图3 苗期喷施外源物质对迟播油菜单株叶面积的影响 处理同表1。不同小写字母表示处理在0.05水平下差异显著。图a~c是苗期喷施外源物质对迟播油菜2022-2023年苗期(a)、蕾薹期(b)和花期(c)单株叶面积的影响; 图 d~f分别是苗期喷施外源物质对迟播油菜2023-2024年苗期(d)、蕾薹期(e)和花期(f)单株叶面积的影响。

Fig. 3 Effect of spraying exogenous substances at seedling stage on leaf area per plant of late-seeded rapeseed Treatments are the same as those given in Table 1. Different lowercase letters indicate significant differences at P < 0.05. Figures a-c show the effects of spraying exogenous substances at the seedling stage on leaf area per plant of dry matter at the seedling stage (a), bolting stage (b), and flowering stage (c) of late-seeded rapeseed in 2022-2023; Figures d-f show the effects of spraying exogenous substances during the seedling stage on leaf area per plant of dry matter in late-sown rapeseed at the seedling stage (d), bolting stage (e), and flowering stage (f) in 2023-2024.
