Re: [Aroid-l] Arum

From: "Agoston Janos" <agoston.janos at citromail.hu> on 2007.05.04 at 09:37:14(15627) Yes, but how can a tetraploid plant set seeds?! If meiosis occures the chromosomes cannot be "halved" correctly by pulling threads, so I think it could not bear living pollen or oocytes, but my plants sets seeds yearly. +More Is this means that there are also diploids?! |:-/ Or Mr. zonneveld got only tetraploids... ----- Original Message ----- From: Tony Avent To: Aroid - L group Sent: Thursday, May 03, 2007 2:16 PM Subject: [Aroid-l] [Fwd: [pbs] Arum] Dear Arum Growers:I thought I would copy this post from the Pacific Bulb list about arum...very interesting.-------- Original Message --------Subject: [pbs] ArumDate: Thu, 3 May 2007 13:15:05 +0200From: B.J.M. Zonneveld Reply-To: Pacific Bulb Society To: I am a bit late to react on the Arum subject However you will forgive meknowing I was looking for tulips in Kazachstan etc. All Arum italicum,about 10 clones, I have measured the amount of nuclear DNA from are sofar, ranging from Greece via Italy and France to Portugal and theCanarian islands are hexaploid. Arum concineum is diploid and Arummaculatum tetraploid as far as I measured them. Peculiar is that twoarums from greece, one with whitish veins, the other more spotted butwith dark purple stems and flowers flowered fro me in April This seemsvery early for A italicum I wondering if they might do so the next year.I am still looking for a fresh leaf ( or seeds) of the more rarespecies to measure..._______________________________________________pbs mailing listpbs@lists.ibiblio.orghttp://lists.ibiblio.org/mailman/listinfo/pbs-- Tony AventPlant Delights Nursery @Juniper Level Botanic Garden9241 Sauls RoadRaleigh, North Carolina 27603 USAMinimum Winter Temps 0-5 FMaximum Summer Temps 95-105FUSDA Hardiness Zone 7bemail tony@plantdelights.comwebsite http://www.plantdelights.comphone 919 772-4794fax 919 772-4752"I consider every plant hardy until I have killed it myself...at least three times" - Avent_______________________________________________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
