TETRAPLOIDS: Converted, in Cymbidiums In 1966 Donald Wimber presented a paper on the conversion of diploids into tetraploids by use of colchicine; many plants are now available. A78-1022; refer to AU80-109+They never revert to the diploid. OA75-214 0
TETRAPLOIDS: Cymbidiums A comparison with diploids: the tetraploid flower is bigger, the petals and sepals wider, so is the column; the shape is improved; the tissue of all parts is thicker and color is thereby intensified; better reflection of light results from heavier substance; spikes and stems are heavier and stronger; flowers have longer life on or off the stem, with or without water; they suffer less damage from handling and shipping. OA78-23 0
TETRAPLOIDS: In Cymbidiums "4n's" have advantages and disadvantages for the orchid world; the colchicine-converted ones have caused a lot of confusion in the orchid world; refer to OR81-169They are the heaviest producers of long spikes of large blooms on quick-growing strong plants; flowers become thicker in tissue, with wider petals including lip and column; an illusion of greater size; racemes shorter and fatter cause a less attractive arrangement of flowers on them; fewer flowers per spike. OA79-8 0
TETRAPLOIDS: Meaning A clone in which the chromosome count is four times the haploid or standard number; generally indicated by 4n. AU78-47 0
