据省农科院园艺所多年试验和对部分山楂生产园的调查,山楂异花授粉比自然授粉坐果率明显提高。异花授粉比自然授粉提高花朵坐果率31.3％,比自花授粉(单性结实)坐果率提高37.2％。另外,异花授粉的山楂果个明显增大,百果重增加27.5～34.2％,果梗粗壮,色泽好,果质佳。 According to the provincial Academy of Agricultural Horticulture for many years of testing and part of the Hawthorn Production Park survey, hawthorn cross-pollination than natural pollination significantly increased fruit set. Cross-pollination increased flower setting rate by 31.3% compared with natural pollination, which was 37.2% higher than that of self-pollination (parthenocarpy). In addition, cross-pollination of the hawthorn fruit significantly increased, an increase of 27.5 fruit to 34.2% fruit stem stout, good color, good quality.
