The article presents a study which investigates the mode of action of Naphthaleneacetic acid (NAA) in promoting fruit abscission. It is said that NAA is a synthetic auxin analogue, used as an effective thinner to improve fruit size and quality in apple trees. However, its effects are difficult to predict and it sometimes results in excess fruit drop.

    The auxin-binding protein 1 (ABP1) has already been proved to be an extracellular receptor of auxin in single cell systems. Protoplasts of maize coleoptiles respond to auxin with an increase in volume. The 2-naphthaleneacetic acid (2-NAA), an inactive auxin analog, acts as an anti-auxin in...

    Callus culture of Canthium parviflorum Lamk. was established from leaf explants. Different growth regulators greatly influenced the growth of callus cultures. The callus from leaf explants is induced by inoculating the young leaf bits on MS medium supplemented with various auxins (2, 4-...

    Studies about anatomical and ontogeny of leaf abscission in pome fruit trees are scarce. The leaf fall occurs after the abscission zone is promoted, being a natural process in pome fruit, and it lasted from the fall until the first frost in southern Brazil. It is not known yet how long the...

    It was investigated whether premature fruit abscission in Prunus avium L. was triggered by a reduction in polar auxin transport (PAT). The capacity of pedicels to transport tritiated IAA ([3H]-IAA) via the PAT pathway was measured at intervals throughout flower and fruit development. The extent...

    The high level of physiological fruitlet abscission in litchi (Litchi chinensis Sonn.) causes severe yield loss. Cell separation occurs at the fruit abscission zone (FAZ) and can be triggered by ethylene. However, a deep knowledge of the molecular events occurring in the FAZ is still unknown....
