white flower
Bonjour,
A propos de certaines fleurs, mes flores précisent "rouge, (violet, bleu), parfois blanche" Effectivement, j'ai rencontré des Campanules , érythrones, jasiones, digitales... blanches Est-ce l'albinisme chez les fleurs ? les graines produites donneront elles des spécimens blancs ? Il me semble que ces anomalies apparaissent en fin de période de floraison. Avez-vous fait la même remarque ? I try to translate :-)) About some flowers, my books said "red (or purple, or blue), sometimes white". Indeed, I have met white Campanula patula, white Erythronium, white Jasione, white Digitalis "purpurea", etc... Are they albinos ? Does the seeds will give another white ? I think they appear at the end of the flowering period ? Did you think so ??? -- Alain (enlever le x) Mon village en Haute-Soule (loisirs, fleurs...): http://perso.club-internet.fr/jarailet Carnet de voyages : http://perso.club-internet.fr/jarailet/Randobal |

White flowers can occur when the gene(s) controlling the production of
floral pigment is defective. The mutation theoretically can occur in any flowering plant species. The white flowered character is usually recessive to the typical flower color. A plant with typically colored flowers does not usually change to white unless perhaps the plant become anemic in some way. Some species normally produce white flowers.

pollinators who are guided by smell rather than eyesight BRBR Perfectly true, but that is not what he meant. The night-blooming white species, like Angraecums, are always white. He was asking about species which normally have colored flowers, but sometimes turn up or are bred with white flowers. These will not smell any different than their normal colored siblings.

Suppose that indeed there are species that normally have colored flowers but that late in the season have white flowers. If this should be due to a hormonal inbalance or a disabling of enzymes then there might conceivably also be a different smell. If these white flowers are the result of a disabling of something these will be more likely to smell less rather than more strongly. Of course this is pure speculation, with not even the existence of "late-blooming white flowers" established. Pvr |
