Consider for a moment the expense of setting up a tissue culture laboratory, above that of, say, the average hobbyist with a cut-up Rubbermaid« tub; a collection of baby food bottles; a spray-bottle of bleach; and a Sacred Heart of Jesus votive candle. Consider then the expense involved in primary research and the myriad and often costly failures; and the very-western concept of intellectual property, which is seen as somehow legitimate in every other realm of human endeavor.
As an aside, Nepenthes has been tissue cultured for decades; yet poaching is, arguably, as rampant as it always has been; and black markets still exist throughout Asia.
Consider, also, how small the market is for carnivorous plants, which is, admittedly, far greater than when I began; but is still insignificant, when compared to orchid cultivation. Growers would naturally wish to maximize their profit in so small a venue.
That said, I had moderate success with isolating the growing tip of Nepenthes hamata a few years back, for a Japanese client; and that involved the preparation of a carefully-cleaned 3 cm or so section of plant. At the time, I had ready access to fungicides no longer legal within the US, and to perhaps a dozen or more antibiotics and antimycotics at my disposal. It took serial re-plating to obtain a "clean culture;" but it can be done. The standard media was 1:3 MS with 8.8 ÁM 6-BAP; but meristematic tissue is a real coin toss, since you cannot be sure which growth phase the tissue is in when you make the attempt to establish it. Nepenthes also has a reputation for being "woody;" and there are some other medias, namely WPM, where growers have had some success.
There are many papers involving in vitro culture of Nepenthes online. A twenty minute search should find a few. Still others are on costly academic databases; but abstracts are generally available. Check also the ICPS database for TC cultivation and the www.flytrapcare.com tissue culture forum for sources. There have been some threads within the last year or two . . .
Thank you, I will look into those forums and see what I can find. I appreciate the help quite a bit.
