Senescence Factor & Abscission of Coleus Leaves.
In 1955 Osborne reported that petiole sections cut from senescent leaves of any one of many species could speed the abscission of excised and debladed bean petioles (5). The sections from senescent leaves speeded abscission if directly attached or if one attached an agar block on which they had stood for 24 hours. She "proposed that leaf abscissions may be controlled not only by endogenous auxi...
متن کاملDiuretic activity of the leaves of Coleus aromaticus Benth
The aqueous and ethanolic extract of leaves of Coleus aromaticus was evaluated for diuretic activity. Both extracts were evaluated by determination of urine volume and electrolyte concentration in albino rats. Results revealed that both the aqueous and ethanolic extract at dose 500mgl kg showed significant diuretic activity by increasing the total volume of urine and concentration electrolyte. ...
متن کاملPeroxidase Activity in the Abscission Zone of Bean Leaves during Abscission.
Peroxidase activity and localization in the abscission zone of bean leaves were studied histochemically and by gel electrophoresis. Deblading of bean leaves resulted in an increase in peroxidase activity in the abscission zone 2 to 4 days after deblading with highest activity just prior to separation. In debladed plants, the cell division in six to eight layers of cells preceded separation. An ...
متن کاملPectin esterase in relation to leaf abscission in coleus and phaseolus.
Pectin esterase (PE) activities in abscission zones, other portions of leaves, and adjacent stem tissues were compared in attached leaves and abscissing petioles (previously debladed) of Coleus blumei Benth. and Phaseolus vulgaris L., cv. Canadian Wonder. Earlier findings of Osborne in bean were confirmed and changes in PE activity in coleus were shown to resemble those in bean in some respects...
متن کاملEthylene-induced differential gene expression during abscission of citrus leaves
The main objective of this work was to identify and classify genes involved in the process of leaf abscission in Clementina de Nules (Citrus clementina Hort. Ex Tan.). A 7 K unigene citrus cDNA microarray containing 12 K spots was used to characterize the transcriptome of the ethylene-induced abscission process in laminar abscission zone-enriched tissues and the petiole of debladed leaf explant...
