The paraffined section of samples observed under microscope shows that the female organs develop well and successd in passing the stage of fertilization, The reason of the empty fruit is that the primary endosperm nuclei cease to divide further as would be otherwise expected as soon as the formation of free nuclei. Consequenfly, the zygotes are deficiercy in organic nu(?)ri(?)nfs necessary for developrment, thus resulting in their failure of developping into embryo. Hence, the empty fruit occurs.To avpid this phenomenon, the supply of nutrients proved needed cluring the developmeut period of blastala.
