The role of jasmonic acid and gibberellins in plant ontogeny with special regard to fruit development
Jasmonic acid (JA) and its analogues attracted the interest of plant physiologists through its widespread occurrence within the plant kingdom, as effective promoters of senescence and as endogenous factors of plant development involved in different physiological processes.

El ácido jasmónico (JA) y sus análogos han despertado el interés de los fisiólogos vegetales debido a su amplia presencia en el reino vegetal, su eficacia como promotores de la senescencia, y su papel como factores endógenos en el desarrollo de las plantas, involucrados en diferentes procesos fisiológicos. Este artículo trata sobre el probable papel que dichos compuestos juegan en diferentes estadios de la ontogenia de la planta, especialmente en la germinación y el crecimiento de la plántula, en el crecimiento y la senescencia de los órganos vegetativos, así como en el desarrollo reproductivo, particularmente en los frutos. Las giberelinas (GAs) parecen estar involucradas en el proceso de regulación del cuajado de los frutos. Investigaciones en Carica papaya han demostrado que en los frutos jóvenes en desarrollo predominan las giberelinas biológicamente muy activas GA1 y GA3, mientras que en los frutos amarillos destinados a caer, predominan la GA55 y un conjugado neutro de GA1. La presencia de GAs poco activas en frutos senescentes podría correlacionarse con los procesos fisiológicos que conducen a la caída.

Jasmonic acid (JA) and its analogues attracted the interest of plant physiologists through its widespread occurrence within the plant kingdom, as effective promoters of senescence and as endogenous factors of plant development involved in different physiological processes. This paper deals with the possible role of these compounds at different stages of plant ontogeny. The attention is directed to the germination process and growth of seedlings, to the growth and senescence of vegetative organs, as well as to the reproductive stages of development, especially to fruit formation. The gibberellins (GAs) seem to be involved in the regulation of fruit set. Investigations in Carica papaya showed that the very active GAs A1 and A3 were dominant in young developing fruits, while GA55 and a neutral GA3 conjugate were the major components in yellow fruits destined for abscission. The occurrence of low active GAs in abscising fruits seems to be connected with the physiological processes leading to the abscission. |
