I hadn't tried accessing on line jounals with my membeship card but perhaps they could let me know if that is possible. The original journal will sell a full copy of the journal article for $30 USA$, but that would buy two new SDB  new introduction from some breeders, at least.


Flirting with one of the student assistants works for me sometimes..... long as I stay on the phone and don't appear in person. <laughin'>

I've compared the cost of attending meetings/conventions vs. how many irises I could purchase for those dollars more than a few times. Other times I've compared steak or hamberger vs. irises. In both cases, more often than not, irises win the argument.

The picture you provided was most helpful. As a point in passin', I do not believe the tranfer of such for research purposes is prohibited. Certainly I'm not expert on the subject.

I've examined the cell structure of the outer layer of albicans. I cannot with certainty say it is one layer thick but think so. The problem I incounter is the focal plane of the microscope does not allow depth examination.

I found it best to examine a specimen that contained a full petal thickness and the the petal surface tissue in question. I could then follow the edge of the tissue separation from its inital start to its widest point and make visual comparisons between the cell structures on both sides of the separation line.

I've not found my blank slides yet. I viewed the above on a lucite lid from a string tag box. The scope is designed to hold specimens on thicker material but this worked pretty good and was only a bit frustrating. A slide mounting of the specimen will allow viewing without so much focusing and refocusing of the instrument. Examination at higher powers will also be more practical. For now I only viewed at successfully at lower powers.

An update:
I've managed to find a single blank slide. Clear cellophane tape provides the best method for securing the specimens to the slides. Exciting at first because of being able to examine the cell structure, albicans became boring over time. No tints present other than gray. Examinations became more entertaining viewing a specimens from an aril bred. There was a whole new world of color in the falls of Zizha. I detected no AVI.

The cell shape was of course different between the irises and the lisantus photo you sent. Otherwise they looked pretty much the same except there were no spherical shaped inclusions in the irises. I will continue the search as more irises bloom.
