This application discloses a method for directly cultivating seedlings from the
germination of *
Cymbidium goeringii* seeds in Yunnan. The method includes the following steps:
sowing *
Cymbidium goeringii* seeds on a modified culture medium, followed by 6 months of constant temperature cultivation at 25℃ to obtain small pseudobulbs suitable for direct
transplanting. This method is simple to operate; seeds begin to germinate and turn green 20 days after
sowing, begin to grow leaves after 45 days, begin to root after 60 days, and show significant
root growth after 90 days. The pseudobulbs also enlarge synchronously. After 6 months, the plants naturally shed their leaves in the
tissue culture bottle, and the pseudobulbs can be transplanted to the field for
acclimatization and cultivation. This method eliminates the need to change the culture medium, removes the manual transfer step in the
tissue culture process, and solves the problems of yellowing, difficult rooting, and high
contamination rates after transfer of
tissue culture seedlings. Furthermore, the plants naturally shed their leaves in the tissue culture
bottle, directly obtaining small pseudobulbs without hardening off, and improving the transplant
survival rate, which is beneficial for the large-scale cultivation of *
Cymbidium goeringii*.
