Fig. 3From: Enhancing xanthine dehydrogenase activity is an effective way to delay leaf senescence and increase rice yieldPlant height and chlorophyll content differences between wild-type and transgenic plants at different growth stages. a Appearance, b plant height, and c chlorophyll content of WT, Ri3 and OE9 at different growth stages. The seedling, full heading and maturation stages of rice were grown to 14d, 60d, and 90d after sowing, respectively. Values are means±SEM, n = 5(b) and 3(c). Significant differences (P < 0.05) are denoted by different lowercase lettersBack to article page
