Am I confused are is HH the guys with the gift shop in Kona? HH has a reputation I think (the people, not the coffee) that has a few dents in it, but then again so does everyone in Kona :-0 I jest, but as far as the Liberica graft, it is common in many places (where they can afford to do it on a mass scale) and was researched extensible in Colombia at Cenicafe. I was there and saw the liberica seedlings in the nursery for this purpose. The idea is partly that grafting to robusta might have cup implications, not immediately, but if plants are derived from such a graft. Not being a geneticist, I am not exactly sure if hybridization / mutation through grafting is a reality, or just a franken-myth. Can somebody on the list answer that question? Tom Mike, I hope Tom offers a Heavenly Hawaiin KONA someday.

I hope that makes sense but it was interpreted as support for the argument for hybridization through grafting. I believe it involved the petunia. This was from lectures in my undergraduate biology classes at Oklahoma State back in 1967. This is not my area but I would guess that some of the more recent discoveries that led to using viruses to transmit DNA across species could lead to a hypothesis that the male fertility could have been transmitted through viral transmission of DNA from the root stock to the flowering tissue. pecan jim --Apple-Mail-10--907738512 Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset O-8859-1 On Oct 11, 2007, = at 6:29 PM, Tom & Maria - Sweet Maria's Coffee wrote:
The nutrients and other stuff supplied by the rootstock to the branches could easily vary with the rootstock and have a strong effect on the coffee without any changes in DNA. That doesn't mean there aren't genetic changes. An anecdote: The piece of land I grew up on had been owned by someone who obviously loved fruit trees. Among the others, there were a couple of lemon trees with orange branches grafted on. The oranges were much more tart than typical oranges. Too bad they didn't complete the experiment by grafting lemon branches onto an orange tree. Clay
Couldn't resist putting in my two cents worth. A rootstock permitted to develop branches, leaves, fruit and seed from its own tissue.....those things should display characteristics of the rootstock. Its function is usually considered to be basically mechanical. Grafted material above the rootstock SHOULD reflect characteristics of the graft only. I've seen pecan grafted on hickory rootstock and the nuts tasted like......pecans, not hickorynuts. BUT certain scion/rootstock combinations in apples produce unusual effects...dwarfing, altered fruiting patterns, etc., so I suppose it is conceivable that the rootstock could have some effect on the fruit of the coffee plant and ultimately the taste of the coffee. Its just very difficult to imagine how. Josh On 10/11/07, Clay Spence wrote: <Snip>
I have purchased HH and TOF coffee a few times and have realized the = benefit of Tom's careful cupping and reviews. They harvest their coffee the same time of the year as other Kona growers, with some variation I suppose = based on altitude. But they do sell their coffee year round. Some I've had was good, fresh Kona and others seemed to have lost the flavor highlights = and richness that fade with age. I am also sure the flavor and quality vary = from harvest to harvest due to weather. I decided my next HH/TOF purchase = would probably be when Tom decides the lot he buys is good enough to offer on = the SM site. Terry

Tom, I'm no geneticist either but I watch one on tv. My grandpa many years back planted seeds from a pear and got a hawthorne... or something like that. It flowered but never made a fruit if I got the story straight. So strange things can come out of graftings.
