Pressurized liquid. The stem is inserted into the water balloon, where the elasticity of the balloon maintains a slight pressure.Carmen wrote:Rik: the balloon technique sounds interesting! Just to be clear, the stem is squeezed between balloons inflated with water? or inserted in a pressurized liquid? thank you!
The culprit is usually that air has gotten into the cut-off plant part's vascular system. The leaves can pull water up only so long as there is a solid column of liquid in their vascular tubes. When you cut the plant, you expose the tubes to air, and the damage is done.leander wrote:I usually do have a small vial of water they sit in when I shoot them but that doesn't help with the quick wilters. Something physiologically happens inside the plant when the stem is cut. Is it a change in pressure? Does the plant release chemicals or other signal molecules that triggers wilting? Hummm.
Esteemed Chris S. This makes sense. And I really appreciate the comments relayed from the botany profesor you worked with. I would expect him/her to be the best qualified for a satisfactory causal explanation. Much obliged!Chris S. wrote:The culprit is usually that air has gotten into the cut-off plant part's vascular system. . .
Brilliant! I very much admire your inventiveness. By chance, do you have any photo's posted of your stage?Chris S. wrote: . . . Another thing I find that helps is to include a leaf, or portion of a leaf, above the structure to be photographed. Then shine a bright light on that leaf, so that it actively photosynthesizes. Photosynthesis requires water, so the leaf will start pulling it up from the vase. A photosynthesizing leaf also transpires water out of its stomata which likely adds to the sucking force. In my experience, this can materially help keep water in the structurea I want to photograph . . .
