All of them showed no harmful effects for the growth of 7-days-old mungbean sprouts. The inoculation of OMF to Anoectochilus formosanus Hayata and Haemaria discolor var. dawsoniana all showed significant enhancement for seed germination and seedling growth in vitro as well as those in vivo. In vitro, Hyponex No. 1 or 3 with either 20 or 30 g/l of sucrose in growth medium had higher germination rate for Haemaria discolor. For Anoectochilus formosanus. Activated carbon enhanced the expression of apical dominance but inhibited the formation of lateral buds. Also there was no significant effect for the presence of coconut water in the growth medium. It was known previously that the optimum temperature for the growth of Anoectochilus formosanus was 20/15 ℃ (day/night temperature) , and the results showed that for Haemaria discolor , 30/25 ℃was optimum. Many fruit capsules for both plants were collected by hand pollination, and the seeds will be useful materials for next years researchapplication/pdf37027 bytesapplication/pdfzh-TW國立臺灣大學園藝學系暨研究所彩葉蘭金線連蘭菌Haemaria discolor vardawsonianaAnoectochilus formosanus Hayataorchid mycorrhizalreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/18193/1/882313B002060.pdf
