Abscission: role of abscisic Acid.
The effect of abscisic acid on cotton (Gossypium hirsutum L. cv. Acala 4-42) and bean (Phaseolus vulgaris L. cv. Red Kidney) explants was 2-fold. It increased ethylene production from the explants, which was found to account for some of its ability to accelerate abscission. Absci is acid also increased the activity of cellulase. Increased synthesis of cellulase was not du to an increase in agin...

متن کاملRole of Cytokinin/Abscisic Acid Balance
Temperature stress during kernel development affects maize (Zea mays 1.) grain growth and yield stability. Maize kernels (hybrid A619 x W64A) were cultured in vitro at 3 d after pollination and either maintained at 25°C or transferred to 35'C for 4 or 8 d, then returned to 25'C until physiological maturity. Kernel fresh and dry matter accumulation was severely disrupted by the long-term heat st...
متن کاملFruit age and changes in abscisic Acid content, ethylene production, and abscission rate of cotton fruits.
The relationships of fruit age, abscisic acid (ABA) concentration, ethylene evolution, and abscission rates were studied in an effort to determine why cotton (Gossypium hirsutum L., cv. Deltapine 16) fruits rarely abscise more than 15 days after anthesis. Because abscission of cotton fruits is increased by conditions that limit photosynthesis, greenhouse-grown plants with fruits of various ages...
متن کاملAbscisic Acid: correlations with abscission and with development in the cotton fruit.
Abscisic acid was measured in developing cotton fruit (Gossypium hirsutum) by means of gas-liquid chromatography. High levels of abscisic acid occurred in correlation with abortion and abscission of young fruit, with low germination of immature seed, and with senescence and dehiscence of mature fruit. Declining or low levels of abscisic acid occurred in correlation with the period of most rapid...
