摘要:
为提高水仙的观赏价值,探讨复合多效唑对水仙生长发育的影响,用不同的多效唑溶液对水仙鳞茎进行处理。结果表明:多效唑能抑制水仙的营养生长,使植株矮化粗壮,叶片碧绿、挺拔,不易倒伏,根白、短而壮;复合多效唑配方使平均叶长减少37.7%,花期延长2 d,花朵直径增加18.3%,延缓黄化叶片的出现,减慢叶肉薄壁细胞及其中叶绿体的解体,在后期维管束的结构相对完整,有效提高观赏价值。
Abstract:
To raise ornamental values of Narcissus tazetta var.chinensis,and to study the effects of compound paclobatrazol on the growth and development of narcissus,this plant was soaked in paclobatrazol of different concentrations. The results showed that paclobatrazol can inhibit the narcissus’s growth,dwarf the plants,strengthen the leaves while making them greener,prevent lodging,and make the roots stronger and shorter. An application of compound paclobatrazol has an effect of dwarfing 37.7% in the vegetative growth stage,prolonging the blooming for 2 days,increasing the flower diameter by 18.3%, postponing the appearing of yellow leaves, the decomposition rate of cells and the chloroplasts in parenchyma tissue of the leaves. In late ornamental days,vascular bundles are more completed, therefore increase the ornamental value of the plants.
