Phal. Leuddemania won't flower
About two years ago I bought an N.B.S. Phal. Leuddemania “Arlington”
from Parkside, it arrived in good shape and has grown well. Last year it threw a flower stalk which is still there and very much alive but did not produce any flowers. This year it threw two more flower stalks that are both doing well. All three stalks show what look like tiny buds but do nothing more. The plant is growing on a windowsill with natural light. Five other phals next to it are growing well and flowering in season. Any ideas on getting it to bloom? Thanks in advance |
Probably apropos of nothing I came across many of Dr Wang's articles online.
He notes higher nighttime temps than the conventional wisdom would allow. http://primera.tamu.edu/orchids/orchids.htm Whether this applies to species phals I have no idea, but its food for thought.

I had a variety called 'pulchra' and found that mine needed a bit more light
than the average phal, and as was suggested, warmer night temps. Dont give up on it. It will bloom when you get fed up with it and threaten to throw it out. |

I have a Phal lueddemanniana pulchra subvar alba

Have you ever selfed that plant Mick?

Dustin,
Yes. I selfed it 4 years ago, but owing to a pH meter failure I accidentally burned up the offspring with a "hot" agar mix. One keiki from this plant sold for $2,000 two years ago to a collector in Taiwan. The main plant is spiking again so I will be trying another selfing soon. This pure white flower just takes my breath away... it is really magnificent. Mick -------------------------------- "Dustin " wrote in message ... Have you ever selfed that plant Mick?

Wow, 2k for a keiki, I bet you were a happy camper. Why not clone it?

hello everyone!
Sorry, might be a dumb question but... what is the difference between selfing and cloning? My understanding is that selfing is pollinating the plant with it`s pollen, that way, you get seeds and can go flasking. Cloning is taking cells from a part of the plant ang grow it in flask! Am I right? If so, what are the difference? Thanks Claude "Dustin " wrote in message ... | Wow, 2k for a keiki, I bet you were a happy camper.

Hi Claude,
Not a dumb question. To understand the difference you have to understand what is going on with the selfing. Genetically plants have pairs of chromosomes. In the sex process, eggs and pollen are made with one of the chromosomes from the pair. The two join creating a plant with a pair of chromosomes (one from the egg and one from the pollen). If the plant we wish to self has the following chromosome pair Xx, the resulting offspring will have Xx, XX, and xx for chromosome pairs. The probability that a selfing will have the same chromosome pair as the mother is .5. A Phalaenopsis has 38 pairs of chromosomes. Thus the probability that a selfing will have the exact same genetic make up as the mom is .5 to the 38 power which is something like 1 in 274 billion.

Am I right? If so, what are the difference? Not a dumb question, but there is a difference: In selfing there is only one parent but it's still sexual reproduction. The plant has two copies of each gene which may be different (alleles). Each pollen grain and each egg contain one copy of each gene and the choice is independent each time, so you get different combinations when they are put back together in selfing. Each time you self, for each gene, there is a chance that the offspring will get two copies of the same allele (homozygosity). This means that for that gene there is nothing to vary when that offspring is selfed (it will 'breed true' for whatever characteristics that gene determines). If you self repeatedly, you'll end up with a plant that is homozygous for all genes, and if you self that its offspring will effectively be clones. They will also be fully inbred (which is the same thing as fully homozygous) which is something vegetative clones aren't necessarily. Leo |

As an aside, it's worth mentioning that many flowering plants, perhaps
as many as 50% or so of all species, are polyploid. That is, they carry more than two copies of each chromosome and therefore more than two alleles of each gene. Polyploidy is often a good thing in that it may confer larger size and more robustness. It is sought in some orchid breeding by using agents such as colchicine that inhibit proper chromosome behavior during cell division. Jim |
Thanks everyone!
