Pongamia pinnata, is an important biodiesel plant in India. The seed is an economic part of the plant used for extraction of biodiesel. The reproductive biology of P. pinnata is important for determining barriers in setting pods. The study has been carried out at Central Agroforestry Research Institute, Jhansi, India, during 2017–2019. The observations were made on the floral biology and pollinator activity in P. pinnata for 2 years. Anthesis was noticed between 0800 and 1000 h with peak anthesis between 0800 and 0830 h. Flower longevity was only 1 day. Pollen dehiscence occurred 1–2 h before anthesis. Pollen remained viable throughout the day with maximum germination (96.15%) coinciding anthesis time. Whereas, maximum pollen tube length (0.54 ± 0.10) was observed during 1000 h. Stigma remained receptive for 8 h after anthesis, the maximum receptivity was noticed 2 h after anthesis (82% of pollen germination) and it was coinciding the time where maximum pollen tube length recorded. The style was longer than stamens, indicating that the flower appeared to be adapted for cross-pollination. There were 13 flower visitors recorded, of which Megachile species were more abundant compared to Apis, Xylocopa species and, other flower visitors. The pollinator exclusion experiment was conducted to assess the role of flower visitors on pollination and fruit set. No pod set was noticed in the absence of insect pollinators. Whereas, in an open-pollinated condition, pod set ranged between 15 to 18%.

Pongamia pinnata，是印度重要的生物柴油厂。种子是用于提取生物柴油的植物的经济部分。P.pinnata的生殖生物学对于确定荚果的壁垒很重要。该研究于2017-2019年期间在印度占西的中央农林业研究所进行。对P.pinnata的花生物学和传粉媒介活性进行了观察。2年。花期在0800至1000 h之间，而花期在0800至0830 h之间。花的寿命只有1天。花粉开裂发生在花前1-2小时。花粉全天保持活力，最大发芽率（96.15％）与花药时间一致。而在1000小时内观察到最大花粉管长度（0.54±0.10）。花后8小时柱头仍能接受，花后2小时观察到最大接受度（花粉发芽的82％），这与记录最大花粉管长度的时间一致。花柱长于雄蕊，表明花似乎适合异花授粉。记录了13位花客，其中比阿皮斯（Apis）的大叶菊物种更丰富，木薯种和其他花卉访客。进行了授粉媒介排斥实验，以评估花访客对授粉和坐果的作用。在没有昆虫传粉者的情况下，没有发现豆荚。而在开放授粉条件下，豆荚集在15％至18％之间。
