Other claims from this paper (13)
- Intervention effect Growth reduction under 90 mM NaCl was smaller in rootstock-grafted cucumber than in nongrafted and self-grafted plants.
- Intervention effect Under 90 mM NaCl, net photosynthetic rate and stomatal conductance were significantly decreased in nongrafted and self-grafted cucumber.
- Intervention effect Grafting cucumber onto pumpkin rootstock alleviated the NaCl-induced reductions.
- Intervention effect Under 90 mM NaCl, intercellular CO2 concentration was significantly increased in nongrafted and self-grafted cucumber.
- Intervention effect Under 90 mM NaCl, intercellular CO2 concentration was decreased in rootstock-grafted cucumber.
- Intervention effect Under 90 mM NaCl, NPQ and the deepoxidation state of the xanthophyll cycle were significantly increased, particularly in rootstock-grafted cucumber.
- Mechanism Rootstock-grafted cucumber appears to have higher potential to dissipate excess excitation energy, reducing photodamage to PSII.
- Intervention effect Under 90 mM NaCl, the number of grana was reduced in cucumber chloroplasts.
- Intervention effect Under 90 mM NaCl, the thylakoids of cucumber chloroplasts were swollen.
- Intervention effect Under 90 mM NaCl, starch granules accumulated in cucumber chloroplasts.
- Intervention effect Chloroplast ultrastructure damage under NaCl was alleviated in rootstock-grafted cucumber.
- Intervention effect Use of C. moschata rootstock alleviated salt stress in cucumber plants.
- Mechanism Rootstock use may alleviate photoinhibition in cucumber, probably through fewer stomatal and nonstomatal limits on photosynthesis.
