Abstract: In order to improve pollination fruit- set rate, shorten seed germination time and improve seed germination rate of Cymbidium goeringii varieties, the authors studied the pollination time, fruit-set rate, seed aseptic germination of self-bred and hybridized Cymbidium goeringii varieties. The optimal pollination time was 2 to 5 days after flower blooming. Fruit-set rate of self-bred varieties was only 33.3%, and fruit-set rate of hybridized varieties reached 100%. The fruit vertical and horizontal diameter growth showed“S”shape curve. Mature seed germination time was 281-296 days, but the germination time of non-mature seed growing 130 days after pollination was the shortest, only 96-99 days, and the germination rate was the highest. The suitable time of capsules harvested was about 130 days after pollination. This test method would cut the time from pollination to seed germination by 8 months, increase germination rate, save the cost, and improve the efficiency.
