I have seen color break in orchid flowers caused by
virus, as well as soft brown spotting on white flowers and a very short life
span, but I haven't really identified distortion on any of my virused
plants. Below is a picture gallery that I am building that shows some of
the symptoms I've seem. I have seen: 1) color break, a certain indicator
of virus and looks like water marks. 2) black spots, generally larger than
fungal spot, and sunken. In particular is the tendency for the spots to
align along a vein. 3) crooked growth. I am reminded of the rhyme or
story of 'The crooked man that walked the crocked mile...". 3) large
lighter spots that are outlined in black.and other flower like patterns.
4) odd spots of chlorophyll loss that are very small and run along the leaf
veins a very short distance. If I think of any others shortly, I will add
them in a further email. I have tested about 50 plants so far, some
of the worst looking, and have about a 2/3s virused rate. I just sent out
another 125 samples for testing, so the pbase site will be updated as soon as I
get results. Cynthia, Prescott, AZ
