Objective:
To study the change of photosynthesis and chlorophyll fluorescence characteristics of Pinellia ternata around sprout tumble.
Method:
Tubers of P. ternata were cultured firstly at (25 +/- 1) degrees C for certain days, and then they were coerced under 37 degrees C stress in the same artificial climate boxes. The chlorophyll contents, photosynthesis and chlorophyll fluorescence during different stages of high temperature stress were measured.
Result And Conclusion:
After under high temperature stress, the chlorophyll contents, the ratio of chlorophyll a/b, photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (Tr), maximum fluorescence (Fm), quantum yield of PS II (phi (PS II)), intrinsic photochemical efficiency of PS II (Fv/Fm) and the chlorophyll photochemical quenching (qP) decreased, but the intercellular CO2 concentration (Ci), minimal fluorescence (F0), the chlorophyll nonphotochemical quenching (NPQ) increased.
