Abstract

The influence of different reagents and dark treatment time on initial seed germination time and germination rate of Cymbidium goeringii were studied，and the seed germination process was observed. Under aseptic conditions，the seeds treated with chemical NaOH and NaClO were placed in dark culture for 0，30，60，90，120，150，and 180 d cultivation followed by after dark culture then further culture for light. Results showed that seeds did not germinate with only dark or no dark treatments. For seed germination rate，the NaOH and NaClO treatments had a strong impact with the NaOH treatment being as high as 79.2%. For seed germination there was an interaction with reagent treatment and dark incubation time. Also，seeds with 30 d dark treatment began to germinate after about 35 d of light cultivation，and their initial germination time was shortest. The germination process of C. goeringii included the following states：original un-germinated seeds，swelling of the embryo，original bulb，green growth，and extension of the rhizome from the original bulb. Thus，this experiment showed that darkness and light were necessary for initial seed germination.［Ch，3 fig. 1 tab. 16 ref.］
