摘　　要：为抑制海南地区红掌季节性佛焰苞耳部变绿(俗称"绿耳")的发生,以盆栽品种‘大哥大’(‘Dakota’)为试验材料,研究不同Ca2+浓度处理对红掌佛焰苞季节性"绿耳"的生理效应。结果表明:随着Ca2+处理浓度增加,佛焰苞的"绿耳"发生率降低,且耳部色相a*值和彩度C*值均显著提高,佛焰苞中总花青素苷含量显著增加,叶绿素含量显著降低。增施Ca2+还有利于促进佛焰苞中可溶性糖和可溶性蛋白的积累。综合以上研究结果可知,从7月份开始增施浓度在8~10 mmol/L范围内的Ca2+,可使佛焰苞"绿耳"现象得到较好的改善。To inhibite the appearance of seasonal ＂Green ear＂ of anthurium spathes in Hainan, the physiological effects of different concentrations of Ca2＋ on the potted cultivar ＇Dakota＇ were investigated. The results showed that with the increase of Ca2＋ concentration, the incidence of ＂Green ear＂ decreased and the color parameters a＊ and C＊ of the ear part of the spathe as well as the total anthocyanin content （TAC） enhanced significantly. In contrary, the content of chlorophyll dropped dramatically. The higher concentration of Ca2＋ was benefit for the accumulation of soluble sugar and protein in the spathes. The results indicated that the treatment of 8-10 mmol/L Ca2＋ since July could improve the anthurium ＂Gree ear＂.
