Parthenocarpy is undesirable in nut crops, such as pistachio, for which the seed is the edible part. Horticulturists have selected and propagated parthenocarpic cultivars of many plants, including banana , fig , cactus pear ( Opuntia ), breadfruit and eggplant .
Stenospermocarpy is the biological mechanism that produces parthenocarpy (seedlessness) in some fruits, notably many table grapes. In stenospermocarpic fruits, normal pollination and fertilization are still required to ensure that the fruit 'sets', i.e. continues to develop on the plant; however subsequent abortion of the embryo that began ...
In male sterile plants, the parthenocarpy expresses itself only sporadically on the plant with deformed fruits. It has been reported that plant hormones provided by the ovary seed (such as auxins and gibberellins) promote fruit set and growth to produce seedless fruits. Initially, without seeds in the fruit, vegetative propagation was essential.
An edible seed [n 1] is a seed that is suitable for human or animal consumption. Of the six major plant parts, [ n 2 ] seeds are the dominant source of human calories and protein . [ 1 ] A wide variety of plant species provide edible seeds; most are angiosperms , while a few are gymnosperms .
The domesticated species have larger fruits and larger yet fewer seeds. [8] Parthenocarpy is known to occur in certain cultivars of C. pepo. [9] [10] The leaves have three to five lobes and are 20–35 centimetres (8–14 in) wide. All the subspecies, varieties, and cultivars are conspecific and interfertile.
In contrast to parthenocarpy, which involves seedless fruit formation without fertilization, apomictic fruits have viable seeds containing a proper embryo, with asexual origin. In flowering plants, the term "apomixis" is used in a restricted sense to mean agamospermy, i.e. clonal reproduction through seeds.

For fruit with unfertilized seeds, exogenous auxin results in parthenocarpy ("virgin-fruit" growth). Fruits form abnormal morphologies when auxin transport is disturbed. [34] In Arabidopsis fruits, auxin controls the release of seeds from the fruit (pod). The valve margins are a specialised tissue in pods that regulates when pod will open ...
