Based on the tissue culture, the effect of N-phenyl-N'-1,2,3-thiadiazol-5-ylurea, 6- benzyla minoprine(6-BA) and 1-Naphthylacetic acid on spore germination, protonema develop- ment and bud differentiation in Entodon challenged was investigated in this paper. The whole process was observed and taken pictures. The results show that TDZ, 6-BA and NAA have no significant effect on the spore germination. During the process of protonema development, 1.0 mg/L NAA can promote the primary development of protonema significantly, and 0.4 mg/L TDZ promotes branches formation in inter- mediate stage of the protonema development.
:研究了3种植物生长调节剂苯基噻二唑基脲、6-苄基腺嘌呤(6-BA)、萘乙酸对密叶绢藓孢子萌发、原丝体发育及芽体发生的影响,并对整个发育过程进行了显微观察和照相,结果表明:(1)3种植物生长调节剂对密叶绢藓孢子萌发影响不显著;(2)在原丝体发育阶段,1.0mg/LNAA对原丝体初期的发育促进效果显著,0.4mg/LTDZ对原丝体发育中期分枝的形成促进效果显著,6。

Sinense, the spores germinate inside their exospores and then divide into massive protonemata;the massive protonemata can form two kinds of protonemata of which one is clubbed protonema with papillae,and the other is caulonema composed of long and cylindrical cells ; the gametophyte archaeocytes only occur on the massive protonemata.

The spores of Cheilolejeunea ventricosa X.L.He were cultured on MS media (without acid and vitamin, pH=6.2, with 1% agar and 1% sucrose). The sporeling development and oil body ontogeny were observed. After a 55-day-long axenic culture, young plants were obtained successfully. Sodium hypochlorite solution was used to sterilize the capsules. Our results revealed that the sterilizing treatment with 0.1% Sodium hypochlorite solution for a period of 5 seconds was optimal. Oil bodies in primary protonemata are nearly homogeneous, but distinctly compound in the leaf cells of the primary leafy shoots.
首次研究了膨叶唇鳞苔的孢子萌发、原丝体和油体发育及配子体发生的过程,结果表明:(1)使用经过改良的MS培养基(不加氨基酸和维生素,pH值为6.2,琼脂和蔗糖浓度均为1%)能在55 d左右的时间利用孢子培养获得植物体;(2)用0.1%的次氯酸钠溶液,消毒5 s是消毒孢子的最佳方案;(3)油体在孢子萌发初期为均一型,到幼叶发生后,成为可见的聚合型,但聚合的程度比野生材料要弱。
