  Re: [Aroid-l] Do green spathes assimilate?

Hello Marek,

By assimilation I am assuming you mean photosynthesis.  Using the example of Spathiphyllum, since the spathe is a modified leaf, it most certainly does produce photosynthate for the overall metabolism of the plant once the spathe becomes green, usually with age and/or after pollination.  Even the pollinated spadix that greens up after pollination with support photosynthesis, although maybe not as efficiently as the leaves.  Where there is chlorophyll there is photosynthesis.

Regards, Scott

Subject: [Aroid-l] Do green spathes assimilate?

Many aroids have green spathes and usually they are the tallest parts of the plants.
In deep shade in forests spathes are often green, olive-green, brown, it indicates the presence of chlorophyll.
Some other aroids' spathes turn green as the flowers become pollinated (like Spathiphyllum).
Do the green spathes play a role in assimilation?
