摘要
以艳光、曙光和华光的一年生枝条作为试材,探讨不同低温处理时间和赤霉素浓度对提早促进油桃发芽的影响。结果表明:曙光、艳光和华光油桃在集中低温处理400h和赤霉素浓度为100mg/L处理下发芽率极显著高于其他处理,发芽率都达到了90%以上。曙光和艳光油桃在集中低温处理400h和赤霉素浓度200mg/L与集中低温处理400h和赤霉素浓度50mg/L的处理下发芽率达到了80%以上;华光油桃在集中低温处理500h与赤霉素浓度为100mg/L的处理下发芽率也较高,达到了87.8%。
Taking this year＇s branchs of the yanguang, shuguang and huaguang nectarina as material, Exploring different low-temperature treatment time with GA concentration on promoting early germination of nectarine. The results showed that： the germination rate of the shuguang, huaguang and yanguang nectarine＇s branches at the continuous 400-hour-low-temperature treatment and the GA concentration 100mg/L was significantly higher than that of other treatments, the germination rate has reached 90 percent, the germination rate of the shuguang and yanguang nectarine＇s branches at the continuous 400-hour-low-temperature treatment and the GA concentration 200mg/l or at the continuous 400-hour-low-temperature treatment and the GA concentration 50mg/l has reached 80 percent above; the germination rate of the huaguang nectarine＇s branches at the continuous 500-hour-low-temperature treatment and the GA concentration 100mg/1 was very high and the germination rate has reached 87.8 percent.
