Growth and blooming in 36 months was achieved from phalaenopsis with thousands of vigorously growing plants but Benzyl-amino-purine (BAP) greatly increases the percentage of sports which are sold to the public; unsuspecting? A83-1150

Mericlones Comments
MERICLONES: Are They All Alike? This scientific claim may not hold true in practice; perhaps natural improved varieties are possible during tissue multiplication; it may account for some of those claimed to be products of colchicine treatment. AU79-140 0
MERICLONES: Cattleyas Have Bloomed Only 50% Recovery from poor culture sometimes takes a long time even for meristem cattleyas; do not over-water; 18-18-18 fertilizer is satisfactory for culture in rock. A75-35 0
MERICLONES: Clonal Aberrations From one piece of tissue, after about 25,000 plantlets have been proliferated the aberration rate becomes unacceptibly high, and almost invariably in the direction of poorer quality. AU79-197 0
MERICLONES: Grading for Quality This is necessary because there are differences and the unwary buyer can be stung; they should be graded according to whether they are original material or secondary productions from the tissue stock; growers usually do not release original material; but buyers of unthrifty third-generation material are usually dissatiafied; (that's why those wonderful cymbidium seedlings we got from Weston and those fabulous cattleyas we got from Mata Toa all had to be junked?) AU81-250 0
MERICLONES: Mutations Not all mericlones are the same and variants appear proportional to the number produced and most of them are disappointing although oeassionally one is worthwhile and different and should not carry the original, usually awarded, variational or clonal name. A83-1294 0
MERICLONES: Numbers of Explants Commercial laboratories usually produce only 5000 explants before mericloning the mother plant again, but if the mother plant is known to be stable the production can rise to 20,000. Au81-165; Hort. revs. 1983-296 0
MERICLONES: Of Cymbidiums for Improved Varieties A list of 18 mericlones which have shown mutations quite different from the originals, and without the use of colchicine; they show bigger flowers of the same color, more distinctive markings,etc.; but with shorter spikes, fewer flowers, altered dates of flowering and different growth habit. AU79-140 0
MERICLONES: Value as Stud Plants Meristem-propagated plants have the same chromosome and breeding characteristics as normal plants. A67-233 0
MERICLONES: Why They Differ When the meristematic plant tissue is cut, some cells are cut through and most of those die but a few recover and may produce abnormal incomplete plantlets; as orchids are complex, more can go wrong. OIE87Jy-6 0
