Within this context, microseparation and in vitro culture of early zygotic embryos from polyembryony Citrus is very important because it makes possible the use of immature hybrid embryos and accelerates the sexual hybridization breeding in Citrus.

本研究初步建立了多胚性柑桔早期合子胚的显微分离、离体培养及合子苗的鉴定体系，成功显微分离了柑桔早期合子胚并通过离体培养再生植株，具体结果如下： 1、多胚性柑桔早期合子胚显微分离的最适时期为授粉后50—55d。

The yield and harvest times can be decided by regrowth ability of variety, sowing date and environmental conditions.

豌豆苗的采收次数和产量不仅与品种再生能力有关，和播种方式与生长条件也有密切的关系。

We studied the optimum medium and hormone combination of callus induction from cotyledons, subculture of callus, shoot regeneration from callus, shoot-extension induction, root induction and identified the chromosome number of the plantlet. The results showed that: MS+2,4-D 2.0mg/L+KT 0.5mg/L, MS＋2,4-D 2.5mg/L＋KT 0.5mg/L, MS+2,4-D 0+KT 1.0mg/L, MS+KT 0.5 mg/L and basal MS medium. One plantlet among twenty two was determined as a tetraploidy based on the plant morphology, observation of the leaf stoma and chromosome number of the root, other two plantlets represented morphological variation.

结果表明，诱导章丘大葱子叶产生愈伤组织、愈伤组织的继代培养、愈伤组织芽分化、芽点的伸长及诱导生根的最佳培养基及激素配比分别为：MS+2，4-D 2.0mg/L+KT 0.5mg/L、MS＋2，4-D 2.5mg/L＋KT 0.5mg/L、MS+2，4-D 0+KT 1.0mg/L、MS+KT 0.5mg/L和MS基本培养基；试管苗经驯化移栽后，共有22株成活，成活率为92%，对成活的再生植株进行形态学、叶片气孔及根尖染色体鉴定表明，共有3株发生变异，其中2株为外部形态上的变异，而另一株为染色体的加倍变异。

Diospyros kaki Thunb cv.Fuyu and Jiro are Japanese persimmon varieties. Dormant buds taken from persimmon trees, as in vitro explants materials, were set up successfully. New shoots were attained. Callus was induced and adventitious buds were differentiated from leaves and roots of tissue cultures; new shoots propagation and shoots rooting were studied in different basal medium added different hormones.

本研究以甜柿品种富有柿与次郎柿为材料，系统地研究了两品种的组培快繁、组培苗叶片和根段的不定芽再生、愈伤组织的诱导和不定芽的分化、不定根的诱导等技术，以期为柿果的转基因技术奠定基础，同时也为富有柿与次郎柿苗木的快速繁殖提供技术依据。

The in vitro regeneration techniques were established in Fortunella crassifolia and Citrus microcarpa.

建立了金弹和四季桔试管苗离体再生体系筛选出了适合金弹和四季桔种子萌发、离体繁殖、壮苗生根的一系列培养基。

Higher frepuency of germination , lower frequency of abnormal seedling , rapid growth and tender plantlets of Matthiola incana were obtained from the seeds cultured on MS basal medium without any hormone , which helps in inducing calli .

紫罗兰组织培养的研究(1)愈伤组织诱导及植株再生的研究：紫罗兰种子在不含任何激素的MS培养基上，发芽率高，畸形苗率低，幼苗生长快速，较鲜嫩，有利于愈伤组织的诱导。

Merismatic cells mainly derived from the inside of RBM, and belonged to ingenesis. With the ceaseless growth of small cell group, the outer layer cells apop tosis gradually. Finally the buds broke through RBM and became young plants.

芽的分化发生方式属内起源，随着小细胞团的不断生长，外层细胞逐渐凋亡，最终使分化的芽突出再生团块再生成苗。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.
