RE: Ulearum donburnsii
From: "Wilbert Hetterscheid" hetter at worldonline.nl> on 2002.05.15 at 19:33:04(8800)|
The hybrid product is the result of an autoplyploidisation event in the sex
cells of bulbifer and that followed by a reduction in the cross, leading to
a tertraploid hybrid result........ But maybe I haven't made myself clear. I
am going to pubslish it EARLY APRIL 2003........
As for a serious answer: bulbifer will usually not produce a leaf in the
same season when it is allowed seed set.
