Post-pollination biochemical changes in the floral organs of Rhynchostylis retusa (L.) Bl. and Aerides multiflora Roxb. (Orchidaceae)

If left unpollinated, the flowers of Aerides multiflora (Roxb.) and Rhynchostylis retusa (L.) Bl. can remain fresh for 17 and 24 d, respectively. However, they begin to wilt at 2 to 3 days after pollination (DAP) and 3 to 4 DAP, respectively, and become senescent at 5 DAP and 7 DAP, respectively. Wh...

Description
Summary:If left unpollinated, the flowers of Aerides multiflora (Roxb.) and Rhynchostylis retusa (L.) Bl. can remain fresh for 17 and 24 d, respectively. However, they begin to wilt at 2 to 3 days after pollination (DAP) and 3 to 4 DAP, respectively, and become senescent at 5 DAP and 7 DAP, respectively. When measured at two developmental phases -- Stage 1, start of wilting and Stage 2, progression to senescence -- all the floral organs from pollinated flowers had higher contents of total soluble sugars, reducing sugars, and free amino acids than those from unpollinated flowers.
