Abstract:
Taking Echium vulgare L. seeds as materials,effect of different colchicines concentrations(CK,0.05%,0.10%,0.20%,0.30%,0.40%)and soaking times(12 hours,24 hours,36 hours,48 hours) on germination and seedling growth of Echium vulgare L. seed were studied.The results showed that,with the increase of colchicines concentration,the growth of germination and seedling had a highly depressed promotion and a certain distortion rate;obviously,with the increase of concentration,the surface of the blade became hypertrophy with dark green.Between the germination rate and germination potential of Echium vulgare L.seeds showed a lower phenomenon with the increase of concentration and soaking time.When the concentration was 0.40% and the soaking time was 48 hours,the germination rate was 36%,the germination potential was 16%.As the increase of concentration,the height and length of leaves at seedling stage was gradually reduced and the leaf width became larger,with a short vitality.
