This has been a source of much interest to me. Red cymbidiums are notoriously poor growers, although some of the more recent hybrids seem to be better in this regard. A while ago, i saw two siblings from a Maudiae-type paph cross, one of which was albinistic, and the other vinicolor. It was surprising how much smaller the vinicolor was than the albino. It became obvious to me that the production of anthocyanins must be very resource-expensive for the plant. This "wanton" use of energy and chemical precursors must leave plants depleted and unable to grow or thrive or protect themselves against infections as well as low-anthocyanin plants would. Anybody have any ideas in this field? regards, greig russell "Valhalla", Osborne Lane, 7975 KOMMETJIE, Western Cape. (021) 783 3962 http://www.geocities.com/pennypoint9/ http://tygerorchids.itgo.com
