橡胶树人工授粉的座果率很低。1969—1980年马来西亚橡胶研究院进行的杂交试验表明,在第一个主要开花季节授粉的平均座果率是3％,第二个开花季节授粉的平均座果率是8％。 Heusser(1919)和Maas(1919)曾研究过橡胶树花的生物学并试图人工授粉,他们发现大多数人工授粉的花至三周时掉落,这可能是授粉失败的原因。以后,Morris(1929)、Ross(1960)和Wycherley(1971)
Rubber tree artificial fruit pollination rate is very low. Hybridization tests conducted by the Malaysian Institute of Rubber Research from 1969-1980 showed that the average fruit set rate for pollination in the first major flowering season was 3% and the average fruit set rate for pollination in the second flowering season was 8%. Heusser (1919) and Maas (1919) studied the biology of Acacia flowers and attempted artificial pollination. They found that most artificial pollination dropped to three weeks, which could be responsible for the failure of pollination. Later, Morris (1929), Ross (1960) and Wycherley (1971)
