Photosynthate translocation to the root in loquat trees decreases as fruit develops. Thus, during the most active period of fruit development, that is, from 50 % of its final size to the beginning of fruit color change, ...
Fruit load restricts the flowering promotion effect of paclobutrazol in alternate bearing Citrus spp

Martínez Fuentes, Amparo; Mesejo Conejos, Carlos; Muñoz Fambuena, Natalia; Reig Valor, Carmina; Gonzalez Más, Mª Carmen; Iglesias, D. J.; Primo Millo, Eduardo; Agustí Fonfría, Manuel (Elsevier, 2013-02-28)

The floral bud inductive period, PBZ promotes flowering in Citrus; however, our results indicate that this effect is fruit-load dependant. In 'Salustiana' and 'Navelina' sweet oranges, 'Hernandina' Clementine mandarin, and ...

Reig Valor, Carmina; Farina, Vitorio; Mesejo Conejos, Carlos; Martínez Fuentes, Amparo; Barone, Francesca; Agustí Fonfría, Manuel (Springer Verlag (Germany), 2014-06)

The effects of fruit on bud sprouting and vegetative growth were compared on fruiting and defruited loquat trees from fruit set onward. Carbohydrate and nitrogen content in leaves and bark tissues and hormone concentrations ...
Fruit-dependent epigenetic regulation of flowering in Citrus

Agustí Fonfría, Manuel; Mesejo Conejos, Carlos; Muñoz-Fambuena, Natalia; Vera Sirera, Francisco José; de Lucas, Miguel; Martinez Fuentes, Amparo; Reig Valor, Carmina; Iglesias, Domingo J.; Primo-Millo, Eduardo; BLAZQUEZ RODRIGUEZ, MIGUEL ANGEL (Blackwell Publishing, 2020-01)

[EN] In many perennial plants, seasonal flowering is primarily controlled by environmental conditions, but in certain polycarpic plants, environmental signals are locally gated by the presence of developing fruits initiated ...
