Leaf explants of Nicotiana tabacum were grown on MS basic medium supplemented 2 ppm 6 BA,and irra-diated with different doses (0,1,000,3,000,5,000,10,000,15,000,Rad) of ~(60)Co-γ-ray at different times (3,6,9,12,15,day).Results obtained show-ed that the rediosentivity of the cultured cells in different conditions of growth and development were dif-ferent in their responses.Cell dif-ferentiation was not inhibited by ir-radiation with 1,000 Rad treatment.Explants exposed to 5,000 Rad on the 6th day of cultivation...

Leaf explants of Nicotiana tabacum were grown on MS basic medium supplemented 2 ppm 6 BA,and irra-diated with different doses (0,1,000,3,000,5,000,10,000,15,000,Rad) of ~(60)Co-γ-ray at different times (3,6,9,12,15,day).Results obtained show-ed that the rediosentivity of the cultured cells in different conditions of growth and development were dif-ferent in their responses.Cell dif-ferentiation was not inhibited by ir-radiation with 1,000 Rad treatment.Explants exposed to 5,000 Rad on the 6th day of cultivation the cell dif-ferentiation was inhibited,but those treated on the 9th and 12th day of cultivation were only partially inhibit-ed (differentiation rate 8-55%).Cult-ures irradiated with 3,000 Rad on the 3 rd day,the differentiation rate was only 28%,whereas those irradiated on the 9 th day with the same dosage were 100% differentiated.Explantirradiated with 1,000 Rad differentiat-ed into normal shoots,but when treated on the 3rd day,more abnormal shoots were developed,whereas the explants exposed to irradiation from ~(60)Co above 5,000 Rad,more abnormal shoots were developed than those treated with 1,000 Rad.The abnor-mal shoots were not differentiated into roots and were difficult to transplant.When the explants were irradiated on the 15th day of cultivation with 15,000 Rad the ability of differentiation was inhibited,however a few normal plant-lets occured.From the behavior of the flower variation of the induced mutagenic plant,it was found that when the explants were irradiated with 1,000 Rad on the 12 th day of cul-tivation,the flower variation of the induced mutagenic plant was quite evident.The optimal efficient irradia-tion doses for inducing flower variation were discussed.

实验结果表明,培养时期不同的细胞,对γ射线辐照敏感性不同,就分化而言,1,000 Rad处理不抑制细胞分化。培养3天时用3,000 Rad处理分化率仅28%,而同样剂量在9天时处理100%分化。在培养3、6天时用5,000 Rad辐照处理完全抑制细胞分化,而培养9、12天时部分抑制(分化率仅8—55%)。从幼苗生长状态而言,培养3天时处理出现的畸形苗较多,6,000 Rad处理的畸形苗更多,畸形苗都不易生根,难于移植。从诱变花器官变异的表现而论,培养12天时经1,000Radγ射线处理的变异植株花器官变异更明显,植株畸形,花冠淡绿色并有粉红色小点,雄蕊花丝短,花药位于柱头下位约花柱全长1/2处,故整株花朵不育。由此可见,以诱发花器官变异为目的,似乎不能简单地根据细胞存活力与分化率的大小来衡量,似乎在组织分化芽原基时比细胞处于脱分化阶段时处理更有利。另外观察到经γ射线诱发的变异植株,其叶片的分化能力有抗辐射效应。

This paper reports the organ differentiation in the tissue culture of Begonia fimbristi- pula Hance.Three types of regenerated planttets were obtained:(1)Callus differentiation (2)growth center induced from the aseptic seedling leaf and(3)shoots were differentiated from roots developed from the callus.Callus could be obtained on SH medium as well as on MS basic medium supplemented with 2,4-D( 0.1ppm)+NAA(2.5ppm)+KT(0.25ppm). Experiments were carried out to compare the effects of different concentrations of sucrose on callus induction.It was found that the differentiation rate of callus was higher on MS medi- um than on SH medium.Comparitive experiments were also carried out to find out the effi- ciency of callus differentiation by BA and 2ip at verious concentrations.The Better diffe- rentiation of callus was obtained at the range 0.25—2 ppm of BA.The cytological inve- stigations showed that individual plantlet grown on the leaf was originated from the epi- dermal cells. According to our study,numerous plantlets can be obtained from a single leaf of asep- tic seedlings.It is possible that this technique provides a way of rapid clonal propogation of Begonia fimbristipula Hance.

本文报道了紫背天葵种子、种胚异形苗及试管苗叶片的脱分化和植株再生的三种类型:(1)通过愈伤组织分化形成植株。(2)促使无菌苗叶片产生多生长中心,从而长成小植株。(3)由愈伤组织分化根后再分化出芽而成植株。在以 SH 培养基附加0.5 ppm 2,4-D、2ppmP-CPA、0.1ppmKT 和 MS 培养基附加0.1ppm 2,4-D、2.5ppm NAA、0.25ppm KT 得到愈伤组织。比较了不同浓度的 2,4-D 和不同浓度的蔗糖对愈伤组织发生的效应,得出1ppm2,4-D 效果好,蔗糖以3%为宜。发现愈伤组织来源于 MS 及用 MS 为基础的分化培养基,分别比来源于 SH 及用 SH 为基础的分化培养基的分化效率高。比较试验了 BA 和2ip 的分化效率,在0.25—2ppm 范围内 BA 对紫背天葵愈伤组织分化效率高。细胞学实验表明,叶片长出的小植株起源于表皮细胞。利用试管无菌苗叶片直接诱导植株的方法,可作为快速无性繁殖紫背天葵的手段。

The rice varieties were made in a complet set of 5×5 diallel crosses, and were anther cultured in dediffrentiation and differentiation media. The genetic basis of the callus inducing rate, total differentiation rate and green plantlet rate were analyzed by Hayman method (1954). Analysis of variance indicates the significant difference existed in the variance of genotypes, however, linear regression of Wr by Vr was not reach significant level. Wr+Vr analysis reveals that the cytoplasmic and epistatic effects influence the culture ability in addition to additive effects. WrVr graph of three characters mentioned above was drawn following Askel and Johnson (1956). Similar distribution of 5 arrays were observed, and the expect regression line was below zero point, indicating the relatively higher overdominance. Therefore, the genotype of the parents is of the cause controlling the anther culture ability.

以水稻藤板5号等为材料。进行(5×5)杂交及花粉培养。按Hayman双列法,分析了愈伤组织诱导率、分化率及绿苗再生率的遗传背景。方差分析表明遗传型变异显著,而Wr依Vr的线性回归未达显著水平。Wr+Vr分折证实除加性作用外,细胞质效应及上位效应也影响培养力的高下。按Askel和Johnson法分别绘制了三个性状的WrVr图,各阵点分布一致,理论回归线通过零点下方,说明存在较强的超显性作用。亲本遗传型是影响花药培养力的要素。
