| 中文摘要: |
| 本试验采用HOBO温湿度记录仪测定菊花桃0℃~7.2℃低温累积值，当菊花桃需冷量达到760、780 h即2月下旬时，分别进行不同浓度的赤霉素药剂喷施，观察其物候期、生物学性状的变化。试验结果表明100 mg/l的赤霉素喷施效果显著，可促使萌芽期延迟、花期提前且延长、提高花开的整齐度和正常开花，改善菊花桃在福建存在花期短、花量少、花开不整齐或不能正常开花、花叶同开的问题，具有较大的推广价值。 |
| 英文摘要: |
| This test used the HOBO temperature and humidity recorder to record the low temperature cumulative value of 0℃~7.2℃ in ‘Juhuatao’ peach. Different concentration of gibberellin sprayed respectively when the chilling requirement reached 760, 780 h that it was in late February. Made an investigation with the change of the phenophase and biological character. The result showed that the sprout period of ‘Juhuatao’ peach would delay, the flower would bloom normal, the flower period would ahead and extend, and the uniformity of flowering would improve with 100 mg/l gibberellin sprayed. It improved the problem of ‘Juhuatao’ in Fujian that the flower with short, few, irregular, abnormality, and flowers and leafes unfolded at the same time. It had great popularization value. |
