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.

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