I was wondering this for a while now and especially since Patrick's post on Reine Violettes. Most of my Bourbons and Hyb. Musks were from Roses of Yesterday and Today. They have been good plants in the past, but are not as vigorous as they once were. I got a pink pillar from them and when I had to move it, it had made its own roots so I cut off the old Dr. Huey roots which were now a thick woody knob. The rose foliage immediately showed the mosaic pattern even though I had never seen it on the leaves when it was on the Huey roots in the old location. Now it is SP'd. Are the roses from Antique Rose Emporium on Huey rootstock or own root? I need to replace a number of OGR's and was thinking of buying there.

For someone in zone 10, there probably is very little chance of mosaic type virus spread as the rose's immune system is effective at high temperatures. ----------------------------------------- Concerning Davis's indexed roses. Davis has recently published a paper where they announced that they found an aphid spread virus in their indexed rose plantings (see page 511): "In this test, RSDaV was detected in many different rose species and cultivars from the Foundation Rose Collection at FPS. In all, 129 plants in this collection were tested, and 77 were positive for RSDaV. Some of the hybrid rose cultivars tested positive for RSDaV included Queen Elizabeth, China Doll, Heirloom, Lowell Thomas, Jack Frost, New Dawn, Uncle Joe, Bridal White, Butterscotch, and Cynthia. It is interesting that the virus was detected in more than 69 plants in two rows (total number of plants in these rows was 89) of the collection which were planted in the mid 1990s. In all, 162 samples of R. multiflora from the virusindexing rose blocks also were assayed in the spring and RSDaV was found in 94 plants. The majority of RT-PCR-positive R. multiflora plants were symptomatic. Another 40 additional plants from the same virus-indexing blocks were tested in the summer and 6 were positive."

I am interested in research papers that investigate the temperature dependence to a plant's ability to fight off virus infections. The full paper accessed through the link below states: "Development of symptoms following inoculation of N. tabacum (��Petite Gerard��) with ToRSV was influenced by temperature. At 34�aC, visual symptoms did not develop on the inoculated leaves or on upper, noninoculated leaves and neither viral RNA nor viral-derived siRNAs were detected in samples collected randomly (data not shown). At lower temperatures, lesions developed on the inoculated leaves 2 to 3 days postinoculation (dpi). At 21�aC, lesions were clearly defined and necrotic (Fig. 1A, panel 1)." This paper titled (Salicylic Acid-Dependent Restriction of Tomato ringspot virus Spread in Tobacco Is Accompanied by a Hypersensitive Response, Local RNA Silencing, and Moderate Systemic Resistance) ties together the "RNA silencing" type immune system response with the "Salicylic Acid" type immune response. The following is a key quote from the abstract: "Lesion size and viral systemic spread were reduced with SA pretreatment but enhanced in NahG transgenic lines deficient in SA accumulation, suggesting that SA-dependent mechanisms play a key role in limiting ToRSV spread in tobacco." In the full paper the following results should be of interest in this thread: "The percentage of plants that became systemically infected was also significantly reduced in SA-treated plants (9% �b 6 in SAtreated plants versus 49% �b 15 in control plants; three independent experiments; P Here is a link that might be useful: link for above, full paper is free

Hi Carol, I do it in Picasa, just choose however many pictures you want 2, 4 or more and then send it to collage..then you arrange your pictures and just enlarge them to fit the collage box..so simple even I can do it!!..no extra software needed. Basically, I love Picasa except for the nasty little habit it has of when you send pictures to your albums they normally go to the end of the album..sometimes it makes a mistake and they end up somewhere in the middle of the albums and throws off the sequence and that is what messes up my pictures sometimes in these posts.. I go back to check and there is a different picture there..very frustrating since you can't at that time fix it..if you move one, they all get messes up... But since I have about 7,000 pictures, (not all hippies) I'm not going to change at this point..it doesn't happen all that often... You can also write text on the picture, very simple... Donna
