摘要
以盆栽金钱树为试材,研究植物生长延缓剂多效唑和烯效唑不同浓度水平灌根对其生长及观赏品质的影响。结果表明:与对照相比,各处理均能一定程度增加叶宽、叶厚及小叶鲜质量,但对小叶长、新芽数目及叶绿素含量则无显著影响。综合评价,处理2(200 mg/LPP333灌根)的效果最好,既对金钱树小叶形状的观赏品质呈现有利的调节作用,又不影响其新芽数目及叶绿素含量。
The effects of two kinds of plant growth retardant in different concentrations on the growth and orna- mental characters of Zamioculcas zamiifolia were studied with seedlings grown in 20 cm large pots. The results indi- cated that the width, thickness and fresh weight of the leaflet was increased to a certain extent after the plants were treated by each of the eight treatments compared to the control. However, the length of the leaflet, number of the newly emerged buds and the chlorophyll content were not significantly influenced by the treatments with plant growth retardants. Comprehensively speaking, the best effect was obtained by treatment No. 2 （root drenched with 200 mg/L for three times）, which could improve the ornamental characters of the Zamioculcas zamiifolia leaflet shape, but did not impact on the newly emerged bud number and the chlorophyll content of the seedlings.
