Abstract

|
|
Self-pollinated seeds obtained from 7 species of temperate Cymbidium arid cross-pollinated seeds between these species were subjected to aseptic cultures for the micro propagation as well as for the asymbiotic germination. Number of days required for seed maturation after pollination ranged from 10 to 13 months and seed germination in vitro after culture from 145 to 294 days.
The Geumrungbyon (Cym. pumilum) and hybrid between Cym. faberi `Daeilpum´ and unknown western Cymbidium developed protocorm-like bodies and formed organs easily. The addition of l0㎎/ℓ BA to rhizome cultures was effective in organogenesis but not in growth of rhizomes, while lower concentration of 1㎎/ℓ BA the growth of shoots and rhizomes formed. The effects of casein hydrolyzates, tomato juice, and potato homogenates were also examined in this study.
A few novelties such as albino rhizomes and plants, and chimeric plants with white-stripped leaf blades were observed.
