AB Date palm (Phoenix dactylifera L.) is an economically important dioecious plant relying on viable pollen for ideal fertilisation. This investigation analyses the influence of pollen viability, germination, and storage on enhanced pollination efficiency. Genetic diversity, environmental factors, and storage techniques influence pollen viability. Storage conditions significantly affect pollen viability; pollen stored at -30°C maintains higher viability than at 4°C or 28°C. The viability and nuclear integrity of stored pollen have been further proved through the acetocarmine test. Drone-assisted pollination has shown potential as an effective method, enabling large-scale and precise pollen application, though further research is needed to confirm its efficiency in date palm cultivation. Biotechnological methods, like genetic engineering and transcriptomic analyses, have enhanced pollen viability, stress resistance, and overall quality. Additionally, the advancement in pollen storage techniques has prolonged viability, boosting fertilisation potential. The breeding strategies focusing on genetic diversity and marker-assisted selection have optimised pollination efficiency and improved crop resilience. The metaxenic effects of diverse pollen sources were also examined, revealing significant impacts on fruit size and quality, with notable variations depending on the pollen source. The analysis emphasises the importance of modern pollination techniques and their integration with conventional pollen management to improve the fruit yield and quality of date palm.
