The auxin induced curvature of citrus petals.
The curvature of citrus petals was studied, using petals implanted in an agar-sucrose medium. Applications of indoleacetic acid and p-chlorophenoxyisobutyric acid and determinations of endogenous auxins indicate that the bending of citrus petals is an auxin-mediated process.
متن کاملA reappraisal of the Pyriculariaceae in Iran
The family Magnaporthaceae considered as a single-family placed in the order Magnaporthales. Currently, three distinct clades are phylogenetically distinguished in this order that one is referred as the Pyriculariaceae. The Pyriculariaceae is characterized as a novel family having new genera, new species, new combinations and neotypification (basionym). To taxonomically evaluate this family, an...
متن کاملDifferentiation between indoleacetic Acid and the citrus auxin by column chromatography.
A gradient elution column chromatography technique and a step-wise technique succeeded in differentiating between IAA and the citrus auxin. IAA was eluted ahead of the citrus auxin in both systems. The highest Avena curvature ever obtained from the citrus auxin occurred after the auxin had passed through the 2 purification techniques and a paper chromatography step. This is probably due to the ...
متن کاملRecent Findings on the Mechanism of Action of the Synthetic Auxins Used to Improve Fruit Size of Citrus
Among the existing techniques used to enhance final fruit size in citrus, the use of synthetic auxins gives good results. The effect and mode of action of these substances has been studied over the last eight years and reproducible results are obtained. These substances act through an indirect effect, reducing fruitlet growth rate and promoting abscission, thus reducing competition; and through...
متن کاملInhibition of Polar Indole-3-acetic Acid Transport by Cycloheximide.
Cycloheximide inhibits polar indoleacetic acid transport in midrib tissues of leaves of citrus (Citrus sinensis [L.] Osbeck) and poplar (Populus deltoides Bartr.) as measured by the donor-receiver agar cylinder technique. It appears that the mechanism of auxin transport inhibition by cycloheximide consists in arresting protein synthesis and not in the disruption of energy flow. The interpretati...
