e4“Gelrite causes more HH since medium solidified with Gelrite liquefies, probably because of chelating compounds excreted by plant tissues”

Other claims from this paper (6)
- Mechanism Flooding of the apoplast is the major causative factor of hyperhydricity.
- Mechanism Flooding reduces gas exchange by cells, leading to anaerobiosis and accumulation of gases such as ethylene.
- Intervention effect Adding salicylic acid to close the stomata increased hyperhydricity.
- Mechanism Root pressure translocates water from the roots to the apoplast.
- Mechanism Water in the apoplast cannot easily be removed in vitro by transpiration because of very high headspace humidity.
- Mechanism Gelrite-solidified medium liquefies, probably because of chelating compounds excreted by plant tissues.
