And then adding NAA at low concentration in MS was used to give rise to roots. We also found that lower level of hormone could control effectively browninng and vitrifaction during the culture and G1 n (6mg/L) and AgNOj (2mg/L) supplemented in shoot induction media could improve the shoot information rates apparently (about90%).The whole period of plant regeneration from leaflets of peanut could be divided as five steps: germination - shoot induction -shoot elongation-rooting- tranplant.
用1/2MS培养基萌发花生种子,9-10d后,从无菌花生苗上切取幼嫩叶片中部为外植体。2500Lux光照和27±1℃条件下,在诱芽培养基(MS+BA3mg/L+NAA0.8mg/L+AgNO_32mg/L十Gln 6mg/L)培养12-14d即可观察到明显芽点或瘤状突起,较前人报道的培养时间大大缩短了,4w后芽点进一步发育成丛生芽,芽诱导率达90.2%,每个外植体平均产9个丛尘芽,然后转至培养基MS+BA3 mg/L+AgNO_32 mg/L上诱导芽的伸长,3-4w后可长至3-4cm,切下带有2-3片叶片的幼芽移至生根培养基(MS+NAA0.8mg/L+AgNO_32mg/L),1w后切口处可见白色不定根形成。

For the bud directly differentiation , the suitable culture medium was MS+BA 2mg/L +NAA 0.2mg/L or MS+TDZ0.01mg/L +NAA0.2 mg/L, of which the induction rate was 88% and 100% respectively. An efficient tissue culture system has been developed with the bud of mature seed of Aesculus hippocastanum L. as explants . Buds were induced from 2cm high young plantlet cultured on MS medium supplemented with 0.6 mg/L 6-BA plus 0.1mg/L or 0.4~0.6mg/L ZT plus 0.1 mg/L NAA for 15 d, and the induction rate was 100%, the mean No. of buds was 35.7; The combination of MS+0.2mg/L 6-BA +0.1mg/L NAA + 10mg/L AD was the suitable culture medium for elongation of the buds.

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.
