【Abstract】 An efficient and simple method of high frequency protocorm regeneration from pedicel axillary bud of Phalaenopsis is described. Pedicel axillary buds were cultured on Murashige and Skoog’s basal medium (MS) with combinations of 6-benzylaminopurine (BA) (2-3 mg/L) and α -naphthaleneacetic acid (NAA) (0.1-0.5 mg/L). Medium supplemented with 3 mg/L BA in combination with 0.1 mg/LNAA produced the best response in protocorm occurrence(80%) without addition of any organic material. On subculture to the same medium, protocorm produced the shoots within 4 weeks of culture and well developing shoots were obtained separately. 40% of developed shoots produced root on medium supplemented with 0.1 mg/L IAA and the plants were transferred to moss for growth. Because of the simplicity for culture medium ingredient, it is a reliable protocol for plant regeneration of Phalaenopsis factory production in developing country and is also useful to genetic improvement programs.更多还原
