[Aroid-l] Re: variegata aroids

From: "Agoston Janos" <agoston.janos at citromail.hu> on 2006.12.21 at 19:11:59(14980) Ok, but can we stabilize variegation? Are there any variegated tuberous or rhizomatous aroids? ----- Original Message ----- +More From: Michael Marcotrigiano To: aroid-l@gizmoworks.com Sent: Thursday, December 21, 2006 5:36 PM Subject: Re: [Aroid-l] variegata aroids + a lots of questions +contacts Variegation can be induced with nasty mutagens like Nitrosomethyl urea.I would not recommend doing so unless you have a compelling reason andexperience using such chemicals. There are a few viruses that causevariegation but most of them harm the plant and make them useless. Thebig exception is some forms of the mallow family Abutilon.Micropropagation can induce many variations and some of the variegatedforms of plants do come from micropropagation but it appears to be lowfrequency so finding them involves a great deal of chance and or largecommercial production where tens of thousands of plants are produced andgrown out. Spontaneous mutations of plastids can occur and are seen inseedlings on occasion and this is the source of some variegated plants.So the answer is not simple._______________________________Michael Marcotrigiano, Ph.DDirector of the Botanic Garden and Professor of Biological SciencesSmith College, Lyman Conservatory, College LaneNorthampton, MA 01063email: mmarcotr@smith.eduvoice: 413-585-2741; fax: 413-585-2744www.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 howvariegation starts. Are there some viruses or chemicals which can inducevariegation? Can occure variegation by micropropagation? How often?The second question would be: How to take care of Anubias andCryptocoryne. They are sold as aquatic plants, but my Anubias has grownout from the tank. Do they need a dry period or what? What are therequirements 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.huviraghagymasz@davidnet.hucontact@hagymarium.hu - not too often checked, but weeklyszaki@hagymarium.hu - - not too often checked, but weeklyAnd you can call me on skype: skype:viraghagymasz?callBye,Jani, Z5a_______________________________________________Aroid-l mailing listAroid-l@gizmoworks.comhttp://www.gizmoworks.com/mailman/listinfo/aroid-l _______________________________________________ Aroid-l mailing list Aroid-l@gizmoworks.com http://www.gizmoworks.com/mailman/listinfo/aroid-l
