Effects of potassium-deficiency on photosynthesis and energy dissipation in different rice cultivars

Shao Jian-lin Plant Nutrition and Fertilizing Science 2007

Other claims from this paper (18)

Intervention effect Potassium deficiency reduced net photosynthetic rate of flag leaves in both rice cultivars.
Intervention effect Potassium deficiency significantly suppressed growth of both rice cultivars.
Association In YFZ, Pn of flag leaves decreased with decreasing stomatal conductance and intercellular CO2 concentration.
Mechanism The reduction in Pn of YFZ could be accounted for by stomatal limitation.
Association In EJF, Pn decreased with Gs and Ci at lower photosynthetic photon flux densities.
Observation Light saturation point of EJF dropped to about 500 under potassium deficiency.
Observation Light saturation point of YFZ stayed stable at 1200 under potassium deficiency.
Intervention effect Under potassium deficiency, F'v/F'm, ΦPSII and qP were rapidly decreased with increasing PFD.
Intervention effect Under potassium deficiency, ETR was rapidly decreased with increasing PFD.
Intervention effect Under potassium deficiency, L(PFD), E and PP were dramatically increased.
Intervention effect Under potassium deficiency, NPQ was increased when PFD was below 1200.
Intervention effect Under potassium deficiency, NPQ fell below its control at higher PFD.
Observation Under potassium deficiency, Fm and Fv/Fm were significantly decreased.
Observation Under potassium deficiency, Fo increased.
Mechanism Potassium deficiency damaged the photosynthetic apparatus and caused photoinhibition in rice.
Observation The middle component qNm contributed largely to energy dissipation in rice under potassium deficiency.
Mechanism Part of excited energy could be transferred from PSII to PSI, reducing the pressure of dissipating energy.
Mechanism Potassium sensitivity of rice cultivars may be partly related to their protection capacity against photodamage.

Other claims from this paper (18)

Intervention effect N2 enhanced grain nitrate reductase and glutamine synthase activities relative to N1 under heat stress.
Intervention effect N2 enhanced grain nitrate reductase and glutamine synthase activities relative to N1 under drought stress.
Intervention effect N2 increased photosynthetic rate, PSII efficiency and instantaneous WUE relative to N1 under individual post-anthesis stresses.
Intervention effect N3 increased photosynthetic rate, PSII efficiency and instantaneous WUE relative to N1 under individual post-anthesis stresses.
Intervention effect Under combined stress, N1 usually significantly improved photosynthetic rate, PSII efficiency and instantaneous WUE.
Intervention effect Nitrogen application increased green leaf area, aboveground dry mass and height in association with increased photosynthesis.
Association Leaf nitrogen content per unit area explained variation in photosynthetic rate more accurately.
Intervention effect Post-anthesis heat stress decreased yield by reducing grain number and thousand kernel weight.
Intervention effect Post-anthesis drought decreased yield by reducing grain number and thousand kernel weight.
Intervention effect Combined post-anthesis stress decreased yield by reducing grain number and thousand kernel weight.
Intervention effect Combined stress reduced NUE more than individual heat or drought.
Intervention effect N2 significantly prevented decreases in yield and NUE relative to N1 under individual heat and drought.
Intervention effect N3 significantly prevented decreases in yield and NUE relative to N1 under individual heat and drought.
Intervention effect N1 was conducive to improving wheat productivity, WUE and NUE under combined stress.
Recommendation The authors recommend appropriately increasing nitrogen under individual post-anthesis heat or drought.
Intervention effect Heat after anthesis reduced grain number per spike and thousand kernel weight.
Intervention effect Drought after anthesis reduced grain number per spike and thousand kernel weight.
Intervention effect Combined stress after anthesis reduced grain number per spike and thousand kernel weight.
