variegata aroids + a lots of questions + contacts

From: "Michael Marcotrigiano" <mmarcotr at email.smith.edu> on 2006.12.21 at 16:36:47(14974) Variegation can be induced with nasty mutagens like Nitrosomethyl urea. I would not recommend doing so unless you have a compelling reason and experience using such chemicals. There are a few viruses that cause variegation but most of them harm the plant and make them useless. The big exception is some forms of the mallow family Abutilon. Micropropagation can induce many variations and some of the variegated forms of plants do come from micropropagation but it appears to be low frequency so finding them involves a great deal of chance and or large commercial production where tens of thousands of plants are produced and grown out. Spontaneous mutations of plastids can occur and are seen in seedlings on occasion and this is the source of some variegated plants. So the answer is not simple. +More _______________________________ Michael Marcotrigiano, Ph.D Director of the Botanic Garden and Professor of Biological Sciences Smith College, Lyman Conservatory, College Lane Northampton, MA 01063 email: mmarcotr@smith.edu voice: 413-585-2741; fax: 413-585-2744 www.smith.edu/garden ----------------------------------------------------------------------------------- Trees are poems that earth writes upon the sky, We fell them down and turn them into paper, That we may record our emptiness. ~ Kahlil Gibran >>> "Agoston Janos" 12/21/06 10:39 AM >>> Dear All, Can somebody help me with variegated Araceae? Because I do not know how variegation starts. Are there some viruses or chemicals which can induce variegation? Can occure variegation by micropropagation? How often? The second question would be: How to take care of Anubias and Cryptocoryne. They are sold as aquatic plants, but my Anubias has grown out from the tank. Do they need a dry period or what? What are the requirements of Lysichitons. I have allready killed 5 pcs. Sorry for the many questions, but I still not received the Aroid book, and thank you for your help in advance! ----------------------------------------- I have new mail addresses. agoston.janos@citromail.hu viraghagymasz@davidnet.hu contact@hagymarium.hu - not too often checked, but weekly szaki@hagymarium.hu - - not too often checked, but weekly And you can call me on skype: skype:viraghagymasz?call Bye, Jani, Z5a _______________________________________________ Aroid-l mailing list Aroid-l@gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l
