我經常聞到九重葛有香味，好聞芳香味，但懂九重葛者知道，目前只有國外一樹狀品種(arborea--18基本種之1)號稱具有香味，國內沒有具香味品種，但我確實在一盆嫁接幾種Mrs.Eva品系的混接盆上同時開的花，每一品種均聞到不弱的芳香味，不是一天，是天天持續不短日數。---->引起我探究興趣!!


先看看這兩篇


1.花如何吸引授粉者:

2.

**


1.洋文這篇清楚的介紹九重葛有蜜腺/花蜜及國外各地授粉昆蟲


2.第一篇清楚介紹顏色/香味/花蜜如何吸引昆蟲


3.九重葛的花苞不是花，中心管狀的小花才是花


4.昆蟲授粉要先有香味/顏色吸引它，再有甜點(蜜)引它頭/口器深入(針對長管花)


5.Mrs.Eva品系具結籽能力，亦可見到昆蟲拜訪，理應有蜜腺花蜜


6.香味來源可能是花瓣或蜜腺，要聞到香味，理應等到小花展開後


您說我聞到香味合不合理???


1.但我無法解釋為何只有我聞到，二羊兄家的聞不到，或我家同品種為何不是每盆均可聞到!!


2.能否聞到與小花打開與扭轉閉口(短短幾天)有無關係? (我那盆有將所有花管剪斷)


3.可結籽有蜜腺推論，不結耔(不可育)品種就一定沒花蜜? 應不一定，因不可育品種的花上亦常見昆蟲光顧，是否可育另有它因!


4.如其他品種也有花蜜那為何沒聞到香味? (戶外/花管閉鎖/蜜腺不發達/有味不濃...?)


5.葉子就沒香味? 因我也曾在它品種葉子聞到!


待解!

Google : bougainvillea fragrance or scent


0.http://wiki.answers.com/Q/Does_the_bougainvillea_have_scent


"Most varieties of bougainvillea have little or no scent. Those that do smell very slightly like hot honeysuckle"


1.http://www.streetdirectory.com/travel_guide/194559/gardening/bougainvillea_for_your_backyard.html


"Bougainvillea has a nice fragrance which is similar to that of the Honeysuckle plant. "


2.http://www.bgi-usa.com/fragrant-bougainvillea-arborea/


"I find myself smelling bougainvillea again, but this time enjoying a scent similar to honeysuckles.  I got my wish after all!  Unbeknownst to many, Bougainvillea ‘Arborea’ is the only known variety that is fragrant. I think it’s a wonderful variety for its lack of thorns, bushy habit, mass flowering, and the best part – fragrant blooms!"


3.http://www.warrenparknursery.com.au/library/bougainvillea/none/araroma


"Fragrant and thornless. This is the ultimate screening bouganvillea. Extremely dense growth makes it a great screening plant. Has a sweet scent like a jasmine."


4.http://www.gardenguides.com/113594-care-bougainvillea-flower-plant.html


"Bougainvilleas are beloved for their flowers and brightly-colored, large bracts, some of which are fragrant"

 


"Bougainvillea is a beautiful climbing plant that is native to Brazil, but was exported in the 1700's. Only one species of Bougainvillea has a scent, which is similar to Honeysuckle."

*Potential Pollinators: Small insects. The opening in the flower is small only enough to fit small insects, or insects with mouths, that have long tongues such as bees.
The Bracts around the flower are coloured, which helps to attract pollinators to the plant.

‍Nectar information:

We found a small amount of nectar present in the flowers, with acts a a reward for visiting pollinators.

‍Pollen information

The pollen is fluorescent, when placed under UV light, therefore attracts many pollinators. The pollen is round in shape.
