Unusual way of photosynthesis of my stemmed plants

[paranoid]

Hi,

I discover that my red-stem plants have a unusual way of photosynthesis. Instead of the usual, a string of bubbles from the leaves, the bubbles come periodically (30~50 secs or so) in big bubbles!! The funny thing is that I cannot see where the bubbles come from. Could be from the leaves, or it seem from below the sand. The release of bubbles are so fast I can't see from where.

So I wish to ask if this is normal?

Thanks!

The small O2 bubbles must have accumulated beneath a leaf and then floated out as a big bubble.

could be it from the roots?

It's probably from the roots. I can't remember the details anymore, but plants do release O2 at it's roots in a process that helps them convert nutrients in the soil to an absorbable form... helpful bacteria involved in it too.

Hi,

I have just bought the stemmed plants a week ago and so far the roots have not yet developed i think. Well, at least photosynthesis is occuring, unusual or not . I will keep a closer watch, will update where the bubbles originate from.

Thanks!

nah, that means the plant is farting

[ranmasatome]

must have been eating beans, onions or something..

[blueray]

Haha....I like that....eating onion...

If you are giving it enough nutrients, you should be seeing your stemmed plants growing, the roots could well be growing at the same rate. Fast growing stem plants can grow a lot in week.

This is a fairly common phenomenon with stem plants that have been cut... the O2 is released through the laceration. Do a simple experiment to see it. Pull out one of the plant, float it under the light. You should be able to see a steady stream of O2 from the cut end (that is if it has not healed - cut off the end if it has).

In your case the O2 is simply gathering in the gravel and then 'exploding' up when there is too much of the gas.

Hi,

I agree. Suspect the O2 will be consolidated in the voids of the substrate. Then will be released when the buoyancy is suffice. Thanks for clearing my doubts! For once I thought I have some unique farting plant! My red stemmed plant is Neasea sp. So far it has grown approx 1~2cm since 1.5 weeks ago, with new leaves shooting out, but in yellowish green colour, hoping turning red soon.

I also observed that roots have shot out from the stem of the plant which points downwards. Are they normal?

Thanks All,

Normal for roots to point downwards and grow from nodes of stemmed plants. Not normal if the stem is pointing downwards. (Your sentence construct was confusing, so I covered both cases. )

[paranoid]

Hee hee. Sorry for the confusion. Let me clarify. The roots point downwards, let the legs of a camera tripod. The stem of the plants are fortunately still straight up.

M glad it's normal.First time encounter of this type for me.

Thanks!
