摘  要:
经亚麻荠叶片表面形态及其表面细胞结构观察发现,亚麻荠叶正面上刚毛密度平均为76.13根/cm2,而背面仅为1.63根/cm2;表皮细胞层较厚,结构紧密,其上有一层较厚的角质层。通过亚麻荠叶片饲喂小菜蛾幼虫明确,小菜蛾幼虫在亚麻荞叶片的正面和背面的取食叶面积差异极显著。表明亚麻荠叶片表面的毛状物对小菜蛾幼虫有一定的拒食作用。

摘  要:
False flax, a kind of oil-bearing crop, is highly resistant to phytophagous insects. Its leave structure shows some resistance characters to insects, such as the trichomes on the leave surface. Compared with cabbage, false flax had thicker leave cuticle, compacter and thicker epidermal stratum. In addition, the content of cellulose in false flax was also higher than that in cabbage.
