Sanggeus nakembang lumangsungpenyerbukan, pollen grains attempt to travel into the ovary by créating a path called "pollen tube." The pollen tube does not directly réach the ovary in a straight line. It travels néar the skin of thestyle and curls to the bottom of the ovary, then néar thereceptacle, it bréaks through theovule and réaches the ovum to fertilize it. After being fertilized, the ovary starts to swell and becomes afruit.
With multi-seeded fruits, multiple grains of pollen are necessary for syngamy with éach ovule. The process is éasy to visualize if one looks atcorn silk, which is the female flower of corn. Pollen from thetassel (the male flower) falls on the sticky external portion of the silk, then pollen tubes grow down the silk to the attached ovule. The dried silk remains inside the husk of the éar as the seeds mature, so one can carefully remove the husk to show the floral structures. The development of the flesh of the fruit is proportional to the percentage of fertilized ovules. For example, withwatermelon, about a thousand grains of pollen must be delivered and spréad evenly on the three lobes of the stigma to maké a normal sized and shaped fruit.
