The present article deals with an investigation on the anther culture in vitro of tobacco and red pepper. The tobacco anthers were cultured in vitro on 4 different media.Best result was obtained with Nitsch H medium;Blaydes was ledd effective.The percentage of the embryoids formation increases with the addition of 10—20%(v/v)cocoanut milk.The embryoids may be induced with sucrose from 1—4%;and 3% is the optimum. The anthers of different developmental stages were cultured in vitro for com- parison.It is found that when the anther with its pollen grains at the 1-nucleate stage,while the nucleus is situated on one side of the pollen,is the best material for haploid seedling induction. The embryoids were mainly formed in two ways:They were formed either from the development of equal division of the 1-nucleate pollen grain or from the vegetative nucleus of the unequal division of the 1-nucleate pollen grain.The generative nucleus may divide only once or several times but eventually the nucleus and its derivatives degenerate. The chromosome number of the root tip or shoot apex of the pollen plants is found to be n=24;the haploid nature of this plant was confirmed.Colchicine of different concentrations was used to double up the chromosomes of the haploid plantlets.In this way many diploids were obtained and among them a few were tetraploids.The production of the embryoids by different means was discussed. The red pepper anthers were cultured in vitro on NT and MS media,supplemented with different growth substances at the stage when its only nucleus is situated on one side of the pollen grain.The anthers gave rise to embryoids and calli.The develop- ment of the 1-nucleate pollen grain through“proembryo”to the formation of the seed- ling was observed.The development of the embryoids is similar to that of the zygotic embryo. The development of the embryoids from the pollen grains may cease to grow at any stage,hence a few of them may develop into seedlings. The connection between the multicellular“proembryo”and the pollen grain can be seen.The cells inside the pollen grain are large and stained lightly,while the cells of the embryoids outside the pollen grain are small,meristematic and closely arranged; some of them being in the initial stage of differentiation. The cells of the root tip and the callus have been examined with aceto-carmine squash method.The chromosome number was found to be n=12;therefore these plants and calli are haploids.

本文报道关于菸草和辣椒花药离体培养的研究结果。对于菸草花药离体培养曾进行四种培养基的对比试验,结果以 NH 效果最好,Blaydes 次之。10—20%(体积/体积)椰乳能提高花药成胚的百分比,对单倍体幼苗也有促进作用。蔗糖浓度从1—4%都能产生“胚状体”,以3%的蔗糖浓度产生“胚状体”的百分比最高,长出的幼苗也比较健壮。对花粉不同发育时期进行了比较试验,花药中花粉单核靠边时期进行培养的出苗率最高。“胚状体”的形成主要由单核花粉粒均等分裂或由营养核分裂两种方式形成“胚状体”。生殖核只进行几次分裂而最后逐渐退化消失。对菸草花粉植株进行根尖或茎尖制片,观察其染色体数目为24,证明是单倍体。用不同浓度的秋水仙碱对单倍体植株进行染色体加倍,得到许多二倍体后代,其中少数是四倍体。本文对花药离体培养和组织培养中产生“胚状体”问题进行了讨论。辣椒采用花粉单核靠边时期的花药,培养在 NT 及 MS 加有补充物质的培养基上,花药既产生“胚状体”又产生愈伤组织。观察到单核花粉最初分裂发育成多细胞“原胚”到最后形成幼苗的过程。“胚状体”的发育与合子胚的发育过程相似。在花粉发育成幼苗的各个发育时期都可能停止发育,长成幼苗的只是少数。...

The present paper deals with the main experimental results about the anther cul- ture in maize.Induction frequency varies with the different varieties and it is the highest when the excised anthers with the pollen grains at the middle-uninuclear stage are inoculated. Induction frcguency of pollen embryoids or calli increases apparently when the medium is added with 500 mg/l casein hydrolysate,0.5% active carbon and 15% sucrose. Four different pathways of androgenesis have been observed:Pathway of vegetative cell,pathway of generative cell,pathway of vegetative and generative cell in mixed development and pathway of equal division of the uninuclear pollen grain.All these pathway of development have been discussed.

本文报道了玉米花药培养的主要结果。品种之间诱导频率差异很显著。接种花药时,花粉单核中期诱导频率最高。培养基中加入500毫克/升酪朊水解物,0.5%活性炭,15%蔗糖能显著提高花粉胚状体和愈伤组织的诱导频率。在雄核发育的研究中,观察到有营养细胞发育途径,生殖细胞发育途径,营养细胞和生殖细胞混合发育途径,以及均等分裂发育途径等四种类型,并对这四种途径进行了讨论。

The nucleus vegetative in nature derived from unequal or equal division of the uninucleate pollen in rye anthers cultured in vitro develops into pollen embryoids or calli.The green haploid plantlets are differentiated successfully.The frequency of callus and embryoid formation may be efficiently increased when the spikes are pre- treated at 1—3℃ for 7 days before inoculation.According to the condition in which the multinueleate (free nuclei)and multi-cellular pollen grains become abortive,it is suggested that the formation of new walls between the dividing cells and the opportune rupture of the pollen exine are the two critical factors,which determine whether the embryoids and calli will be able to develop once the microspores are initiated.

离体培养黑麦花药,单核花粉可以通过不等分裂和均等分裂由营养性质的核发育成花粉胚状体或愈伤组织,并且最后形成了单倍体植株。接种前对穗子进行适当的低温处理,可以有效地提高胚状体和愈伤组织的生成率。根据多核和多细胞花粉的败育情况,认为新壁的形成和花粉外壁的适时破裂是已经启动分裂的小孢子能否发育成胚状体和愈伤组织的两个关键问题。
