[EN] The asexual flower set in the loquat is a rare phenomenon. However, in some cases,
depending mainly on the low temperatures during filling, aspermos fruits appear. This
phenomenon exists in many fruit species and ...

[ES] El cv. Rojo Brillante de caqui (Diospyros kaki Thunb.) sólo produce flores pistiladas y el
ovario presenta una alta capacidad partenocárpica. Sin embargo, y tras el cuajado, los
frutos sufren una caída fisiológica ...

[EN] Parthenocarpy allows fruit set independently of fertilization. In parthenocarpic-prone tomato genotypes, fruit set can be achieved under pollen-limiting environmental conditions and in sterile mutants. Parthenocarpy ...
[EN] Citrus is a wide genus in which most of the cultivated species and cultivars are natural parthenocarpic mutants or hybrids (i.e. orange, mandarin, tangerine, grapefruit). The autonomous increase in GA(1) ovary ...
Background: We have identified a kind of parthenocarpy in zucchini squash which is associated with an incomplete andromonoecy, i.e. a partial conversion of female into bisexual flowers. Given that andromonoecy in this and ...

[ES] La partenocarpia se produce cuando un ovario se desarrolla sin la fecundación de
sus óvulos y, por tanto, sin sus semillas. Este fenómeno es común en muchas especies y

GA 2-oxidases regulate gibberellin levels in ovaries and axillary buds of tomato plants and their silencing is responsible for parthenocarpic fruit growth and branching inhibition.Gibberellins (GAs) are phytohormones that ...
Parthenocarpy is becoming an essential trait for off-season greenhouse production of Zucchini squash. Given that winter conditions promote a reduction in the number of male flowers and in the activity of pollinators, the ...
