-Stimulated Exocytosis in Maize Coleoptile Cells
in the cytoplasm ([Ca 2 1 ] cyt ) were interpreted as representing changes in [Ca 2 1 ] cyt –sensitive exocytosis and endocytosis. A continuous increase in [Ca 2 1 ] cyt resulted in a sigmoidal increase in C m values with a half-maximal concentration at z 1 m M. The steep increase in C m values was followed by a variable slow phase in changing C m values. When [Ca 2 1 ] cyt increased at a rate ...
متن کاملGrowth of Maize Seedlings as Affected by Glucokinin and Insulin
1. Solutions of glucokinin and insulin, particularly those from which the easily dialyzable substances had been removed, increased the growth of roots and tops of young maize seedlings, as shown by comparisons with untreated seedlings grown in distilled water. 2. Strong solutions of crude glucokinin or of crude insulin repressed growth. 3. Seedlings from which the tips of the primary roots had ...
متن کاملGranular Size Effect of Clinoptilolite on Maize Seedlings Growth
Clinoptilolite has been successfully used in growing media for containerized horticultural and floricultural production. However, limited data exist on the effects and interaction between particle size and organic nutrient enrichment of the clinoptilolite. One granular (1-3 mm) and micronized (<30 μm) clinoptilolite was added to quartz sand, an inert growing substrate, at two doses (0.1% and 3%...
متن کاملOptimizing Seed Germination and Growth of Seedlings in Persian Walnut
The efficiency of conventional stratification methods for seed germination of walnut (Juglans regia L.), which uses long moist-chilling periods, is low. This experiment was conducted during winter to spring 2014 to optimize the seed germination of walnut ‘Chandler’ via changing growing media and removing seed mechanical dormancy. Fourteen treatments were tested. None of the seeds germi...
متن کاملFusicoccin Counteracts the Toxic Effect of Cadmium on the Growth of Maize Coleoptile Segments
The effects of cadmium (Cd; 0.1-1000 μM) and fusicoccin (FC) on growth, Cd(2+) content, and membrane potential (E(m)) in maize coleoptile segments were studied. In addition, the E(m) changes and accumulation of Cd and calcium (Ca) in coleoptile segments treated with Cd(2+) combined with 1 μM FC or 30 mM tetraethylammonium (TEA) chloride (K(+)-channel blocker) were also determined. In this study...
