摘    要:在近二十几年,尤其是近十年由于离体培养技术的完善和进一步向精确的层次的发展,已使得许多种植物花序、花芽和单独花器官以及部分的花器官在体外成功地进行了培养和尝试,并且对花芽及花器官的离体发育有了更深入的认识。不同植物的花发育需要不同的植物生长调节剂以及它们的不同配比,并且不同植物在其花发育所需要的营养因子也存在着相当大的差异性。这种差异性又随植物器官及花发育的不同阶段而受到加大或缩小。通过对正常花及突变体花进行的离体培养实验研究已经对一些花器官发生过程中的调节程序有了新的了解。利用离体培养技术,包括刚发展起来的薄层细胞培养技术在阐明花发育的机理、形态建成的分子机制以及成花梯度的物质基础等问题上具有广阔的潜力。

关 键 词:离体培养  花序  花器官  植物生长调节剂  花发育  高等植物

Abstract:In the past more than twenty years, the floral buds and individualfloral organs of many plants have been cultured in vitro, from which many generalcouclusions have been drawn such as: There is large difference in the requirementof plant growth regulators and nutritional factors for flower development of diffe-rent plants; The difference varies with the different hormonal and nutritionalrequirements at various stages of organ and floral development. Experimental studieson normal and mutant flowers in vitro have provided insights into some of theregulatory processes in floral initiation and development; Recently-estabolished thin-layer cell culture technigue have also offered a precise and convenient method tobe applied to study the molecular mechanism of floral development and the matterbasis of flowering gradient. In the paper, the authors also pointed out some pro-blems existing now in this field, and the prospect, meanwhile stressing the potentialof using the in vitro culture techniques to investigate the problems in this field.
Keywords:In vitro culture  inflorescencs  floral organs  plant growth regulators  floral development  higher plants
