In the English summary of an article published in Vanilles & Orchidées (Musee interantional de la parfumerie, Edisud, 1993, page 88), one can read :
"Some orchid odourless at certain hours of the day, give their fragrance at sunset in tropical areas. This phenomenon attached to the photoperiodicity is common". Could you point out articles about that relation (fragance and photoperiodicity) in English, French, Spanish or Portuguese ? ********** Regards, VB _______________________________________________ the OrchidGuide Digest (OGD) [email protected] http://orchidguide.com/mailman/listinfo/orchids_orchidguide.com
