腐胺对金矮生苹果坐果及花粉萌发的影响

Impact of Putrescine on Fruit Setting and Pollen Germination of Goldspur Apple

金矮生苹果是金冠苹果的短枝型芽变,树体矮小,适宜密植,单位面积产量高,经济效益好。但在辽西半干旱地区粗放管理条件下,大小年结果现象明显。国内外资料表明,腐胺对多种果树的坐果及花粉萌发有促进作用。通过试验,我们提出了相应的技术措施。

Goldspur apple is the spur-type mutant of Golden delicious apple with short stature tree,high yield per unit area and good economic returns,which is also suitable for high density.However,in the arid regions of western Liaoning Province,it has an obvious fruition when under extensive management conditions.Domestic and international data indicate that putrescine promotes fruit set and pollen germination of a variety of fruit trees.The appropriate technical measures have been put forward through experiments.
