Factors affecting pollination quality of apple tree

Pollination quality of apple trees directly affect the apple tree fruit, so we must ensure the quality of the apple tree pollination, in order to ensure the good harvest, fruit pollen manufacturers sorted out a few factors affecting the quality of apple tree pollination for the majority of farmers, hoping to arouse the attention of everyone!
The morphology and living power of pollen (pollen grains scattered on the pistil) directly affect pollination and fertilization. Pollen grains with small shape, irregular shape, and no pollen holes or too many holes were all aborted pollen, while short shoot varieties (such as Liquan short Fu, Jin -18 short branch red Fuji) had more complex pollen morphology, which would facilitate the spread of bees.
(2) the species and content of mineral elements (calcium, boron and other trace elements) in the pollen. The variety and content of mineral elements in pollen affect the germination of pollen and the elongation of pollen tube, thus affecting the fertilization effect.
(3) light. Light has a certain effect on flowering. Generally, sunny days with better light intensity are good for flowering. But too strong illumination can accelerate the drying of the mucus secreted by stigma, which is not conducive to the attachment and germination of pollen.
(4) the effect of temperature. Low temperature is an important factor affecting pollination and fertilization. It not only affects flowering, but also affects pollen germination and pollen tube growth and pollinating insect activities. The suitable temperature for the flowering of apple is 17 C -18 C, and the suitable temperature of pollen germination and pollen tube growth is 10 C, -25 C.
(5) the way of pollination. The different method of pollination not only affects the fruit setting rate after pollination, but also affects the tidy degree of fruit and the size of the fruit. The most influential is the pollination of the bee (wall bee).
