| 英文摘要 | The parameters estimated from traditional a/c (i) curve analysis are dependent upon some underlying assumptions that substomatal co2 concentration (c (i)) equals the chloroplast co2 concentration (c (c)) and the c (i) value at which the a/c (i) curve switches between rubisco- and electron transport-limited portions of the curve (c (i)-t) is set to a constant. however, the assumptions reduced the accuracy of parameter estimation significantly without taking the influence of c (i)-t value and mesophyll conductance (g (m)) on parameters into account. based on the analysis of larix gmelinii's a/c (i) curves, it showed the c (i)-t value varied significantly, ranging from 24 pa to 72 pa and averaging 38 pa. t-test demonstrated there were significant differences in parameters respectively estimated from a/c (i) and a/c (c) curve analysis (p < 0.01). compared with the maximum ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) carboxylation rate (v-cmax), the maximum electron transport rate (j(max)) and j(max)/v-cmax estimated from a/c (c) curve analysis which considers the effects of g (m) limit and simultaneously fits parameters with the whole a/c (c) curve, mean v-cmax estimated from a/c (i) curve analysis (v-cmax-c (i)) was underestimated by 37.49%; mean jmax estimated from a/c (i) curve analysis (j(max)-c (i)) was overestimated by 17.8% and (j(max)-c (i))/(v-cmax-c (i)) was overestimated by 24.2%. however, there was a significant linear relationship between v-cmax estimated from a/c (i) curve analysis and v-cmax estimated from a/c (c) curve analysis, so was it j(max) (p < 0.05). |
