摘  要

張元聰、王裕權、張錦興、王仕賢、林棟樑•2004•遮陰處理避免星辰花離春化之研究。台南區農業改良場研究彙報44:59~66。

本試驗以經過春化處理的星辰花,於平地定植時採用50%黑網或銀網遮光,降低環境中的日射量及溫度以避免逆春化現象。試驗結果發現遮光網處理雖然能降低白天的溫度,但日溫仍高達30℃以上,不能有效防止逆春化現象,但遮光處理尤其是黑網可減少日射量達露天的39%,能減少葉片曬傷,使得中、末期的切花品質較優良。品種則以百萬紫、百萬粉、水晶黃這三個品種整體表現最佳。

關鍵詞:星辰花、離春化作用、遮陰處理

Effects of Treat Shading Net to Avoid Devernalization of Statice

Chang, Y. T., Y. C. Wang., C. S. Chang., S. S. Wang and D. L. Lin

Summary

Six varieties of Statice was planted in the field with 50% black or silver shading net to assess the effects. The shading can reduce the temperature and direct radiation to prevent devernalization. The temperature under the net was reduced but still over 30℃ so can’t avoid devernalization. The black net can reduce the direct radiation to 39﹪, it can prevent sunburn on the leave. The statices have more leaf areas can produce higher cut flower quality in mid and late period of harvest. The varieties of “million purple”, “million pink” and “crystal yellow” grows well under all the shading treatments.

Key words: Statice, Devernalization, Shading
