| 摘 要： | 对低温及低温下药剂处理对李花粉萌发的影响进行了研究，结果表明：低温能明显降低李花粉萌发率，尤其会减慢花粉萌发和花粉管伸长速率。400mg／L的硼酸能极显著提高花粉萌发率，低于此浓度促进作用不显著，高于此浓度则有抑制作用；钼酸钠在10～40mg／L浓度范围内均有显著的促进作用；萘乙酸在5～10mg／L低浓度下促进作用显著，20mg／L及其以上浓度却有显著抑制作用；赤霉素则以100mg／L和50mg／L的高浓度促进作用显著，而在5mg／L和10mg／L的低浓度效果不显著。除了5mg／L的萘乙酸能显著促进花粉管的伸长外，其它各处理对花粉管伸长的影响均不显著。

| Abstract: | Effect of temperatures, mineral nutrients and plant growth regulators (PGRs) used at low temperature on germination rate of pollen and growth of pollen tubes were studied with plum cul-tivars as experimental materials. Low temperature obviously decreased germination rate of pollen , and especially slowed growth of pollen tubes. 400 mg/L boric acid,10-40 mg/L sodium molybdate, 5-10 mg/L a-naphthalene acetic acid and 50 mg/L and 100 mg/L gibberellic acid significantly or very significantly promoted pollen germination,but 100 mg/L and 200 mg/L boric acid and 5 mg/L and 10 mg/L gibberellic acid had not significantly promoting effect on it and boric acid at higher concentration (> 400 mg/L) significantly decreased it. AI1 treatments had not significantly effect on growth of pollen tubes except for 5 mg/L crnaphthalene acetic acid which significantly promoted it. |
