Abstract
The response of the photosynthetic apparatus to low temperature periods differed among 3 hybrids of maize (Zea mays L.) grown in a phytotron. Light-saturated photosynthetic rates, leaf chlorophyll content and mesophyll cell photosynthetic unit density declined with increasing duration of low temperature. No single metabolic or physiological parameter appeared to control the response of the 3 hybrids to low temperature stress. Among all temperature treatments, net photosynthetic rate on a leaf area basis was more closely correlated with leaf chlorophyll content than with any other measured parameter. Final shoot dry weight was most highly correlated with stomatal conductance to CO2.This publication has 11 references indexed in Scilit:
