Auxin and gibberellin effects on cell growth and starch during abscission in cotton.
An increase in starch content of cells in the abscission zone of the cotton explant appeared correlated with an increase in number of cells. A large increase in the number of cells in the abscission zone, concomitant with an increase in starch content, followed treatment with gibberellin as compared to auxin. In the final stages of abscission starch was hydrolyzed in the cells of the separation...
متن کاملEffect of Oxygen Tension on the Course of Ethylene- & Gibberellin-Induced Foliar Abscission.
' Received Sept. 27, 1962. ing 125 mm being miiade up with either argon or ethylene. The followiing gas mixtures were used: air, 10 % 02 + 90% A, 7.5% O., + 92.5 % A, 5% 02 + 95% A. In other experimlenits the partial pressure of ethylene in the jars was varied from 0 to 253 nim Hg, while the O. level was maintained at 5 % and total pressure adjusted to 760 mim with argon. For comparative purpos...
متن کاملHormonal control of isoperoxidases in lentil embryonic axis.
Detachment of the cotyledons from the lentil (Lens culinaris Med.) embryonic axis causes in the latter an increase in total peroxidase activity which is shown to be due to enhancement of specific cathodic isoperoxidases. Kinetin treatment of attached or detached axes promotes activity of essentially the same cathodic isoperoxidases. In addition kinetin enhances the activity of two anodic peroxi...
متن کاملStimulation of Lettuce Seed Germination by 6-(Substituted) Purines.
Presoaking several varieties of seed, especially lettuce, in various 6(substituted) aminoand thiopurine solutions has been found to increase their rate of germination (3, 5, 6). Recently it was also reported that these purine derivatives are synergistic with gibberellin in inducing these biological responses whereas gibberellin alone was only moderately active in stimulating germination of Earl...
متن کاملEffects of Kinetin , IAA , and Gibberellin on Ethylene Production , and Their Interactions in Growth of Seedlings " 2
A bstract. Kinetin in concentrations of 10-e to 10-4 M, stimuated ethylene production in 3 and 4-day old etiolated seedlings of Alaska pea (Pisucm sativum L. var. Ala-ka). Seedlings of other species responded similarly. The response to kinetin depended on the age of the seedlings. Kinetin alone did not influence ethylene production in 6-day old stem sections, but it greatly increased the enhanc...
