Leaf Abscission Induced by the Iodide Ion.
In the course of biological screening for herbicidal activity in synthetic compounds, various organic iodide complexes had marked defoliating properties when applied to leguminous test plants. Simple iodides such as the salts of alkali metals also caused defoliation. Although this effect has been reported in the patent literature (4, 8), our present investigation was undertaken principally to l...
متن کاملEthylene-induced Leaf Abscission Is Promoted by Gibberellic Acid.
Gibberellic acid (GA(3)) promoted leaf abscission from cotton (Gossypium hirsutum L.) plants exposed to ethylene. With mature plants, only the rate of abscission was increased, but when vegetative plants were exposed to ethylene for 4 days or less, the amount of abscission was increased markedly. Promotion of abscission occurred at near saturating ethylene levels (10 mul/liter), over a wide ran...
متن کاملImpact of NaCl on leaf abscission, ion content and photosynthetic indices of seven commercial Fig (Ficus carica.L) cultivars
The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...

متن کاملThe Rate of Oxidation of Iodide Ion by Hydrogen Peroxide
T HE practice of chemistry is concerned very largely with the carrying out of chemical reactions whereby new substances are produced from old. The substances entering into the reaction are'known as reagents, and the substances produced as products. One of the factors in chemical reactions which is subject to human control and manipulation is summarized in the Law of Mass Action. This law, in si...
