The pollen plants were successfully grown from the embryoids and calli induced from pollen in anther culture.By doubling chromosomes,more homozygous diploids were obtained.The effect of Laser on induction of the embryoid from the pollen was also studied and the preliminary effective measures of shoot formation from embryoid were made to decrease mixoploid phenomena.No reduction of the pollen plant in vitality from embryoid and callus has been detected.

成功地通过胚状体及愈伤组织诱导成花粉植株,经染色体加倍已获得较多的纯合二倍体株系;同时研究了激光处理花药对诱导胚状体的影响;初步摸索出通过胚状体成苗能减少混倍现象。经胚状体和愈伤组织诱导的花粉植株未见到发生衰退的现象。

Of 19 cultivars of sweet peppers used for anther culture 16 of them gave rise to embryoids, but normal pollen embryoids were obtained only from two cultivars, i.e. "Square Head" and "Lu-tai" ,whereas the embryoids from o-ther cultivars could not develop normally.The basic medium(NTH) was supple-mented with 0.25mg/l NAA,lmg/l kinetin, 50 mg/1 nucleotide and 3% sucro-se.

Of 19 cultivars of sweet peppers used for anther culture 16 of them gave rise to embryoids, but normal pollen embryoids were obtained only from two cultivars, i.e. "Square Head" and "Lu-tai" ,whereas the embryoids from o-ther cultivars could not develop normally.The basic medium(NTH) was supple-mented with 0.25mg/l NAA,lmg/l kinetin, 50 mg/1 nucleotide and 3% sucro-se. The pollen embryoids were further developed into haploid plantlets(n= 12) after transfer to NTH medium supplemented with 0.lmg/1 IAA (or 0.00lmg/1 NAA) , 2-4mg/l kinetin, 4mg/l 6-BAP (or 10% fresh coconut milk).The frequency of embryoid induction varies with the cultivar. LOW concentrations of NAA are beneficial to embryoid formation but the optimum concentra-tion varies with the cultivar.

花药培养实验共用十九个甜椒品种,在十六个品种中曾获得胚状体,但由于多数胚状体不能正常发育,仅有“四方头”和“旅大”两个品种的花药在附加0.25毫克/升萘乙酸(NAA),1毫克/升激动素,50毫克/升单核苷酸的NT_H培养基(蔗糖3%)上产生了比较正常的花粉胚状体。将其转移到含有0.1毫克/升吲哚乙酸(或0.001毫克/升NAA),2─4毫克/升激动素,4毫克/升6—苄基嘌呤(或10%椰子乳)的NT_H培养基上,花粉胚状体进一步发育为单培体植株(n=12)。花粉胚状体的诱导率因品种而异。低浓度的萘乙酸有利于胚状体的形成,但是不同品种在形成花粉胚时所需要的萘乙酸浓度不同,将获得的花粉植株用0.2%的秋水仙碱液进行处理24小时,其中染色体获得加倍的植株,能开花结果。

The proper time for anther culture of tomato plant in vitro is uninucleate Stage. A lot of plantlets were induced from callus. Multicellular aggregatesand-2-4nucleate pollen grains were observed through squashing of anthers. The chromo-some number of the root tip of the pollen plants was found to be n= 12.

我们自1975年开始番茄(Lycopeisicvm esculenetum Mill)花药离体培养的研究。大量的工作证明番茄花药离体培养的最适合时期为单核期。供试验的品种均可诱导产生愈伤组织。诱导产生愈伤组织的培养基为MS+激动素1-2毫克/升+萘乙酸0.5-1毫克/升+3%蔗糖。当培养基内加入10%的椰乳时能明显地提高诱导频率。诱导愈伤组织分化的培养基为MS+6-苄基腺嘌呤2毫克/升+吲哚乙酸0.2毫克/升+2%蔗糖。已从大叶早粉、满丝、北京早红×402番茄品种的愈伤组织中诱导产生出大量花粉植株。诱导生根的培养基为H+吲哚丁酸0.5毫克/升+2%蔗糖或MS+吲哚乙酸0.2毫克/升+2%蔗糖。培养适宜的温度条件为25-27℃。 通过花药压片的显微观察,已看到2-4个细胞的花粉粒和多细胞团。诱导出的植株经根尖压片检查,染色体n=12,证明是来源于花粉的单倍体植株。
