摘　　要：采用离体花粉培养技术,研究了不同浓度Ca^(2+)对葱兰花粉萌发和花粉管生长的影响。结果表明:较低浓度的Ca^(2+)(1×10^(-3)～1×10^(-5)mol/L)对花粉的萌发有一定的促进作用,能较快的促进花粉管的伸长,其中以Ca^(2+)(10^(-3)mol/L)作用最明显;而高浓度的Ca^(2+)(10^(-1)～10^(-2) mol/L)则对其有一定的阻碍和抑制作用。The effects of Ca^2＋ on the pollen germination and tube growth of Zephyranthes candida were studied with different concentrations of Ca^2＋ through tissue culuture. The results showed that low concentrations of Ca^2＋（ 10^-3～10^-5mol/L） can promoted the pollen germination and tube growth. Ca^2＋ with a concentration of 10^-3mol/L signifi-canfly promoted the pollen germination and tube growth. The pollen germination and tube growth were inhibitedwhile the concentration of Ca^2＋ was higher than 10^-3mol/L .
