Factors affecting pollination of apple trees

Fruit harvest, pollination is very important, there are many factors that affect the effect of pollination, the majority of farmers should be noticed in pollination!
1 (pollen pistil scattered on pollen morphology and viability) directly affect pollination and fertilization. Small shaped, irregular shape, no germination hole or aperture too much pollen were abortive pollen; and spur type (such as Liquan, Shanxi -18 rich short short branch red Fuji) pollen morphology is more complex, to carry the bee.
Types and contents of mineral elements (CA, B and other trace elements) in pollen. The types and contents of mineral elements in pollen affect the pollen germination and pollen tube elongation, thus affecting the effect of fertilization.
Light illumination. Light has a certain effect on flowering, the average light intensity is good, sunny day is conducive to flowering, but the light is too strong, it will make the stigma secretion of mucus accelerated drying, is not conducive to the attachment and germination of pollen.
The influence of temperature. Low temperature is an important factor affecting pollination and fertilization. It not only affects the flowering, but also influences the pollen germination and pollen tube growth and the activities of the pollination insects. The suitable temperature of apple blossom is 17 C -18 C, the optimum temperature of pollen germination and pollen tube growth is 10 -25.
The pollination way. Different methods not only affect pollination after pollination fruit rate, also affect fruit uniformity, fruit size etc.. And the most influential is the bee (wall bee) pollination.
