Abstract:The effects of different concentrations of lead stress on seed germination and seedlings growth of wheat were studied using wheat variety Dekang 961 as test material,it conducted 7 Pb concentrations(5,50,200, 300,400,500 and 600 mg/L),and with water as a control.The results showed that seed germination rate and vigor index,seedlings germinal length and root length of wheat under Pb concentration of 5 and 50 mg/L were all higher than that of CK.When Pb stress concentration was more than or equal to 200 mg/L,it could inhibit the seed germination and seedling bud and root growth,of which the inhibitory effect of Pb on root of wheat seedlings was greater than that on bud.Wheat seedling germination potential and germination index were more than that of CK if the concentration of Pb was less than or equal to 400 mg/L,thereby the uniformity of seed germination was increased. The fresh weight and dry weight of seedlings of wheat under the concentration of 5 mg/L were all higher than that of CK,and the nutrient uptake and dry matter accumulation in wheat seedling were inhibited when the concentration of Pb was greater than or equal to 50 mg/L.The coleoptile length of wheat treated with Pb were less than or equal to CK. With the increase of Pb stress concentration,the inhibition effect of Pb on seed germination and seedling growth of wheat was enhanced.

Abstract:Using randomized block experimental design,eight sowing times were designed including April 1,April 15,May 1, May 15, June 1, June 15, July 1, July 15,the harvest time of Radix Isatidis  was October 20.According to the requirements of Chinese Pharmacopoeia 2010 Edition,the yield of Radix Isatidis  was measured after dried, then broken to determine the contents of nucleoside(guanosine, uridine, adenosine) and (R,S)-goitrin in Radix Isatidis  by HPLC,then the effects of sowing date on total nucleosides content,(R,S)-goitrin content and yield of Radix Isatidis were analyzed to determine the optimum sowing date of Radix Isatidis.The results showed that the total nucleosides content of plant sowed at May 15 reached the highest,which was 0.176 %,the (R,S)-goitrin content and yield which sowed at April 1 reached the highest,they were 0.368% and 0.336 kg/m2. Comprehensive comparison the dynamic changes of different sowing time in total nucleoside content,(R,S)-epigoitrin and yield of Radix Isatidis,the best sowing time was about April 1,the result provided the scientific basis for the optimum sowing date determination and standardized cultivation of Radix Isatidis.
