Abstract
Pot cultivation experiments using different light intensities were used to study the effects of Alternaria azukiae(hara)comb.nov. on Trifolium repens L., specifically on its cell membrane permeability, pigmentation, MDA, protein, and proline contents, and the activities of its SOD, POD, and CAT enzymes was shown that the infection of A. azukiae increased permeability of cell membrane, electric conductivity,over-oxidation of cell membranes and MDA content, and decreased pigment, protein, and proline content in T. repens leaf tissue. With the decrease of the light intensity, the changes of the above-mentioned indices were more significant. The electric conductivity and the MDA content were negatively related to light intensity, the correlation coefficient were -0.9957 and -0.9942; whereas pigment,protein and proline content were positively related to it. After inoculation with A.azukiae, the pigment content of the leaves of T. repens decreased notably, and under lower light (shaded to 75% of natural sunlight), the effect of A. azukiae on the pigment content of T. repens leaves was greater than natural sunlight (100%). The content of Chla、Chlb、 Chl(a+b) and Chlt in the controls was significantly higher than that of the inoculation. Due to the stimulation of A.azukiae, the activate oxygen metabolism system was destroyed, the balance of the protective enzyme system was broken, the activity of SOD and CAT decreased notably, comparative to an obvious increase in POD activity. At the same time ,the activities of SOD,POD and CAT were positively related to light intensity, with correlation coefficientsof 0.9889,0.9863 and 0.9938.
