Kinetics of growth retardant and hormone interactions in affecting cucumber hypocotyl elongation.
The capacities of indole-3-acetic acid (IAA) and gibberellin A(3) (GA(3)) to counteract the inhibitory effects of (2-chloroethyl) trimethylammonium chloride (CCC), 2-isopropyl-4-dimethylamino-5-methylphenyl-1-piperidinecarboxylate methyl chloride (Amo-1618), and N,N-dimethylaminosuccinamic acid (B-995) on hypocotyl elongation in light-grown cucumber (Cucumis sativus L.) seedlings were investiga...
متن کاملHormonal interactions in the control of Arabidopsis hypocotyl elongation.
The Arabidopsis hypocotyl, together with hormone mutants and chemical inhibitors, was used to study the role of auxin in cell elongation and its possible interactions with ethylene and gibberellin. When wild-type Arabidopsis seedlings were grown on media containing a range of auxin concentrations, hypocotyl growth was inhibited. However, when axr1-12 and 35S-iaaL (which have reduced auxin respo...
متن کاملDose and Timing of Brushing to Control Excessive Hypocotyl Elongation in Cucumber Transplants
Brushing is an effective method to control hypocotyl elongation in cucumbers (Cucumis sativus L. ‘Turbo’) grown in plug trays for transplanting. The amount of daily brushing and the number of days to brush for best performance was determined. Treatment with 10 strokes per day for the 4 days of maximal hypocotyl elongation was sufficient to reduce final hypocotyl length by 25%. More brushing did...
متن کاملFurther Comparisons between Carbowax 6000 and Mannitol as Suppressants of Cucumber Hypocotyl Elongation.
Stirring largely eliminated the greater effectiveness of Carbowax 6000 compared to mannitol in reducing cucumber (Cucumis sativus L.) hypocotyl section elongation. Stirring increased elongation in water but reduced elongation in growth regulator solution. Shrinkage of cells without plasmolysis in hypertonic Carbowax solutions indicates that Carbowax 6000 did not penetrate cell walls. Sections p...
متن کاملHormone-solute interactions in the lettuce hypocotyl hook.
The hypocotyl hook of the lettuce (Lactuca sativa cv. Grand Rapids) seedling is stimulated to a high degree of curvature through a synergistic interaction of ethylene and gibberellic acid in the light. Presentation of various inorganic salts to the seedlings caused extensive alteration of the hormone-induced curvatures, with ammonium and sulfate being the most stimulatory of curvature, and pota...
