e2“The net photosynthetic rate, stomatal conductance, maximal and effective quantum yield of PSII photochemistry, photochemical quenching coefficient, and effective quantum-use efficiency of PSII in the light-adapted state of the nongrafted and self-grafted plants were significantly decreased under 90 mM NaCl”
e3“However, these reductions were alleviated when the cucumber plants were grafted onto the pumpkin (Cucurbita moschata Duch.) rootstock”

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 Under 90 mM NaCl, PSII photochemical efficiency and quenching traits were significantly decreased in nongrafted and self-grafted cucumber.
- 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.
