Orchidaceae is the largest and most diverse family of the flowering plants,consisting of 35,000 species under 800 genera (Singh et al.,2007).Due to poor hybridization barrier,more than 1,50,000 hybrids already have been produced and registered,many of which are multigeneric (Sheehan,1980; Tsavkelova et al.,2001).Exquisite and perpetual flower of orchids made them doyen among ornamentals.Evident by recent increases in world floriculture trade,orchids became the second most popular cut flowers as well as potted floriculture crop with wholesale prices estimated at $126 million (USDA,2008).Due to continuous destruction of natural habitats,unauthorized trade and ruthless collection by orchid lovers,many orchid species in nature are disappearing at an alarming rate.Furthermore,their high commercial demand has undoubtedly led to an increased emphasis on mass propagation and conservation of important orchids (Stanberg and Kane,1998).Major obstacles for mass propagation of economically important orchids for commercial purposes as well as conservation are:(1) unavailability of efficient and reliable protocols for seed germination,(2) obligate mycorrhizal association for natural seed germination,3) a clear understanding of early seedling growth and development and,4) high mortality of seedlings during transplantation.Ever since the development of a method for asymbiotic germination of orchid seeds by Knudson (1922),the techniques have been used routinely for large scale propagation of a number of orchid species and their hybrids (Arditti and Earnst,1984; Buyun et al.,2004; Shimura and Koda,2005; Yamazaki and Miyoshi,2006; Stewart and Kane,2006) but a very few studies critically investigated the peculiarities of seed germination and protocorm development.Keeping this in mind,the present research programme was under taken with a view to i) develop efficient protocol for in vitro asymbiotic germination of seeds,ii) study the effects of plant growth regulators (PGRs),activated charcoal and peptone on seed germination and growth of seedlings,and iii) investigate the mode of morphogenesis of embryo during development of protocorm in Epidendrum ibaguense Kunth.a floriculturally important orchid.

兰科植物是开花植物中最大且是种类最多变的家族,它包括800多个属中的大约35000个种.由于杂交障碍极小,超过150000种的杂交品种被生产和命名,它们中的很多是多代杂交（产生的）.精致的、四季常开的特性使兰花成为观赏植物的“前辈”.从最近的世界花卉贸易增长值中明确体现,兰花成为第二大最受欢迎的批价达到1.26亿的插花与盆栽作物.由于（兰花的）自然栖息地被持续地破坏,兰花爱好者的非法贸易与残酷采集,许多兰花的种类以惊人的速度消失着.此外,它们的高商业需求毋庸置疑地进一步强调了对兰花的大量繁殖和保护的重要性.为了保护兰花及其重要的商业目的的大量繁殖面临的主要障碍是：1.收效甚微的关于种子萌发高效可靠的方案；2.（落后的）种子与真菌共生技术；3.清楚地了解早期幼苗的生长和发育；4.高死亡率的幼苗移植.从克努森开发出一种非共生的兰花种子萌发的方法之后,这种技术便常用于大规模兰花品种及其杂交的繁殖.但极少数研究批判性研究了种子萌发的特点与圆球茎的发育.记住这一点,目前的研究项目用这样一个视角：1.开发高效的种子体外非共生萌发方案；2.研究植物生长调节剂、活性炭、蛋白胨对种子萌发和幼苗生长的影响；3在攀缘兰——一种重要的变异兰花——圆球茎的发育过程中研究胚胎形态发生的模式.
