从2014年起对山楂的不同长度和粗度结果母枝的成花能力,自花、单性、自然授粉的结实能力,以及顶、腋花芽的比例和成花能力等开花结果习性进行观察试验研究,从而掌握山楂的若干开花结果习性。结果表明:山楂结果母枝的质量对其成花能力影响很大,长、壮结果母枝成花能力非常明显地强于短弱母枝;山楂具有一定的自花结实和单性结实能力,人工辅助授粉可明显提高坐果率;山楂形成腋花芽的能力很强,腋花芽是主要的结果部位。
From 2014 onwards, we observed the flowering habits such as flower bud ability, self-flowering, unisexuality, the ability of natural pollination, the ratio of top and axillary flower buds and flower forming ability of hawthorn with different length and thickness. Research, in order to master the hawthorn of a number of flowering habits. The results showed that: the quality of the hawthorn parent had a great influence on its ability to flower, long and strong fruiting branches fruiting ability is significantly stronger than the weak and weak mother; hawthorn has some self-flowering and parthenocarpy, Artificial assisted pollination can significantly improve the rate of fruit set; Hawthorn axillary bud formation is very strong, axillary bud is the main result of the site.
