[IBC] Diseases
Have you ever noticed? Conditions that are considered horrible diseases in
animals and humans are desirable traits in trees: Scleroderma, elephantiasis, vitiligo, torticollis, dwarfism, psoriasis, etc. Remember albinism in plants means white flowers; albino animals & people have white hair & pink eyes. As far as I know, there is no equivalent in animals of variegated foliage, since all parts of the body must have circulation of red blood cells.

Iris ------------------ I am not sure about that, Iris. Hair on dogs and on people can be quite variegated. Is it possibly foliage? Hm - well, I guess not - hair doesn't fill the same job requirements . . . that may be relevant . . . Now, why does this occupy my mind - ach!

Lynn: Then there is the condition called vitiligo which could be
considered a type of dermal variegation for humans. Alan Walker http://bonsai-bci.com http://LCBSBonsai.org -----Original Message----- From: Have you ever noticed?

Then there is the condition called vitiligo which could be considered a type
of dermal variegation for humans. As I explained already, vitiligo is not the human equivalent of variegated foliage. The white patches in vitiligo are the absence of melanin pigment. The entire skin has a blood supply, otherwise gangrene would occur. Vitiligo can be compared to a plant which has patches of red or purple on green leaves, like some coleus, not on white and green variegation. In variegated foliage, the venetion throughout the leaf is normal. The palisade layer, which contains the chloroplasts, is missing, or some of the chloroplasts are lacking in chlorophyll. The green parts of the leaf perform photosynthesis and send nutrients to the white part. But this is similar to supporting flowers, so variegated plants tend to be weaker or slower growing than all green ones. Iris, Central NY, Zone 5a, Sunset Zone 40 "If we see light at the end of the tunnel, It's the light of the oncoming train." Robert Lowell (1917-1977) |
