Eine Frage an die Experten,

habe heute bei meiner Golden Sword bemerkt, dass aus einem Rizom ein Trieb mit nicht panaschierten Blättern wächst. Ich habe die Pflanze seit 2009 und sie hat im vorigen Jaht geblüht. Soll ich den Trieb entfernen und wie ist die "Rückentwicklung" überhaupt möglich?

JA, Du solltest den Trieb entfernen, da er deutlich kräftiger wachsen dürfte als die panschierten Triebe und damit die restliche Pflanze "überwächst"
Schließlich hat er mindestens doppelt soviel Clorophyll zur Verfügung wie diese.

Im Detail kann ich es auch nicht erklären, da kein Botaniker.
Die Panaschierung selbst ist aber auch nur eine Mutation, von daher sind Rückmutationen immer im Bereich des Möglichen.
Entscheidend ist wie die Panschierung in der Pflanze bzw. den Zellen angelegt ist.
Vereinfacht: Kommt also ein neuer Trieb aus einem Bereich der Pflanze wo die Panschierung nicht hinterlegt ist, wir dieser normal grünblättrig.

Hallo,

wir haben mit dem alten YuccaundCo-Forum ein wunderbares Archiv zur Verfügung das viel zu wenig genutzt wird.
Hier mal mein Senf zum Thema: gucks du hier

Hallo,

ich danke Euch für die schnelle Antwort. Da werde ich den Trieb bald entfernen und an anderer Stelle einpflanzen. Mal sehen, was daraus noch wird.

Horst, ich habe im alten Forum nachgelesen. Was ist denn nun aus Deiner Pflanze geworden?

Hallo Roland,

die steht im Topf und ist von einer normalen filamentosa kaum zu unterscheiden.

Hello,

I also have a plant which is now forming an all green rosette of leaves. I am very happy for this - Why? you may ask! Well, when this all green plant is big enough to bloom, and I pollinate the flowers, the seeds will be fertile, which they usually isn't on Yucca 'Golden Sword' :-)

Happy growing

Benny

Hello Benny ,
I had little success (5 plants still alive and growing vigorously) in crossing Yucca 'golden sword' with Yucca rigida (golden sword was the mother plant).
Yucca 'golden sword' is not totally sterile at all , but yes, you are right in saying that this cultivar is less fertile.
So , are you quite sure that the origin of this partial sterility is due to the variegation ?
I do seedling of Yucca rostrata x Yucca rostrata that were almost albinos too (90 % ratio of albinos !) , even if the parents were normal blue green plants...
That shoud be very interisting to see if the seeds will be more fertile using a green 'golden sword' (we'd better to call it 'green sword' now ) , only the future will tell..
best regards , fred

Hello Fred,

Great news, how many % of the seedlings of the Yucca 'Golden Sword' x rigida had chlorophyll? Did the seedpod have any green stripes?

The answer to your question if the partial variegation is the reason to seedlings without any chlorophyll, before your discovery I would say yes - always, but only if the variegation is a center variegation as with Yucca 'Golden Sword'. It is different with Yucca 'Bright Edge' this one produces seeds which is very good and all seedlings are green.

In Hosta the same problem arise. But according to the very known Hosta Breeder Hans Hansen, U.S.A, you might get a few green seedlings, but only if the fruit is variegated and not plain yellow!

Bechtold had a Yucca 'Golden Sword' which had a variegated seed pod, but I don't know if there did come a few green healthy seedlings from it. I did not have any luck with the seeds from that pod.

I have also seen a few albino seedlings from "selfpollinated" seeds. I always hand-sorting, the seeds so I only sow seeds which "feel" good, If I just sown the lot, I might see this phenomenon more often.

Best growth to all.

Benny

Hello Benny ,
the ratio of green seedlings is about 3% in the case of the hybrid Yucca 'golden sword' x Yucca rigida , and the seed pods were a little bit variegated and others pure green.
I have also do Yucca 'golden sword' x Yucca recurvifolia , and the ratio is more high , I had obtained 4 green seedlings for a total of 15 sowed seeds (all germinated , so that mean 4 green and 11 albinos).
Today 2 plants of this last hybrid are still alive (others dies at an early stage because of a lack of water during my holiddays)
best regards , fred

Hello Fred,

That's alright with so fine germination-rates. Yes, seedlings can may not be dry for very long, or they will wither and die. This is the reason, why I do not send young seedlings by post, unless the plant has started to grow a small rhizome.

Do you have any recent photos of the Yucca 'Golden Sword' x rigida seedlings? I would love to see how it look.

Have a nice day

Benny

Hello Benny ,
yes I have pictures taken today in the 'bildergalerie' , they grow vigorously, the plants are 13 months old exactly . Notice the red colour at the base of the leafs.
best regards , fred.

Hello Fred,

The hybrids looks really great and they have a good size for such young plants. The flaccida genes with the red "stress color" at the base of the leaves is very dominant in this hybrid, hope it keeps the color when it grows bigger.

Thanks for sharing.

Benny

Hello and thank's you Benny ,
The leafs are also very rought on both side and the margin are serrated.
The red color appeared when the temperature was hight during the day (25°c) and cold at night (8/10°c) .
Best regards , fred
