Growth and Light

Posted by gooblatz (My Page) on

Plants need light to grow, of course, but not every plant part needs direct light exposure. Stems and roots are examples of plant parts that don't need direct light. But what about flowers? Would the flowering part of a rose develop normally under an opaque hood provided that the rest of the plant were exposed to light? Generally, do flowers or fruits need light exposure for any reason?

RE: Growth and Light

While I haven't taken any time to research it or find any scientific cites, practical experience would indicate the answer to your question is no. Even very shade tolerant plants tend not to flower well if located in persistant or heavy shade.

RE: Growth and Light

Try it and see! Tie a black hood over some flower buds, and see how they develop.

I suspect one side consequence though is that the un-illuminated flowers won't be able to attract their normal pollinators, so won't get pollinated, and therefore won't develop any seeds.

Also post-flowering, the immature fruit of most plants are photosynthetic, needing light to help produce energy for the seed development.
