摘  要:
以黄花梨花粉为试材,研究蔗糖浓度、硼离子浓度、钙离子浓度、温度、湿度、pH、植物生长调节剂对黄花梨花粉萌发的影响,找到适合黄花梨花粉萌发的最佳环境条件。结果表明:蔗糖浓度为250 g/L是黄花梨花粉萌发的最适浓度;Ca2+浓度为100 mg/L时显著促进黄花梨花粉萌发,较高浓度对花粉萌发有抑制作用;硼离子浓度在0~250 mg/L时明显促进黄花梨花粉的萌发;pH 6.4最适于黄花梨花粉萌发;24℃最适于黄花梨花粉萌发;空气湿度越大越有利于黄花梨花粉的萌发:浓度5~10 mg/L的萘乙酸对黄花梨花粉萌发的促进作用明显;浓度5~200 mg/L的GA3处理明显促进黄花梨花粉的萌发;浓度5~10 mg/L的吲哚乙酸处理明显促进黄花梨花粉的萌发。

摘  要:
Taking pollens of Huanghua pear as experiment materials.the effect of temperature,sucrose density,B3+,Ca2+ concentration,humidity,pH,plant growth regulators on pollen germination of Huanghua pear were studied,find the best environment for germination of pear pollen conditions.The results showed that the pollen germination of Huanghua pear was remarkably promoted under the condition of 100 mg/L Ca2+.Relatively high restrained pollen germination.0~250 mg/L B3+,5~10 mg/L NAA,5~200 mg/L GA3 or 5~10 mg/L IAA obviously promoted the pollen germination,respectively.250 g/L sucrose density,pH 6.4 and 24℃ temperature were advantageous to the germination of pollens.The bigger the air humidity was conducive to the germination of pollens.
