From classical Greek – Parthenos + Karpos – virgin fruit.

 

We all know that fertilization triggers the formation of an embryo – which in plants releases hormones for the production of the associated fruit.  But not all plants got that memo. Fruit is made without the eggs being fertilized.  BTW it also occurs in some animals – called parthenogenesis.

The common banana variety we eat is parthenogenic.  See it next to a species banana with tons of seeds!                        Thank you Aliquotthesciencespot !

Some plants evolved a natural form we call genuine parthenocarpia – it is found in pineapples, grapes, bananas, pears, figs and citrus.  These typically have none or only rudimentary seeds.  Completely seedless grapes are a coincidental product –  a whim of nature. Plant Specialists can help you grow seedless grapes in your home garden or rooftop ! Ask our Design Team for assistance in planning and set up.

Common seedless pineapple. Thank you Gardening Know How !

In plants, sometimes external stimuli (temperature and humidity) will release the hormone and spontaneous parthenocarpy begins.  It apples it can also be caused by the mechanical stimulation of the ovary or if the ovary is destroyed from frost.

Rare seedless apples caused by frost. Thank you Helpful Gardener !

Apart from some seedless fruit, there are some plants that produce stunted, very soft seeds, which are therefore not felt at all when eating. This is not the same, and of course has a totally different name – stenospermocarpia. LORD!

Rare stunted small seed in avocado.  Thank you Just Avocados !

Virginity can also be artificially induced by treating the flowers with auxins (natural plant hormones). This is how growers make seedless eggplant, cucumbers, watermelon and tomatoes. The list grows daily

Common to find now – Virgin seedless watermelon !       Thank you to Compare the Difference !

                                    BTW – the white “seeds” are actually empty seedless carpels.

           For help growing more and larger tomatoes ask our Garden care Team at Plant Specialist’s to treat the flowers with a natural plant auxin.
