, Turnip was 79% which was decreased tell 39% accordingly Radish showed decrease in germination from 77% tell 31% all brassica family showed significant deference with both plants extracts, the study need farther research on these plants.
