| 摘 要： | 榔榆盆景植物施用多效唑后,对其当年及第二年的生长均有显著的抑制效应,在浓度为50～200mg/L范围内,随处理浓度递增,使新梢生长量、冠幅、叶面积减小,叶片厚度、叶绿素含量增加越明显。处理株与对照相比,叶片内源激素IAA的含量明显减少,ABA含量增加;边缘分生组织和板状分生组织的活动受抑;海绵组织、栅栏组织及表皮层增厚。应用多效唑可以改善榔榆的株型,并提高榔榆盆景的观赏价值。

| Abstract: | The young trees of potted Ulmus parvifolia were treated with paclobutrazol (PP333). The effects of PP333 on the plant growth were obvious, and the after-effects were also very distinct. Within the concentration of PP333 100~200 ppm, there showed the inhibition of the growth of shoots, crowns and leaf area, but the leaf thickness and the content of chlorophyll were increased. PP333 also caused the decrease of the content of IAA and the increase of ABA in the leaves. During the leaf growth and development, the plate meristem and marginal meristem were inhibited by PP333, but it could increase the thickness of palisade tissue, spongy tissue and epidermis. All these effects greatly improved the enjoying value of the potted Ulmus parvifolia. |
