除了开放授粉外，还对四个泰国榴莲品种“Mon Thong”、“Chanee”、“Kradum Thong”和“Phaung Manee”进行了人工自花授粉和异花授粉，以调查授粉对坐果的效率。在所有品种中，开放授粉处理导致的坐果率最低，收获时的坐果率为 0% 至 1.4%。这可能是由于缺乏授粉造成的。自花授粉处理也导致坐果率较低，尤其是“Mon Thong”（7.7%）、“Chanee”（3.6%）和“Phaung Manee”（0%），这表明榴莲存在自交不亲和性。当‘Kradum Thong’用作花粉亲本时，泰国领先品种‘Mon Thong’的坐果率显着较高（27.2%）。 “Kradum Thong”花粉在“Chanee”（16.3%）中也实现了高坐果率，尽管其值与测试的其他花粉亲本的值没有显着差异。强烈建议在商业榴莲种植中使用“Kradum Thong”作为授粉剂进行人工异花授粉。体内花粉管生长观察表明，自花授粉不抑制柱头花粉萌发和花粉管花柱伸长。因此，榴莲似乎具有迟发性自交不亲和性。
Artificial self-pollination and cross-pollination were performed in addition to open pollination in four Thai durian cultivars, ‘Mon Thong’, ‘Chanee’, ‘Kradum Thong’ and ‘Phaung Manee’, for investigating the efficiency of pollination to fruit set. In all cultivars, open pollination treatment resulted in the lowest fruit set, ranging from 0 to 1.4% at harvest. This may be due to lack of pollination. Self-pollination treatment also resulted in lower fruit set, especially in ‘Mon Thong’ (7.7%), ‘Chanee’ (3.6%) and ‘Phaung Manee’ (0%), indicating a self-incompatibility in durian. When ‘Kradum Thong’ was used as pollen parent, fruit set percentage was significantly high in ‘Mon Thong’ (27.2%), which is a leading cultivar in Thailand. High fruit set was also achieved in ‘Chanee’ (16.3%) by ‘Kradum Thong’ pollen, although its value was not significantly separated from values of other pollen parents tested. Artificial cross-pollination using ‘Kradum Thong’ as a pollinizer was strongly recommended for commercial durian cultivation. The observation of pollen-tube growth in vivo revealed that pollen germination on stigma and pollen-tube elongation in style were not inhibited by self-pollination. Thus, durian seems to have a late-acting self-incompatibility.
