Plant Growth and Development
Solution:
The term parthenocarpy refers to development of
fruit without fertilisation. Such fruits, e.g. banana, pineapple
are seedless but otherwise normal in appearance. The auxins
($IAA, IBA$ and $2, 4-D$) are applied in low concentration in a
lanoline paste to the stigma of flower to induce parthenocarpy.
