摘要

本試驗測試二種電照方式組合三種燈泡對抑制菊花開花之效果。電照於夜間10時至凌晨2時以連續電照或10分鐘明期，20分鐘暗期，共8個循環之間歇電照組合三種不同光質之燈泡等六種電照處理，調查熄燈後之到花日數以判斷電照成功與否，以作為建議農民採用時之參考。量測三種燈泡之光質，鎢絲燈泡為一向上之曲線，自可見光漸緩緩上升至遠紅光，包含550 nm至1,100 nm之光束。23W黃光燈泡及白光燈泡均有545及610 nm兩個波長，其中以黃光於610 nm橙紅光具有較高光束流量，而其抑制開花之效果較白光省電燈泡佳。在四個參試品種中，以黃秀芳品種之到花日數最長，而電照抑制之效果最好。龍鳳紫品種之到花日數最短，而其電照臨界照度高，品種間之反應差異大。23W黃光省電燈泡之效果與100 W鎢絲燈泡之效果接近，而23 W白光省電燈泡之效果較差。間歇電照處理僅黃秀芳品種之鎢絲燈泡組約於33 lux以上照度時能有效抑制開花，其餘各品種、各種燈泡之間歇電照均未能有效抑制菊花開花。

Combinations of two lighting methods and three lighting bulbs were tested for their inhibition effectiveness of chrysanthemum flowering. Continuous lighting between 10pm and 2am, and cyclic lighting, which contained 8 cycles each with 10 min light and 20 min dark, combined with three lighting bulbs with different light quality were tested. Days to flowering after lights were turned off were observed to indicate the outcome of flowering inhibition. Light qualities of three light bulbs were measured. Spectral distribution of the 100W incandescent bulb was a slowly increasing curve from 550nm to 1100nm. Two peaks at 545 and 610nm were observed from the 23W yellow and white light bulbs. Since the yellow light had more quantum flux at 610nm, orange red light, its effectiveness of flowering inhibition was better than the white light. Four varieties were tested. The days to flowering of 'Huang-Shiou-Fan' after light-off was the longest of the four varieties and the inhibition was most effective. The days to flowering of 'Long-Fong-Zi' was the shortest and its critical light intensity was the highest. The responses among varieties were diverse. The inhibition effectiveness of the 23W yellow light bulb was similar with the 100W incandescent bulb, but better than 23W white light bulb. Cyclic lighting could be used only for 'Huang-Shiou-Fan', using the 100 W incandescent bulb above 33 lux. The flowering dates became earlier than the control when cyclic lighting was used for the rest of the varieties and bulbs.
