Why do some osmanthus trees bear fruit and some do not?

As the saying goes, "Sweet-scented osmanthus bears strange fruit". In ancient times, the fruit of osmanthus tree was a symbol of good luck. Song Wenzhi, a poet in the Tang Dynasty, wrote a poem "laurel leaves in the middle of the month, fragrant clouds outside", which refers to the phenomenon that osmanthus trees bear fruit. Recently, the netizen "Walking Color Shadow" found a osmanthus tree hanging fruit in the Yuan Mingming community of Xiuzhou District where he lived. He thought it was strange, so he filmed it and posted it online. It is also rare for netizens to see photos. What is the cause of the result? Then why do osmanthus trees bear fruit? The netizen "flowers are still fragrant" gave the answer. She told the Post that the fruit of osmanthus tree is called Guizi, because it has the same sound as "Guizi" and has been regarded as a symbol of good luck since ancient times. In the south, it is not unusual for osmanthus trees to blossom and bear fruit. As long as the trees are mature and the surrounding water, fertilizer, temperature, soil and air are suitable, osmanthus trees, like other trees, will also blossom and bear fruit. "Generally, most of the osmanthus trees we see are cut down, and these osmanthus trees will not bear fruit; But osmanthus trees bred with seeds will bear fruit. " "The fragrance of flowers remains the same" means. Is it correct to say that the flowers are still fragrant? Subsequently, the reporter found another statement about this phenomenon on the Internet: osmanthus trees generally bloom from September to 10 every year and mature in April of the following year. In fact, the flowering and fruiting of osmanthus trees are not unusual, but the performance of individual differences. Osmanthus fragrans is bisexual like most flowers. A flower has both stamens and pistils, so osmanthus trees are male and female. When the male flowers on a tree are in the majority, the osmanthus tree will only blossom and will not bear fruit; Otherwise, the result will be. At present, because most osmanthus fragrans are male flowers, there are not many opportunities for people to see osmanthus trees bear fruit.
