以四個包括白花、黃花及紫紅花等花色之多花菊品種為試驗材料,進行花頸長度抑制劑比較試驗,於 93年9月6日種植,並於93年10月13日噴施花頸長度抑制劑,包括亞拉生長素,巴克素,抑芽素,克美素,單克素和品全王等六種。結果顯示,克美素及單克素花頸長度抑制效果不明顯,克美素甚至會發生輕微藥害;抑芽素除葉片邊緣產生枯焦斑塊發生藥害外,且嚴重的抑制植株生長,完全停止抽長開花;品全王不僅不具抑制效果,反而有促進花頸長度增長的現象;效果最佳者為亞拉生長素與巴克素,和不噴施的對照相比,兩者花頸長度減少的百分比約在17%-26%之間,巴克素在1000倍濃度下效果類似慣用的亞拉生長素400倍濃度。

關鍵詞: 夏菜冬花、多花菊、花頸長度、生長抑制劑、巴克素

The Effect of SADH, Paclobutrazol, Maleic Hydrazide, Cycocel, Uniconazole and Pin-chuan-wan
on the Flower Peduncle Elongation Retarding of Chrysanthymum

Chen, Y. H., Y. C. Wang, Y. T. Chang and S. S. Wang

Summary

An experiment with four varieties and six different kinds of plant growth retardants, including SADH, paclobutrazol, maleic hydrazide, cycocel, uniconazole and pin-chuan-wan was conducted for the purpose of testing the effect on the inhibition of flower peduncle elongation of spraymum. Two kinds of retardants, including cycocel and uniconazole have no obvious retarding response. Maleic hydrazide have caused brown damage spot on leaf margin and retarded the growth of plants seriously, even no flowering. Pin-chuan-wan, a kind of local producted fertilizer, has no retarding response, but enhanced the flower peduncle elongation of spraymum. Paclobutrazol with the concentration of 100 ppm is effective, similar to the retardant SADH with the commonly used concentration of 2125 ppm in inhibiting the peduncle elongation of spraymum.

Keywords: Winter flower / summer vegetable cropping system, Spraymum, Flower peduncle elongation, Growth inhibitor, Paclobutrazol
