Talking about the difference between fruit and pollen germination and growth of pollen

After the study found that different species each flower pollen count and pollen grains drug is different, and therefore the amount of pollen, there are big differences, that Apple, pollen grains per anther for 8428, while only pears 1197, there is unity between the different species of trees are significant differences, then there is between the amount of pollen and pollen germination and fruit trees grow what difference?
       Because different species of fruit trees, species and growth conditions, flowering sooner or later, the length of flowering, there are big differences, for earlier flowering trees, flowering is often because of the lower temperatures, rainy weather or insects between plants pollination activities, the situation of poor pollination and fertilization occurs, resulting in a large area of ​​fruit drop or a serious impact on the quality of pollen, for this phenomenon is that people tend to use artificial pollination method, which not only solved the poor pollination caused the production problems, but also to promote the fruit enlargement, increasing fruit size, correct channels and improve the quality of the fruit, but because of the people for many fruit trees and flowers as well as how much weight anther pollen germination rate level is not very clear, artificial pollination time, there are some blind nature of the dosage.
       These content exists between the growth and development of the problem is the variety of fruit trees, this series of high-tech issues are also under slowly resolved, and will also be producing more high-quality varieties.
