为了提高水仙的观赏价值,本文用四种植物生长调节剂(烯效唑、多效唑、矮壮素、比久)对水仙植株进行处理,结果表明:在四种生长调节剂中,虽然矮壮素和比久对叶片和花葶生长都有较明显的抑制作用,但多效唑和烯效唑的矮化效果却要好很多。四种生长调节剂对根长生长没有明显的促进或抑制作用。同时,水仙的花期受四种调节剂的不同程度的影响,与对照相比,花期延迟在2-19天之间。通过相关分析可以看出,水仙花花期延迟的天数和处理浓度有很显著的相关性。由此可见,适宜浓度的植物生长调节剂可以使水仙植株矮化,花葶缩短,叶片变小,株型紧凑,直立平稳,明显提高园艺观赏价值。表4参11。
In order to improve the ornamental value of narcissus, the four plant growth regulators (uniconazole, paclobutrazol, chlormequat, for a long time) to deal with the narcissus plant, the results show that: in the four growth regulators, although the CCC And longer than the leaves and scallops have a more significant growth inhibition, but paclobutrazol and uniconazole dwarf effect is much better. Four growth regulators did not significantly promote or inhibit root growth. In the meantime, the flowering period of narcissus was affected to varying degrees by four regulators, and the flowering delay was between 2 and 19 days compared with the control. Through the correlation analysis, it can be seen that there is a significant correlation between the number of days delayed flowering and the treatment concentration. Thus, the appropriate concentration of plant growth regulators dwarf plants daffodils, scape shortening, smaller leaves, compact plant type, upright and steady, significantly improve the ornamental value of horticulture.
